Recently a customer from the ThingWorx Academic Program sent in a sample program they were having problems with. They were trying to post data from a Raspberry PI using Python to their ThingWorx server. It turns out that their program did work just fine and was also a great example of posting data from a PI using REST. Here is how to set up this example. 1. Import the attached "Things_TempAndHumidityThing.xml" entity file. 2. from the PI run 'sudo pip install requests' 3. from the PI run 'sudo pip install logging' 4. from the PI run 'sudo pip install http_client' 5. Create a python file call test.py that contains this example code: #!/usr/bin/python import requests import json import logging import sys # These two lines enable debugging at httplib level (requests->urllib3->http.client) # You will see the REQUEST, including HEADERS and DATA, and RESPONSE with HEADERS but without DATA. # The only thing missing will be the response.body which is not logged. try:     import http.client as http_client except ImportError:     # Python 2     import httplib as http_client http_client.HTTPConnection.debuglevel = 1 # You must initialize logging, otherwise you'll not see debug output. logging.basicConfig() logging.getLogger().setLevel(logging.DEBUG) requests_log = logging.getLogger("requests.packages.urllib3") requests_log.setLevel(logging.DEBUG) requests_log.propagate = True #NYP Webserver URL in Thingworx NYP_Webhost = sys.argv[1] App_Key = sys.argv[2] ThingName = 'TempAndHumidityThing' headers = { 'Content-Type': 'application/json', 'appKey': App_Key } payload = { 'Prop_Temperature': 45, 'Prop_Humidity': 33 } response = requests.put(NYP_Webhost + '/Thingworx/Things/' + ThingName + '/Properties/*', headers=headers, json=payload, verify=False) 6. From the command line run, './test.py http://twhome:8080 e9274d87-58aa-4d60-b27f-e67962f3e5c4' except substitute your server and your app key. 7. A successful response should look like: INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): twhome send: 'PUT /Thingworx/Things/TempAndHumidityThing/Properties/* HTTP/1.1\r\nHost: twhome:8080\r\nappKey: e9274d87-58aa-4d60-b27f-e67962f3e5c4\r\nContent-Length: 45\r\nAccept-Encoding: gzip, deflate\r\nAccept: */*\r\nUser-Agent: python-requests/2.8.1\r\nConnection: keep-alive\r\nContent-Type: application/json\r\n\r\n{"Prop_Temperature": 45, "Prop_Humidity": 33}' reply: 'HTTP/1.1 200 OK\r\n' header: Server: Apache-Coyote/1.1 header: Set-Cookie: JSESSIONID=E7436D2E6AE81C84EC197D406E7E365A; Path=/Thingworx/; HttpOnly header: Expires: 0 header: Cache-Control: no-store, no-cache header: Cache-Control: post-check=0, pre-check=0 header: Pragma: no-cache header: Content-Type: text/html;charset=UTF-8 header: Transfer-Encoding: chunked header: Date: Mon, 09 Nov 2015 12:39:24 GMT DEBUG:requests.packages.urllib3.connectionpool:"PUT /Thingworx/Things/TempAndHumidityThing/Properties/* HTTP/1.1" 200 None My thanks to the customer who sent in the simple example.

Javascript, everyone knows it, at least a little bit. What if I told you that you could do serious data acquisition with just a little bit of Javascript and you may already have the tools to do it, right now on your "Off the Shelf" device. Node.js is a command line implementation of Javascript that can be run on common, credit card sized devices like the Raspberry PI or the Intel Edison. I suspect that if you already know about Node.js, you may have encountered its non-blocking asynchronous, "Call back", style of programming which can be a little different that most other languages which block or wait for commands to complete. While this can be a benefit for increasing performance, it can also be a barrier to entry for new users. This is the problem that Node Red really solves. Node Red is a web based Integrated Development Environment (IDE) that turns the "Call Back" style Javascript programming of Node.js into a series of interconnected Nodes, each Node of which represents a Javascript function which is connected by a callback to another node/function. A simple hello world program in Node Red would look something like this ( with annotations in red) : You can re-create this program using the Node Red IDE yourself. Here is a brief video (with no sound) which should familiarize you with how to create your own hello world flow. Video Link : 1333 How can you install Node Red on your own system to try it out? The good news is, if you have a Raspberry PI 2 with a NOOBS installed on it, Node.js and Node Red come pre-installed. If you do not already have it installed, or want to install it on your own system it is still pretty simple. Here are the steps: 1. Download and install Node.js (https://nodejs.org/en/download/) 2. Run the command:  sudo npm install -g --unsafe-perm node-red     Omit the sudo on windows (see http://nodered.org/docs/getting-started/installation.html  for more info) 3. You now have Node Red. To run it, just type: node-red  on your command line. 4. Using your web browser goto http://localhost:1880 and the Node Red IDE will appear in your browser. How about a real hardware integration example? Node Red comes with many built in Nodes and many more nodes you can add to connect to specific peripherals you may have on your device. Rather than provide a complete tutorial on Node Red, I will focus on discussing using this IDE to re-create a hardware integration that I created in the past using the Java SDK, The Raspberry PI, AM2302 Weather Station (see Weather Applications with Raspberry Pi | ThingWorx)​. This example contains detailed specifics on the attachment of the AM2302 Temperature/Humidity sensor to your Raspberry PI. I am going to assume you have the hardware already attached to your Raspberry PI as described in this tutorial ( https://learn.adafruit.com/dht-humidity-sensing-on-raspberry-pi-with-gdocs-logging/overview ). I am also assuming that you have installed the python based sample program described in this tutorial as well and you now have a python script called "AdafruitDHT.py" installed on your PI that produces the following output when it is run. pi@raspberrypi:~/projects/Adafruit_Python_DHT/examples $ sudo ./AdafruitDHT.py 2302 4 Temp=22.3*  Humidity=30.6% pi@raspberrypi:~/projects/Adafruit_Python_DHT/examples $ If you don't have any of this hardware installed, you can still proceed with this example and just create your own temperature and humidity values manually. We are going to connect the output of this python script directly to ThingWorx and sample its output value every 5 seconds. I will start assuming you do not have the Am2302 hardware and create simulated values. I will then replace them with the actual output of the python script as a final step. Polling versus Interrupt Driven Data Collection In the Java SDK version of this example, we are polling for changes in data. Every so many seconds our device will wake up and take a reading. How do we recreate the same effect in Node Red without having to push an inject button every 5 seconds. No. We need an input node that activates on its own every 5 seconds. The Inject Node will do this. Drag out an inject node and configure it as shown below. This is an input node so it will be starting a new flow. It will fire off every 5 seconds from the minute this sheet is deployed. Simulate Data Collection Lets generate a random humidity and temperature value before getting the actual data. For this node we will use a Function node. Drag one out and configure it as shown below. Here is the Javascript for this node so you can cut and paste it into this dialog. var tempF = Math.random() * 40 + 60; var tempC = (tempF-32)/1.8; var humidity = Math.random() * 80 + 20; msg.payload = {     "tempF":tempF,     "tempC":tempC,     "humidity":humidity     }; return msg;                                    Remember that the returned message is the message that the next node will receive. The payload property is the standard or default property of a message that most nodes use to pass data between each other. Here, our payload is an object with all of our simulated data in it. Lets Test it Out Connect the two nodes together and add a debug output node and deploy your sheet. The completed flow will look like this. As soon as you deploy you should see the following output in your debug tab and every five seconds another data sample will be generated. So how does this data get to ThingWorx? What we need to do is take this data and deliver it to ThingWorx in the form of a REST web service call. This is easier to do than it sounds. First off, lets create a Thing on your ThingWorx server that looks like this. Now give it these properties. Next, create an Application Key in the application keys section of the composer. Assign it to the "Administrator" user. Your keyId will of course be different. This key will be the credential you need to post your data. Installing the ThingRest Node Red Node To simplify the process of posting the data to ThingWorx, I have created my own custom node to post data. To install a custom node into your Node Red installation you have to find the directory Node Red is using to store your sheets in. By default this is a directory called ".node-red" in your home directory. On a Raspberry PI this directory would be /home/pi/.node-red. If you are running Node Red now, quit it by hitting control-c and cd into the .node-red directory. Below is the sequence of commands you would issue on your PI to install the ThingRest node. cd ~/.node-red npm install git+https://git@github.com/obiwan314/node-red-node-thingrest.git node-red                     The node package manager (npm) will install this new node automatically into your .node-red directory. Now re-run node-red and go back to your browser and refresh your Node Red IDE. You should now have a "REST Thing" node. Adding a REST Thing node to your flow Drag a REST Thing output node into your flow and configure it as shown below. Remember, your Application Key will be different than the one shown here. Also, your ThingWorx server URL may be different if your server is not on the same machine you are working on. Now connect it as shown below. When you deploy this sheet, you will be posting data to ThingWorx. Go back to your WeatherStation1 Thing in ThingWorx and use the Refresh button shown below to see your data changing. Wait, that is? Thats the whole data collection program? Yes. The flow above is the equivalent of the Java SDK code from the Java weather station example. Now for Some Real Data As promised, we will now replace the simulated data in the Generate Data node with real data obtained from the "~/projects/Adafruit_Python_DHT/examples/AdafruitDHT.py 2302 4" python command on your Raspberry PI using an Exec node. The exec node can be found at the very bottom of your node palette. It executes a command and returns the results as msg.payload to the next node in the flow. You may have noticed it has three outputs instead of one. In order these outputs are your Standard output, Standard Error and the integer return code of the process. Use the first output node to get the results of this command. Now Connect this in place of the Generate Data Node as shown below. At this point, we can't connect the collected data to the WeatherStation1 Thing because it is in the wrong format. It is console output and we need it in the form of a Javascript object. We are going to need a function to parse the console output into a Javascript object. Add the function node shown below. Here is the Javascript for cut and paste convenience. var temphumidArray=msg.payload.split(" "); var tempC = parseFloat(temphumidArray[0].replace("*","").split('=')[1]); var tempF = tempC *1.8 + 32; var humidity = parseFloat(temphumidArray[2].replace("%","").replace("\n","").split('=')[1]); msg.payload = {     "humidity":humidity,     "tempF":tempF,     "tempC":tempC   }; return msg;   Now msg.payload contains a javascript object identical to the one we were generating at random but now it is using real data. Connect up your nodes so they appear as shown below but when you deploy, don't expect it to work yet because there is still one problem you will have to get around. This python script expects to be run as the root user. How to run Node Red as Root You can start Node Red as root with the following command sudo node-red -u /home/pi/.node-red   Note that the -u argument is required to make sure you keep using the pi user's .node-red directory. If you loose your REST Thing node, you are not using the pi user's .node-red directory, but root's instead. If you see any error messages in your debug window, try re-attaching the the debug node to the Collect Data node and see what is being produced by the exec node. Don't forget to verify that your tempC,tempF and humidity properties are updating in ThingWorx. Lets Add a GPS Location You may have noticed that there is a stationLocation property on the WeatherStation1 Thing. Lets set that to a fixed location to complete this example of 40.0568764,-75.6720953,18. Below is the modified Javascript to update in the Parse Data node to add this location. var temphumidArray=msg.payload.split(" "); var tempC = parseFloat(temphumidArray[0].replace("*","").split('=')[1]); var tempF = tempC *1.8 + 32; var humidity = parseFloat(temphumidArray[2].replace("%","").replace("\n","").split('=')[1]); msg.payload = {     "humidity":humidity,     "tempF":tempF,     "tempC":tempC,     "stationLocation":"40.0568764,-75.6720953,18" }; return msg; What's Next? Node Red has many more nodes that you can add to your project through the use of the npm command. There is a GPIO node library you can install at https://github.com/monteslu/node-red-contrib-gpio which will give you input and output nodes for the GPIO pins on your PI as well, This library also supports accessing Arduino's attached to the PI over a USB cable which expand the possibilities for data collection and peripheral control.Hopefully this article has exposed you to the many other possibilities for connecting devices to your ThingWorx Server. The Rest Thing node is using the HTTP REST protocol to talk to ThingWorx. In the near future, with the Introduction of the ThingWorx Javascript SDK, a Node Red library can be created that uses ThingWorx AlwaysOn WebSockets protocol to communicate with your ThingWorx server which will offer even more capabilities and better performance.

Setting up the ThingWorx Server RemoteThing, ApplicationKey, and TunnelSubsystem Tunneling from the ThingWorx platform to an Edge Device can be easily done with a few preparation steps on the platform side: Create an ApplicationKey entity on the ThingWorx server so that the EMS or SDK you are using can authenticate with the platform Create a RemoteThingWithTunnels or RemoteThingWithTunnelsAndFileTransfer Thing for the remote device to bind to Either ThingTemplate will work, the only difference is if you want to use any native file transfer capabilities that are provided by ThingWorx In the newly created Thing, on the General Information page, click on the drop-down menu next to Enable Tunneling and select Override - Enabled ​Go to the Configuration​ section under ​Entity Information ​on the right and click on the Add My Tunnel ​button The Tunnel Name is used to identify what tunnel to use in the RemoteAccessWidget you will bind to the tunnel The Host will remain 127.0.0.1 because this is from the perspective of where the vnc server is to the remote device In my example they are on the same device The Port value should be the Port that the server is listening on This is typically 5900, but my vnc server is running on port 5901 for this example The App URI can be cleared out because we do not need to reference that file Here is a link to a further explanation on what the App URI is for: ThingWorx Tunneling App URI's The # of Connections and Protocol can remain their default values unless you have a reason to change them Navigate back to Home and look for the TunnelSubsystem under the Subsystems page Click on the TunnelSubsystem Click on the Configuration option on the left Modify the Public host name used for tunnels field and the Public port used for tunnels field to the host and port of your ThingWorx server Save and close the TunnelSubsystem Configuring the Edge Device For this example I'm going to keep it simple and set up an EMS (Edge MicroServer) instead of an SDK. This EMS will be on a totally separate device (an Ubuntu machine), while my ThingWorx server is on my local machine. Download the latest EMS onto a separate machine Configure the config.json file settings to match the server's host, port, and application key The ​tunnel​ block will be necessary to add as well, see below for an example of a working config.json file: Configure the config.lua file to match the name of the RemoteThingWithTunnels we created earlier; in this instance the name of my RemoteThing is ​EdgeThing​: Run the EMS and LSR (Lua Script Resource) The LSR EdgeThing​ will bind automatically to the RemoteThingWithTunnels we created earlier To verify there is successful connection between the platform and EMS go to the ​EdgeThing​'s Properties page and check to see if the ​isConnected ​property is currently set to ​true​ If it's not, please refer to this Help Center section for further troubleshooting. There is a list of error codes here. Installing a VNC Viewer and Server The next series of steps talks about configuring a VNC Server on the EMS machine and a VNC Client on the computer you are using to connect to the server. For this example I will be using packages tightvncserver, xfce4, xfce4-goodies, and vnc4server on my Ubuntu machine that hosts the EMS, and I will be using the tightvnc viewer available for download here. The following steps describe how to configure the Ubuntu machine so that it will be ready to accept vnc requests: I want to note that I am specifically using a 64-bit Ubuntu 14.04 LTS OS Run the following commands: sudo apt-get update sudo apt-get install xfce4 xfce4-goodies tightvncserver Run the vncserver and you will be prompted to setup a password I used password to keep it simple, but you will want to use something relatively secure We will want to kill this instance right away so we can proceed with further configuration vncserver -kill :1 ​Make a backup of the ​xstartup​ file in case things go awry mv ~/.vnc/xstartup ~/.vnc/xstartup.bak Create a new xstartup ​file to proceed with the setup nano ~/.vnc/xstartup Insert the following commands into the file, and they will be exercised every time the server starts or is restarted: #!/bin/bash xrdb $HOME/.Xresources startxfce4 & The first command in the file tells the VNC's GUI framework to reference the .Xresources file, which is where a user can change vnc settings The second command launches the XFCE -- the graphical software Ensure that the xstartup ​file has executable privileges: sudo chmod +x ~/.vnc/xstartup Start the server back up with vncserver For the machine that is being used to view the Mashup, install the tightvnc server from the link mentioned above. You should double-click the tightvnc-jviewer.jar file to run the viewer application now so it is up and ready for the ​Establishing a Tunnel ​section​. Creating the RemoteAccess Mashup This next portion of the tutorial covers creating the Mashup that will be asked by any user who wants to remote into the Edge device. Go to Composer Home and open the Mashup menu option on the left side of the screen Add a new Static or Dynamic Mashup Drag-and-drop a RemoteAccessWidget onto the Mashup Click on the RemoteAccessWidget and modify the RemoteThingName, TunnelName, and AcceptSelfSignedCertificates ​properties for the connection The RemoteThingName is the name of the Edge Thing the remote device is bound to The TunnelName is the name of the tunnel we added to the Edge Thing in the Configuration screen The AcceptSelfSignedCertificates is only used when using an SSL connection with self signed certs View the Mashup and the RemoteAccess Widget should have a green plus sign on it if the connection from the EMS to platform is up and connected Establishing a Tunnel The following section is the last part of the process where we actually establish a tunnel between the client, platform, and remote device. Open the Mashup with the RemoteAccess Widget if you closed it Click on the RemoteAccess Widget to being the wsadapter.jnlp download Once that has completed click on the wsadapter.jnlp file to run it Keep in mind that there is a default 90 second timeout defined in the TunnelSubsystem that will render the wsadapter.jnlp file useless and you will have to download a new one if the connection is not established within that timeframe If you receive the following error message you may need to reconfigure your TunnelSubsystem configuration options for your server because the thingworx-tunnel-launcher.jar was unable to be found at that address If you receive the following error message after you will need to modify your security settings in your Java options. This is done by opening ​Configure Java​, navigating to the ​Security ​tab, and then adding your ThingWorx server's IP and port to the site list via the ​Edit Site List...​ button You should have received a Security Warning message upon successfully finding the thingworx-tunnel-launcher.jar file that you will click the ​Run​ button on and check the I accept the risk and want to run this application​ A pop-up, like the following, will be seen and you know the tunnel is now open for tightvnc to connect through Do not click ​OK​, instead, please proceed to the next step. Clicking OK will close the tunnel if you have not connected to the EMS via the VNC Viewer yet. Open the tightvnc-jviewer.jar and type in the corresponding host and port that a vnc connection should be established to: localhost ​ and port ​16345​ are used because we have already established a connection to the EMS and it is listening for a vnc connection on port 16345 -- per the ThingWorx pop-up we just saw Click ​Connect​ and a new window should appear showing the GUI environment of your Ubuntu server like below

Below is where I will discuss the simple implementation of constructing a POST request in Java. I have embedded the entire source at the bottom of this post for easy copy and paste. To start you will want to define the URL you are trying to POST to: String url = "http://127.0.0.1:80/Thingworx/Things/Thing_Name/Services/​Service_to_Post_to​"; Breaking down this url String: ​http://​ - a non-SSL connection is being used in this example 127.0.0.1:80 -- the address and port that ThingWorx is hosted on /Thingworx -- this bit is necessary because we are talking to ThingWorx /Things -- Things is used as an example here because the service I am posting to is on a Thing Some alternatives to substitute in are ThingTemplates, ThingShapes, Resources, and Subsystems /​Thing_Name​ -- Substitute in the name of your Thing where the service is located /Services -- We are calling a service on the Thing, so this is how you drill down to it /​Service_to_Post_to​ -- Substitute in the name of the service you are trying to invoke Create a URL object: URL obj = new URL(url); Class URL, included in the java.net.URL import, represents a Uniform Resource Locator, a pointer to a "resource" on the Internet. Adding the port is optional, but if it is omitted port 80 will be used by default. Define a HttpURLConnection object to later open a single connection to the URL specified: HttpURLConnection con = (HttpURLConnection) obj.openConnection(); Class HttpURLConnection, included in the java.net.HttpURLConnection import, provides a single instance to connect to the URL specified. The method openConnection is called to create a new instance of a connection, but there is no connection actually made at this point. Set the type of request and the header values to pass: con.setRequestMethod("POST"); con.setRequestProperty("Accept", "application/json"); con.setRequestProperty("Content-Type", "application/json"); con.setRequestProperty("appKey", "80aab639-ad99-43c8-a482-2e1e5dc86a2d"); You can see that we are performing a POST request, passing in an Accept header, a Content-Type header, and a ThingWorx specific appKey header. Pass true into the setDoOutput method because we are performing a POST request; when sending a PUT request we would pass in true as well. When there is no request body being sent false can be passed in to denote there is no "output" and we are making a GET request.         con.setDoOutput(true); Create a DataOutputStream object that wraps around the con object's output stream. We will call the flush method on the DataOutputStream object to push the REST request from the stream to the url defined for POSTing. We immediately close the DataOutputStream object because we are done making a request.         DataOutputStream wr = new DataOutputStream(con.getOutputStream());     wr.flush();     wr.close();           The DataOutputStream class lets the Java SDK write primitive Java data types to the ​con​ object's output stream. The next line returns the HTTP status code returned from the request. This will be something like 200 for success or 401 for unauthorized.         int responseCode = con.getResponseCode(); The final block of this code uses a BufferedReader that wraps an InputStreamReader that wraps the con object's input stream (the byte response from the server). This BufferedReader object is then used to iterate through each line in the response and append it to a StringBuilder object. Once that has completed we close the BufferedReader object and print the response we just retrieved.         BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));     String inputLine;     StringBuilder response = new StringBuilder();     while((inputLine = in.readLine()) != null) {       response.append(inputLine);     }     in.close();     System.out.println(response.toString());    The InputStreamReader decodes bytes to character streams using a specified charset.         The BufferedReader provides a more efficient way to read characters from an InputStreamReader object.         The StringBuilder object is an unsynchronized method of creating a String representation of the content residing in the BufferedReader object. StringBuffer can be used instead in a case where multi-threaded synchronization is necessary.      Below is the block of code in it's entirety from the discussion above: public void sendPost() throws Exception {   String url = "http://127.0.0.1:80/Thingworx/Things/Thing_Name/Services/Service_to_Post_to";   URL obj = new URL(url);   HttpURLConnection con = (HttpURLConnection) obj.openConnection();   //add request header   con.setRequestMethod("POST");   con.setRequestProperty("Accept", "application/json");   con.setRequestProperty("Content-Type", "application/json");   con.setRequestProperty("appKey", "80aab639-ad99-43c8-a482-2e1e5dc86a2d");   // Send post request   con.setDoOutput(true);   DataOutputStream wr = new DataOutputStream(con.getOutputStream());   wr.flush();   wr.close();   int responseCode = con.getResponseCode();   System.out.println("\nSending 'POST' request to URL : " + url);   System.out.println("Response Code : " + responseCode);   BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));   String inputLine;   StringBuilder response = new StringBuilder();   while((inputLine = in.readLine()) != null) {   response.append(inputLine);   }   in.close();   //print result   System.out.println(response.toString());   }

In this blog I will be testing the SAPODataConnector using the SAP Gateway - Demo Consumption System.   Overview   The SAPODataConnector enables the connection to the SAP Netweaver Gateway through the ODdata specification. It is a specialized implementation of the ODataConnector. See Integration Connectors for documentation.   It relies on three components : Integration Runtime : microservice that runs outside of ThingWorx and has to be deployed separately, it uses Web Socket to communicate with the ThingWorx platform (similar to EMS). Integration Subsystem : available by default since 7.4 (not extension needed) Integration Connector : SAPODataConnector available by default in 8.0 (not extension needed)   ThingWorx can use OAuth to access SAP, but in this blog I will just use basic authentication.   SAP Netweaver Gateway Demo system registration   1. Create an account on the Gateway Demo system (credentials to be used on the connector are sent by email) 2. Verify that the account has access to the basic OData sample service : https://sapes4.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/   Integration Runtime microservice setup   1. Follow WindchillSwaggerConnector hands-on (7.4) - Integration Runtime microservice setup Note: Only one Integration Runtime instance is required for all your Integration Connectors (Multiple instances are supported for High Availability and scale).   SAPODataConnector setup   Use the New Composer UI (some setting, such as API maps, are not available in the ThingWorx legacy composer)     1.

Connectors allow clients to establish a connection to Tomcat via the HTTP / HTTPS protocol. Tomcat allows for configuring multiple connectors so that users or devices can either connect via HTTP or HTTPS.   Usually users like you and me access websites by just typing the URL in the browser's address bar, e.g. "www.google.com". By default browsers assume that the connection should be established with the HTTP protocol. For HTTPS connections, the protocol has to be specified explictily, e.g. "https://www.google.com"   However - Google automatically forwards HTTP connections automatically as a HTTPS connection, so that all connections are using certificates and are via a secure channel and you will end up on "https://www.google.com" anyway.   To configure ThingWorx to only allow secure connections there are two options...   1) Remove HTTP access   If HTTP access is removed, users can no longer connect to the 80 or 8080 port. ThingWorx will only be accessible on port 443 (or 8443).   If connecting to port 8080 clients will not be redirected. The redirectPort in the Connector is only forwarding requests internally in Tomcat, not switching protocols and ports and not requiring a certificate when being used. The redirected port does not reflect in the client's connection but only manages internal port-forwarding in Tomcat.   By removing the HTTP ports for access any connection on port 80 (or 8080) will end up in an error message that the client cannot connect on this port.   To remove the HTTP ports, edit the <Tomcat>\conf\server.xml and comment out sections like       <!-- commented out to disallow connections on port 80 <Connector port="80" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="20000" redirectPort="443" /> -->     Save and restart Tomcat. If opening Tomcat (and ThingWorx) in a browser via http://myServer/ the connection will fail with a "This site can’t be reached", "ERR_CONNECTION_REFUSED" error.   2) Forcing insecure connections through secure ports   Alternatively, port 80 and 8080 can be kept open to still allow users and devices to connect. But instead of only internally forwarding the port, Tomcat can be setup to also forward the client to the new secure port. With this, users and devices can still use e.g. old bookmarks and do not have to explicitly set the HTTPS protocol in the address.   To configure this, edit the <Tomcat>\conf\web.xml and add the following section just before the closing </web-app> tag at the end of the file:     <security-constraint>        <web-resource-collection>              <web-resource-name>HTTPSOnly</web-resource-name>              <url-pattern>/*</url-pattern>        </web-resource-collection>        <user-data-constraint>              <transport-guarantee>CONFIDENTIAL</transport-guarantee>        </user-data-constraint> </security-constraint>     In <Tomcat>\conf\web.xml ensure that all HTTP Connectors (port 80 and 8080) have their redirect port set to the secure HTTPS Connector (usually port 443 or port 8443).   Save and restart Tomcat. If opening Tomcat (and ThingWorx) in a browser via http://myServer/ the connection will now be forwarded to the secure port. The browser will now show the connection as https://myServer/ instead and connections are secure and using certificates.   What next?   Configuring Tomcat to force insecure connection to actually secure HTTPS connection just requires a simple configuration change. If you want to read more about certificates, encryption and how to setup ThingWorx for HTTPS in the first place, be sure to also have a look at   Trust & Encryption - Theory Trust & Encryption - Hands On

This document attached to this blog entry actually came out of my first exposure to using the C SDK on a Raspberry PI. I took notes on what I had to do to get my own simple edge application working and I think it is a good introduction to using the C SDK to report real, sampled data. It also demonstrates how you can use the C SDK without having to use HTTPS. It demonstrates how to turn off HTTPS support. I would appreciate any feedback on this document and what additions might be useful to anyone else who tries to do this on their own.

Introduction Oracle 12c release introduced the concept of multi-tenant architecture for housing several databases running as service under a single database, I'll try to address the connectivity and required configuration to connect to one of the Pluggable database running in the multi-tenant architecture. Multi-tenant database architecture in scope of ThingWorx External Data Source What is multi-tenant Database architecture ? Running multiple databases under a single database installation. Oracle 12c allows user to create one database called Container Database (CDB) and then spawn several databases called Pluggable Databases (PDB) running as services under it. Why use multi-tenant architecture? Such a setup allows users to spawn a new PDB as and when needed with limited resource requirements, easily administer several PDBs just by administering the container database - since all the PDBs are contained within a single database's tablespace structure, start and stop individual PDB leading to low cost on maintaining different databases - as the resource management is limited to one CDB. When to use multi-tenant architecture? In scenarios like creating PoCs, different test environments requiring external data storage, maintaining different versions of dataset, having this run in the multi-tenant architecture could help save time, money and effort. Create Container Database (CDB) Creation of a Container Database (CDB) is not very different from creating a non Container Database use the attached guide Installing Oracle Database Software and Creating a Database.pdf same is accessible online. Create Pluggable Database (PDB) Use the attached Multitenant : Create and Configure a Pluggable Database (PDB) in Oracle Database 12c PDF guide to create and plug a Pluggable Database into the Container Database created in previous step, same is accessible online Using above guide I have bunch of pluggable databases as can be seen below. I'll be using TW724 for connecting to ThingWorx server as an external datasource for following example Connect to a Pluggable Database(PDB) as external data source for ThingWorx Download and unzip the Relational Databases Connectors Extension from ThingWorx Marketplace and extract Oracle12Connector_Extension Import Oracle12Connector_Extension to the ThingWorx using Extension -> Import Create a Thing using OracleDBServer12 Thing Template , e.g. TW724_PDB_Thing Navigate to the Configurations for TW724_PDB_Thing to update the default configuration: JDBC Driver Class Name : oracle.jdbc.OracleDriver JDBC Connection String : jdbc:oracle:thin:@//oravm.ptcnet.ptc.com:1521/tw724.ptcnet.ptc.com Database Username : <UserName> Database Password : <password>   5. Once done save the entity Note: A PDB in a container database can be reached only as a service and not using the CDB's SID. In the above configuration TW724 is a PDB which can be connected to via it's service name i.e. TW724.PTCNET.PTC.COM Let's head to the Services tab for TW724_PDB_Thing to query and access the PDB data Creating Services to access the PDB as external database source for ThingWorx Once the configuration is done the TW724_PDB_Thing is ready for use. The queries remain the same as any other SQL query needed to access the data from Oracle. Service for creating a Table Once on the Services tab for the TW724_PDB_Thing click on Add My Service select the service handler as SQL Command to use following script to create a testTable1 in the PDB create table testTable1 (     id NUMBER GENERATED ALWAYS AS IDENTITY primary key,     col1 varchar2(100),     col2 number ) Note: GENERATED ALWAYS AS IDENTITY option is Oracle 12c specific and I included it here for the reason that with Oracle 12c the possibility to auto generate is now built in with that option simplifying the sequence generation when compared with older Oracle versions such as Oracle 11g. User creating table will need access right on creating table and sequence checkout the Oracle documentation on Identity for more on this. Service for getting all the data from the table Add another service with script Select * from testTable1 for getting all the data from the table Service for inserting data into the table Adding another service with script insert into testTable1 (col1, col2) values ('TextValue', 123)  will insert the data into the table created above Service for getting all tables from the PDB i.e. TW724 Using Select * from tab lists all the available tables in the TW724 PDB Summary Just a quick wrap up on how this would look visually refer to the following image. Since this is a scalable setup - given the platform having enough resources it's possible to create upto 252 PDBs under a CDB therefore 252 PDBs could be created and configured to as many things extending the OracleDBServer12 Thing. ______________________________________________________________________________________________________________________________________________ Edit: Common Connection Troubleshooting If you observe the error something like this Unable to Invoke Service GetAllPDBTables on TW724_PDB_Thing : ORA-01033: ORACLE initialization or shutdown in progress Ensure that the pluggable database, in this error TW724 (since this is what I created and used above in my services) is opened and accessible. If it's not opened use the command after logging in as sys/system (with admin rights) in CDB, which is ORCL in via SQL*Plus or SQL Developer or any SQL utility of your choice capable of connecting to Oracle DB and open the pluggable database using the command : alter pluggable database tw724 open;

  Connect a Raspberry Pi to ThingWorx using the Edge Micro Server (EMS).   Guide Concept   This project will introduce you to the Edge MicroServer (EMS) and how to connect your ThingWorx server to a Raspberry Pi device.   Following the steps in this guide, you will be able to connect to the ThingWorx platform with your Raspberry Pi. The coding will be simple and the steps will be very straight forward.   We will teach you how to utilize the EMS for your Edge device needs. The EMS comes with the Lua Script Resource, which serves as an optional process manager, enabling you to create Properties, Services, Events, and Subscriptions for a remote device on the ThingWorx platform.   You'll learn how to   Set up Raspberry Pi Install, configure and launch the EMS Connect a remote device to ThingWorx   NOTE: This guide's content aligns with ThingWorx 9.3. The estimated time to complete ALL parts of this guide is 30 minutes.    Step 1: Setup Raspberry Pi   Follow the setup instructions to get your Raspberry Pi up and running with the Raspberry Pi OS operating system. Ensure that your Pi has a valid Ethernet or Wifi connection. If your Pi is connected to a monitor/keyboard, run ifconfig from the Command Line Interface (CLI) to determine the IP address. If you are connecting remotely, probe your local network to find your Pi using one of these methods to determine the IP address. Log into your Raspberry Pi using the userid/password combination pi/raspberry.   Step 2: Install the EMS Download the MED-61060-CD-054_SP10_Microserver-Linux-arm-hwfpu-openssl-5-4-10-1509.zip attached here directly to the Raspberry Pi, or transfer it using a SFTP application such as WinSCP. After downloading the EMS zip file, unzip the archive in a suitable location on the Pi using the command below. Use the Tab key to automatically complete file names. unzip /MED-61060-CD-054_SP9_Microserver-Linux-arm-hwfpu-openssl-5-4-10-1509.zip After unzipping the distribution, a sub-directory named /microserver will be created inside the parent directory. Verify that microserver directory was created with the command ls -l   Switch into the microserver directory with the command cd microserver The microserver directory includes the following files.        File Name                    Description wsems An executable file that runs the Edge MicroServer luaScriptResource The Lua utility that is used to run Lua scripts, configure remote things, and integrate with the host system     Step 3: Create Application Key   In this step, you will be using the ThingWorx Composer to generate an Application Key. The Application Key will be used to identify the Edge Agent. The Application Key is tied to a user and has the same entitlements on the server.   Using the Application Key for the default User (Administrator) is not recommended. If administrative access is absolutely necessary, create a User and place the user as a member of the SecurityAdministrators and Administrators User Groups.   Create the User the Application Key will be assigned to.   On the Home screen of Composer click + New.   In the dropdown list, click Applications Key.   Give your Application Key a name (ie, MyAppKey). Set the User Name Reference to a User you created.   Update the Expiration Date field, otherwise it will default to 1 day. Click Save.   Step 4: Configure the EMS   The EMS consists of two distinct components that do slightly different things and communicate with each other. The first is the EMS which creates an AlwaysOn™ connection to the ThingWorx server. It binds things to the platform and automatically provides features like file transfer and tunneling.   The second is the Lua Script Resource (LSR). It is used as a scripting language so that you can add properties, services, and events to the things that you create in the EMS. The LSR communicates with your sensors or devices. The LSR can be installed on the same device as the EMS or on a separate device. For example, one LSR can be a gateway and send data from several different things to a single EMS.     Open a terminal emulator for the Raspberry Pi. Change directory to microserver/etc. cd microserver/etc Create a config.json file. EMS comes with two sample config files that can be used as a reference for creating your config.json file. The config.json.minimal file provides minimum and basic options for getting started. The config.json.complete provides all of the configuration options.   Create the config.json file in the etc folder. sudo nano config.json Edit the config.json file ws_servers - host and port address of the server hosting the ThingWorx Platform. If you are using a Developer Portal hosted server, your server hostname is listed on the dashboard. {"host":"<TwX Server IP>", "port":443} http_server - host and port address of the machine running the LSR. In this case it will be your localhost running on the raspberry pi. {"host":"127.0.0.1","port":8080, "use_default_certificate": true,"ssl": false, "authenticate": false} appKey - the application key generated from the ThingWorx server. Use the keyId generated in the previous step "Create Application Key". "appKey":"<insert keyId>" logger - sets the logging level for debugging purposes. Set to log at a DEBUG level. ("level":"INFO"} certificates - for establishing a secure websocket connection between the ThingWorx server and the EMS. A valid certificate should be used in a production environment but for debugging purposes you can turn off validation and allow self signed certificates. {"validate":false, "disable_hostname_validation": true} NOTE: To ensure a secure connection, use valid certificates, encryption and HTTPS (port : 443) protocol for establishing a websocket connection between the EMS and the ThingWorx Platform. 5. Exit and Save. ctrl x   Sample config.json File   Replace host and appKey with values from your hosted server.   { "ws_servers": [{ "host": "pp-2007011431nt.devportal.ptc.io", "port": 443 }], "appkey": "2d4e9440-3e51-452f-a057-b55d45289264", "http_server": { "host": "127.0.0.1", "port": 8080, "use_default_certificate": true, "ssl": false, "authenticate": false }, "logger": { "level": "INFO" }, "certificates": { "validate": false, "disable_hostname_validation": true } }     Click here to view Part 2 of this guide.

ThingWorx provides multiple ways to deliver your data to the server. You can choose from the C based EMS to your own C application that uses the C SDK as well as SDKs for many popular languages but what can you do if the device you want to collect data on is so small that it need a very lightweight data delivery method. Normally you would consider using the REST web service interface and writing your own custom client to post your data by there is an alternative, MQTT. MQTT is a lightweight protocol that can be used from an Arduino with an Ethernet Shield that can stream real time data directly to ThingWorx by installing the MQTT Marketplace Extension on your server. To learn more about how this kind of solution worked, I created this slide deck while building a hardware example: DeliveringArduinoDataToThingworx.pdf Hopefully, it can help others out who want to create this kind of solution as well.

Modbus is a commonly used communications protocol that allows data transfer between computers and PLCs. This is intended to be a simple guide on setting up and using a Modbus PLC Simulator with ThingWorx. ThingWorx provides Modbus packages for Windows, Linux and Linux ARM. The Modbus Package contains libraries and lua files intended to be used along with the Edge Microserver. Note: The Modbus package is not intended as an out of the box solution Requirements: ThingWorx Platform Edge Microserver Modbus Package Modbus PLC Simulator In this guide, a free Modbus PLC Simulator​ is used. Here is the direct download link for their v8.20 binary release. Configuring the EMS: The first step is to configure the EMS as a gateway. This is done via adding an auto_bind section in the config.json: "auto_bind": [ {     "name": "ModbusGateway",     "gateway": true }] This creates an ephemeral Thing that only exists when the EMS is running. The next step is to modify the config.lua to include the Modbus configuration. Copy over the contents of the etc folder of the Modbus Package over to the etc folder of the EMS. A sample config_modbus.lua is provided in the Modbus Package as a reference. The following code defines a Thing called MyPLC (which is a Remote Thing created on the Platform): scripts.MyPLC = {     file = "thing.lua",     template = "modbusExample",     identifier = "plc",     updateRate = 2000 } scripts.Thingworx = {     file = "thingworx.lua" } scripts.modbus_handler = {     file = "modbus_handler.lua",     name = "modbus_handler",     host = "localhost" } Adding 'modbusExample' to the above script enables the usage of the same located at /etc/custom/templates/. 'modbusExample' is a reference point for creating a script to add the registers of the PLC. The given template has examples for different basetypes. The different types of available registers are noted and referenced in the modbus.lua file available under /etc/thingworx/lua/. Setting up the PLC Simulator: Extract the mod_RSsim to a folder and run the executable. Since we are 'simulating' a PLC connection, set the protocol to Modbus TCP/IP. Change the I/O to Holding Registers (or any other relevant option), with the Address set to Dec. In the Simulation menu, select 'No animation' if you want to enter values manually or use 'Increment BYTES' to automatically generate values. This PLC Simulator will run at port 502. The Connection: With the EMS & luaScriptResource running, the PLC Simulator should have a connection to the platform with activity on the received/sent section. Now if you open the Remote Thing 'MyPLC' in the platform, the isConnected property (under the Properties section) should be true. (If not, go back to General Information, click on Browse in the Identifier section and select 'plc'). Go back to the Properties section, and click on Manage Bindings. Click on the Remote tab and the list of defined properties should appear. For example, the following code from the modbusExample.lua: properties.Int16HoldRegExample = {key="holding_register/1/40001?format=Int16", handler="modbus_handler", basetype="NUMBER"} denotes a property named Int16HoldRegExample at register 40001. The value at the address 40001 in the PLC Simulator should correspond with the value at the platform once this property is added and the Thing saved. If you are running into any errors when connecting with a Raspberry Pi, please take a look atDuan Gauche's follow up document/ guide - Using your Raspberry Pi with the Edge Microserver and Modbus

Hello! I have just written a tutorial on how to set up Lua to be run from the command line. As many already know, there is no good way to debug Lua scripts as they are used in package deployment in Software Content Manager, and building such a debugger is a vast and difficult undertaking. As an alternative, running small portions of code in the command line to ensure they will work as expected is one way to verify the validity of the Lua syntax prior to attempting a deployment. Here are the steps to set up Lua as a command line tool:   Grab the GCC compiler called TDM-GCC Run the exe file and follow the install instructions Remember the install directory for this, as the attached install script will need to be configured in a later step Default location in the install file is "C:\Program Files\TDM-GCC\" Note: leaving the "Add to PATH" selected will allow you to compile C code on the command line as well by typing "gcc" (this is not required for this set-up) Download the Lua source code ​This comes as a ".tar.gz" file, which can be tricky to extract in Windows Download 7zip for freeware which can unzip this type of archive Extract the Lua source code and navigate to the top level directory which should just contain one folder named like "lua-x.x.x" where the x's refer to the version Download and extract the attached zip file containing the build file Copy the "build.cmd" file from this to the top level directory of the Lua source code Modify the configuration as needed: Version number default is 5.3.4 (parameter is called lua_version) GCC install path default is "C:\Program Files\TDM-GCC\bin" (parameter is called lua_build_dir) Double click the "build.cmd" file A console window will appear with installation details If you see the following, then it worked successfully: The "lua\" directory will be created in the same folder as the "build.cmd" file Copy the "lua\" directory to "C:\Program Files\" Open "Computer" > "System Properties" > "Advanced system settings" Click "Environment Variables" > "New..." Call the variable "LUA" and make the value "C:\Program Files\lua\bin" Find the "Path" variable and click "Edit..." At the end of what is already there (do NOT delete anything that is already there), add "%LUA%" (make sure there is a ";" between the previous path and this entry) Click "Ok" Open a new command prompt (has to be new to load the new path) and type "lua" to see if it works Example syntax test from Lua command line:   I hope this is helpful to people! Let me know if you have any questions!

  Leverage the REST API to create Things, modify Properties, execute Services and more.   GUIDE CONCEPT   This project will introduce you to the REST API utilized by the ThingWorx platform.   Following the steps in this guide, you will be able to connect to the ThingWorx platform and make REST calls to call Services, update Properties, and perform a number of actions for your IoT applications.   We will teach you how to use the ThingWorx REST API to create a more robust application. With the REST API you can leverage the full power of the ThingWorx Foundation server with simple HTTP requests. The REST API can easily be explored using a command line tool such as curl, a browser plugin like Postman, or any preferred programming language.   YOU'LL LEARN HOW TO   Create new Things on a ThingWorx Foundation Server Add Properties to Things Access Property values Execute custom Services   NOTE: The estimated time to complete ALL 4  parts of this guide is 30 minutes.      Step 1: REST API Design   Almost every Entity and Service of ThingWorx can be accessed through the REST API. This step will review some points that are common to all ThingWorx REST API calls.   REST API Syntax   The endpoint URLs used by the REST API follow the consistent pattern shown in the diagram below.   The following table describes the individual pieces of the URL for the REST API calls.   Term Description Optional/Required? http method GET, PUT, DELETE, POST required scheme http, https required host server IP address where ThingWorx is running required port port on which the Web Server is listening for requests (default is 80) optional entity collection One of the built-in entity collection types proprietary to ThingWorx required entity name that identifies a specific characteristic required characteristic collection Names such as Property Definition, Properties VTQ, ThingName, and Service Definition optional characteristic name of the Service or Property on which to execute optional accept header format of HTTP content being requested; must be application/json or text/xml or text/html optional content type header format of HTTP content being provided; must be application/json, text/csv or text/html required content   optional query parameters   optional   Requests   The ThingWorx REST API uses HTTP request verbs in ways common to many REST APIs:   GET to retrieve information POST for both creating a new entity and executing a service DELETE to remove a Thing or Property PUT to change the value of an existing entity When a REST API request requires parameters to be sent, the Content-Type header must be set to match the format of the request body.   Discovering and using Services requires using a dedicated URL. To list available Services and see their definitions, issue a GET to   ``` <server_ip:port>/Thingworx/Things/<name of thing>/ServiceDefinitions ``` In order to execute a listed Service issue a POST to   ``` <server_ip:port>/Thingworx/Things/<name of thing>/Services/<service name> ```   NOTE: The Content-Type header of a POST that executes a Service must always be set to application/json or text/xmleven if the service does not take any parameters and no content is being sent.   Responses   The following tables describe the valid Accept and Content-Type header values when making a REST API calls.   Accept Headers   If the request sends either an invalid Accept header, or no Accept header is supplied, the default response will be in text/html format.   Value Syntax JSON application/json XML text/xml HTML text/html (or omit Accept header) CSV text/csv   Content Type Headers   A Content-Type header indicating the format of data sent to ThingWorx, is required. Some POST requests require a content type header even when no data is being sent.   Value Syntax JSON application/json XML text/xml     Step 2: REST Client   In order to make calls to any REST API you need a client software. A web browser can be used to make some GET calls, but you must install extensions to modify headers or to make POST or PUT calls.   Client software options include:   cURL is a venerable command line tool and library that is a Swiss Army Knife of dealing with web requests. And like an old Swiss Army Knife you can make it work but you might wind up hurting yourself.   Httpie is a modern command line tool with easy to use, intuitive options. Server responses are shown in color with easy to read formatting. The examples will be given as HTTPie commands.   NOTE: The following steps in this guide use Httpie as the client software.     Step 3: Create Application Key   In this Quickstart, you will use ThingWorx Composer to generate an Application Key. A device must be authenticated to send data to, or recieve data from ThingWorx. One of the most common authentication methods used with ThingWorx is by using a security token called an Application Key or appKey. These tokens are associated with a particular user and have the same permissions as that user.   Create an Application Key   On the Home screen of Composer click + New. In the dropdown list, click Applications Key.   Give your Application Key a name (ie, MyAppKey). Set the User Name Reference to a User you created. Update the Expiration Date field, otherwise it will default to 1 day. Click Save.   A Key ID has been generated and can be used to make secure connections.   BEST PRACTICE: We recommend you create separate keys for every connected device, User or system. This allows better security in case of situations where you may need to revoke access from one of them.     Step 4: Create New Thing   A Thing is a basic building block used to model applications in the ThingWorx Foundation Server. All Things are based on a Thing Template, either a built-in system template or a custom Template that was previously created. With the REST API, you can create, modify, list, and delete Things. After a Thing has been created by using an API call, it must be enabled and restarted with additional API calls before it can be used.   Required Parameters   AppKey created by your ThingWorx server A name for the new Thing The name of a valid ThingTemplate that will be used to create the new Thing Request   An HTTP POST request to ThingWorx is assembled from 3 components: a URL A POST body Authentication credentials A request to ThingWorx can be made only after these 3 components are properly configured.         1.  Construct the URL.   Create a new Thing by making an HTTP POST to the endpoint.   <server_ip:port>/Thingworx/Resources/EntityServices/Services/CreateThing NOTE: The server_ip is the ip address of your ThingWorx Core server.        2. Required POST body parameters.   Send the name of the Thing and the name of the ThingTemplate that will define the new thing in the body of the POST as a JSON object. For example, the JSON object below will create a new Thing named SomeTestThing using the system template GenericThing. { "name": "SomeTestThing", "thingTemplateName": "GenericThing" }   TIP: When creating Things that will be used with the REST API, use the GenericThing ThingTemplate or a ThingTemplate based GenericThing. A RemoteThing should only be used with devices that make an AlwaysOn™ connection to a ThingWorx server using the Edge MicroServer or one of the AlwaysOn™ SDKs.        3. Authenticate the Request.   All API requests to the ThingWorx server must be authenticated either with a username and password or with an appKey. For this example we will authenticate by passing the appKey as a URL query string parameter. The parameter appKey is recognized by the ThingWorx server as an authentication credential in requests, it can be passed either as a URL query string parameter. .../CreateThing?appKey=64b87... , or as request header appKey: 64b87... Refer to Step 13: Authentication Tags for an overview of different authentication methods. Response   A successful call to the CreateThing service does not return any content in the body of the response, only an HTTP 200 is returned.   Examples HTTPie example:   http -v http://52.201.57.6/Thingworx/Resources/EntityServices/Services/CreateThing appKey==64b879ae-2455-4d8d-b840-5f5541a799ae name=SomeTestThing thingTemplateName=GenericThing   The Content-Type header does not appear in the sample HTTPie call because HTTPie sets the Accept and Content-type request headers to application/json by default.   WARNING for other HTTP clients: Most HTTP clients do not set a Content-Type header by default, without this header set the server will return an error message. The POST request to the CreateThing endpoint has a JSON body so the header must be set to match the format of the request body.   cURL example   curl -v -H "Content-Type: application/json" -X POST -d '{"name": "SomeTestThing","thingTemplateName": "GenericThing"}' http://52.201.57.6/Thingworx/Resources/EntityServices/Services/CreateThing?appKey=d0a68eff-2cb4-4327-81ea-7e71e26bb645 Note: cURL explicitly sets the Content-Type header to application/json.     Validate   The Thing you just created is now available in the ThingWorx Composer, however before anything else can be done with your new Thing through the REST API it must be enabled and started. Follow these steps to validate that the new Thing has been created and enabled.   From the home page of Composer, click Things, select the name of the Thing you just created, then click General Information.   NOTE: You will see the Active checkbox is not checked indicating this Thing is not Enabled.       2. Execute EnableThing Service.   To enable your newly created Thing, make an HTTP POST to the endpoint below. Substitute <name of Thing> with the actual name of the Thing you created. No body is required in the POST, however, the Content-Type header of a POST that executes a Service must always be set to application/json or text/xml even if the service does not take any parameters and no content is being sent. No body is returned upon success, only an HTTP 200 response code. <server_ip:port>/Thingworx/Things/<name of Thing>/Services/EnableThing HTTPie example   http -v -j POST http://52.201.57.6/Thingworx/Things/SomeTestThing/Services/EnableThing appKey==64b879ae-2455-4d8d-b840-5f5541a799ae         3.  Confirm new Thing is Enabled.   To update the General Information section of your new Thing and confirm the Active checkbox is now checked, refresh the page with the browser or close and re-open your Thing.         4. Restart your Thing.   After a Thing is created and whenever any changes are made to its structure, the Thing has to be restarted. Start you new Thing by making a HTTP POST to the endpoint below. Substitute <name of Thing> with the actual name of the Thing you created. No body is required in the POST, however, the Content-Type header of a POST that executes a Service must always be set to application/json or text/xml even if the service does not take any parameters and no content is being sent. No body is returned upon success, only an HTTP 200 response code. <server_ip:port>/Thingworx/Things/<name of Thing>/Services/RestartThing HTTPie example:   http -v -j POST http://52.201.57.6/Thingworx/Things/SomeTestThing/Services/RestartThing appKey==64b879ae-2455-4d8d-b840-5f5541a799ae     Click here to view Part 2 of this guide

  GUIDE CONCEPT   This guide introduces connecting an Allen-Bradley PLC to ThingWorx Kepware Server.   YOU'LL LEARN HOW TO   Create and run a simple ladder logic application on an Allen-Bradley PLC Connect the PLC to ThingWorx Kepware Server   NOTE: The estimated time to complete this guide is 30 minutes.      Step 1: Learning Path Overview   Assuming you are using this guide as part of the Rockwell Automation Learning Path, then you have now completed each of the following installations:        1. Connected Components Workbench       2. ThingWorx Kepware Server       3. ThingWorx Foundation (for Windows)   In this continued step, you'll now connect an Allen-Bradley PLC to Connected Components Workbench and then to ThingWorx Kepware Server.   In a later guide, we'll propogate that information further from ThingWorx Kepware Server into ThingWorx Foundation.   NOTE: Both Rockwell Automation's Connected Components Workbench and ThingWorx Kepware Server are time-limited trials. If significant time has passed while persuing this Learning Path, you may need to reinitialize them. Consult the Troubleshooting step of this guide for more information.       Step 2: Setup PLC   This guide uses an inexpensive Allen-Bradley Micro820 PLC as a demonstration.   ThingWorx Kepware Server offers drivers for hundreds of devices, making this step the only one that contains device-specific instructions.   Read and understand installation instructions before making any electrical connections to the PLC.   1. Connect the postive lead of a 24V power supply along with a 6" test lead to Terminal 1 of the output terminal block.   2. Connect the negative lead of the power supply to Terminal 2.     3. Confirm the test lead is secure from making contact with anything conductive; it will be  connected to +24V. Power on the supply and confirm the LEDs briefly light.       4. Carefully touch the test lead to the Input 1 terminal and confirm the indicator LED for Input 1 turns on.     5. Power off the supply before continuing to the next step.       Step 3: Create PLC Project   In this step, you will create a simple PLC application. This application will connect to a ThingWorx Mashup in subsequent guides in the Learning Path.    1. After opening Connected Components Workbench, click New... in the Project section.   2. Enter ThingWorxGuide in the Name field and click Create.   3. Browse to the PLC model you are using and click Select, then Add to Project.     4. Right-click Program, then left-click Add > New LD: Ladder Diagram     5. Double-click Prog1 to open the ladder window.     Ladder Logic   You will create a simple application that will turn on output 2 when there is a signal on input 2.    1.. Right-click in the box to the left of the rung, hover over Insert Ladder Elements, then click on Direct Coil   .     2. Click the I/O - Micro820 tab towards the right and select an output coil - this guide uses _IO_EM_DO_02. Then click OK                  3. Add an input contact by right-clicking in the box to the left of the rung, hover over Insert Ladder Elements, then click on Direct Contact.   4. Click the I/O - Micro820 tab and scroll down to select an input - this guide uses _IO_EM_DI_02. Then click OK.        5. The program window should now look like this:     Upload   Next, you will propagate the program to the PLC.   1. Secure the test lead then apply power to the PLC.   2. Connect an ethernet cable directly between the PLC and your Windows computer.   3. Click Device > Connect to connect to the PLC; a pop-up will appear saying the project does not match the program in the controller.     NOTE: When either your PLC or computer are restarted, they may be assigned a new IP address, requiring you to reconfigure the connection. Click the tab labled with your PLC, then click the pencil icon next to connection path, click Browse, expand the Ethernet driver, highlight the active controller, and click OK. Click Close and then Connect.       4. Click Download current project to the controller   5. Confirm overwriting any program in the controller by clicking Download.   6. After your project is downloaded, run it on the controller by clicking Yes.     7. Touch the test lead to the I-02 terminal, and your program will turn on the #2 output. You can confirm your project is working by both hearing the soft click from the PLC and seeing the output indicator turn on.       Step 4: Configure ThingWorx Kepware Server   Now that you have a simple project running on the PLC, you need to configure ThingWorx Kepware Server to monitor it.   1. Open ThingWorx Kepware Server, right-click on Connectivity, and click New Channel.   2. Select Allen-Bradley Micro800 Ethernet from the drop-down, then click Next.       3.

Introduction The Edge MicroServer (EMS) and Lua Script Resource (LSR) are Edge software that can be used to connect remote devices to the ThingWorx platform. Using a Gateway is beneficial because, this will allow you to run one instance of the EMS on a server and then many instances of the LSR on different devices all over the world. All communication to the platform will be handled by this one EMS Gateway server. The EMS Gateway can be set up in two different types of scenarios: Self-Identifying Remote Things and Explicitly defined Remote Things​. The scenario I'm going to discuss below will involve explicitly defined Remote Things, a ThingWorx server, an EMS, and a LSR. We will need at least 1 server to run the ThingWorx platform and EMS, but these can always be on separate servers as well. We will also need some other machine or device that will run the LSR. Visit the support downloads page to find the latest EMS releases. The LSR is contained within the EMS download. You can also navigate to the Edge Support site to read more about the EMS and LSR oif this is the first time you have ever configured one. The "ThingWorx WebSocket-based Edge MicroServer Developer's Guide" is also provided inside of the zip file that contains the EMS for further information. Setting up the EMS Once we have obtained the EMS download from the support site (see the section above for links) we can begin creating our config.json file. The image below is a working config.json file for using the EMS as a Gateway. The settings in here are particular to my personal IP addresses and Application Key, but the concept remains the same, and I will go into further detail on the necessary sections, below the image. ws_servers The host and port parameters are always set to the IP address and port that the ThingWorx platform is being hosted on When the EMS and ThingWorx platform are on the same server, "localhost" can be used instead of an IP address appKey The appKey section is the value of an Application Key in the ThingWorx platform that should be used for the authentication of the EMS to the platform An Application Key will need to be created and assigned a user with proper priveledges prior to authenticating certificates The certificates section should be validating and pointing to proper certificates, but in the example above I am not validating any certificates for the sake of simplicity More can be read about the certificates sections here logger The logging section is out of scope of this article, but further reading on ​logger​ configurations can be found here The section in the example above will work for basic logging needs http_server The http_server section configuration parameters will tell the EMS what host and port to spin up a server on and if there is authentication necessary by any LSRs trying to connect The LSR has settings that will explicitly call out whatever value is set to the host and port in this section, so make sure to set these to an open port that is not in use or blocked behind a firewall Further reading on the http_server section can be found here auto_bind You can see above that there are two objects defined in the auto_bind section. One of these is binding the EMS to an EMSGateway Thing in the platform called "EdgeGateway" and the other is defined in the config.lua file for the LSR The gateway parameter is set to true only in the object, "EdgeGateway", that is being used for the EMS to bind to The host and port defined for the "OtherEdgeThing" should point to the port and IP address that the LSR is running on in the other device By default, the LSR runs on port 8001, but you can always double check the listening port by finding the Process Identification (PID) number of the luaScriptResource.exe and then matching the PID to the corresponding line item in the output of netstat -ao command in a console window The protocol can be set to "http" in an example application, but make sure to use "https" when security is of concern All further reading on the sections of the config.json file can be found in the config.json.complete file included with the EMS download and on the Edge Help Center under the "Creating a Configuration File" section and the "Viewing All Options" section. Setting up the LSR In this example, the LSR is going to run on a separate server and point to the EMS server. Below is a screenshot of two very important additions (rap_host and rap_port) to the default config.lua file: rap_host The rap_host field should be set to the IP address where the EMS is hosted rap_port The rap_port field should be set to the port parameter defined in the config.json http_server section script_resource_host The ​script_resource_host​ field must be set to ensure that the EMS will know what IP address to communicate with the LSR at scripts.OtherEdgeThing This line is necessary to identify what the name of the LSR is that will register with the EMS to bind to the platform "OtherEdgeThing" can be changed to anything, but make sure that the auto_bind section in the config.json aligns with what you've defined in the config.lua file at this line Running the EMS and LSR Now that we have configured the LSR and EMS to point to each other and the platform we can try running both of these applications to make sure we are successful. Make sure the ThingWorx platform is running Create a RemoteThing with the name given in the auto_bind section for the LSR we are connecting Create an EMSGateway with the name given in the auto_bind section for the EMS as a Gateway to bind to Start the EMS This can be done by double clicking the wsems.exe when in Windows, running it as a service, or running it directly from the command line Start the LSR This can be done by double clicking the luaScriptResource.exe when in Windows, running it as a service, or running it directly from the command line Navigate to the ThingWorx platform and make sure that the Things you have created are connected Do this by navigating to the Properties menu option and refreshing the isConnected property You should be able to browse remote properties and services for each bound RemoteThing, and this means you have successfully setup the EMS as a Gateway device to external LSR applications running on remote devices Any further questions about browsing remote properties or other configuration settings in the .config files is most likely addressed in the Edge Help Center under the EMS section​, and if not, feel free to comment directly on this document.

Hello everyone,   Following a recent  experience, I felt it was important to share my insights with you. The core of this article is to demonstrate how you can format a Flux request in ThingWorx and post it to InfluxDB, with the aim of reporting the need for performance in calculations to InfluxDB. The following context is renewable energy. This article is not about Kepware neither about connecting to InfluxDB. As a prerequisite, you may like to read this article: Using Influx to store Value Stream properties from... - PTC Community     Introduction   The following InfluxDB usage has been developed for an electricity energy provider.   Technical Context Kepware is used as a source of data. A simulation for Wind assets based on excel file is configured, delivering data in realtime. SQL Database also gather the same data than the simulation in Kepware. It is used to load historical data into InfluxDB, addressing cases of temporary data loss. Once back online, SQL help to records the lost data in InfluxDB and computes the KPIs. InfluxDB is used to store data overtime as well as calculated KPIs. Invoicing third party system is simulated to get electricity price according time of the day.   Orchestration of InfluxDB operations with ThingWorx ThingWorx v9.4.4 Set the numeric property to log Maintain control over execution logic Format Flux request with dynamic inputs to send to Influx DB  InfluxDB Cloud v2 Store logged property Enable quick data read Execute calculation Note: Free InfluxDB version is slower in write and read, and only 30 days data retention max.     ThingWorx model and services   ThingWorx context Due to the fact relevant numeric properties are logged overtime, new KPIs are calculated based on the logged data. In the following example, each Wind asset triggered each minute a calculation to get the monetary gain based on current power produced and current electricity price. The request is formated in ThingWorx, pushed and executed in InfluxDB. Thus, ThingWorx server memory is not used for this calculation.   Services breakdown CalculateMonetaryKPIs Entry point service to calculate monetary KPIs. Use the two following services: Trigger the FormatFlux service then inject it in Post service. Inputs: No input Output: NOTHING FormatFlux _CalculateMonetaryKPI Format the request in Flux format for monetary KPI calculation. Respect the Flux synthax used by InfluxDB. Inputs: bucketName (STRING) thingName (STRING) Output: TEXT PostTextToInflux Generic service to post the request to InfluxDB, whatever the request is Inputs: FluxQuery (TEXT) influxToken (STRING) influxUrl (STRING) influxOrgName (STRING) influxBucket (STRING) thingName (STRING) Output: INFOTABLE   Highlights - CalculateMonetaryKPIs Find in attachments the full script in "CalculateMonetaryKPIs script.docx". Url, token, organization and bucket are configured in the Persitence Provider used by the ValueStream. We dynamically get it from the ValueStream attached to this thing. From here, we can reuse it to set the inputs of two other services using “MyConfig”.   Highlights - FormatFlux_CalculateMonetaryKPI Find in attachments the full script in "FormatFlux_CalculateMonetaryKPI script.docx". The major part of this script is a text, in Flux synthax, where we inject dynamic values. The service get the last values of ElectricityPrice, Power and Capacity to calculate ImmediateMonetaryGain, PotentialMaxMonetaryGain and PotentialMonetaryLoss.   Flux logic might not be easy for beginners, so let's break down the intermediate variables created on the fly in the Flux request. Let’s take the example of the existing data in the bucket (with only two minutes of values): _time _measurement _field _value 2024-07-03T14:00:00Z WindAsset1 ElectricityPrice 0.12 2024-07-03T14:00:00Z WindAsset1 Power 100 2024-07-03T14:00:00Z WindAsset1 Capacity 150 2024-07-03T15:00:00Z WindAsset1 ElectricityPrice 0.15 2024-07-03T15:00:00Z WindAsset1 Power 120 2024-07-03T15:00:00Z WindAsset1 Capacity 160   The request articulates with the following steps: Get source value Get last price, store it in priceData _time ElectricityPrice 2024-07-03T15:00:00Z 0,15 Get last power, store it in powerData _time Power 2024-07-03T15:00:00Z 120 Get last capacity, store it in capacityData _time Capacity 2024-07-03T15:00:00Z 160 Join the three tables *Data on the same time. Last values of price, power and capacity maybe not set at the same time, so final joinedData may be empty. _time ElectricityPrice Power Capacity 2024-07-03T14:00:00Z 0,15 120 160 Perform calculations gainData store the result: ElectricityPrice * Power _time _measurement _field _value 2024-07-03T15:00:00Z WindAsset1 ImmediateMonetaryGain 18 maxGainData store the result: ElectricityPrice * Capacity lossData store the result: ElectricityPrice * (Capacity – Power) Add the result to original bucket   Highlights - PostTextToInflux Find in attachments the full script in "PostTextToInflux script.docx". Pretty straightforward script, the idea is to have a generic script to post a request. The header is quite original with the vnd.flux content type Url needs to be formatted according InfluxDB API     Well done!   Thanks to these steps, calculated values are stored in InfluxDB. Other services can be created to retrieve relevant InfluxDB data and visualize it in a mashup.     Last comment It was the first time I was in touch with Flux script, so I wasn't comfortable, and I am still far to be proficient. After spending more than a week browsing through InfluxDB documentation and running multiple tests, I achieved limited success but nothing substantial for a final outcome. As a last resort, I turned to ChatGPT. Through a few interactions, I quickly obtained convincing results. Within a day, I had a satisfactory outcome, which I fine-tuned for relevant use.   Here is two examples of two consecutive ChatGPT prompts and answers. It might need to be fine-tuned after first answer.   Right after, I asked to convert it to a ThingWorx script format:   In this last picture, the script won’t work. The fluxQuery is not well formatted for TWX. Please, refer to the provided script "FormatFlux_CalculateMonetaryKPI script.docx" to see how to format the Flux query and insert variables inside. Despite mistakes, ChatGPT still mainly provides relevant code structure for beginners in Flux and is an undeniable boost for writing code.
