IoT & Connectivity

Hello all, I have been following this tutorial of sorts to connect Thingworx to external databases. https://developer.thingworx.com/en/resources/guides/external-databases/external-database-read I'm using a MySQL database. the problem arises when I am trying to run a javascript based query service. I am not getting any results to the query when I run the service and the reason is quoted as  " Must have a datashape defined to add rows".

In Function: Resources["ContentLoaderFunctions"].Delete(params); https://support.ptc.com/cs/help/thingworx_hc/thingworx_7.0_hc/index.jspx?id=ID4065119192&action=show There is missing "content" property, so it's not possible to send some DELETE requests, eg here:  https://developer.spotify.com/console/delete-playlist-tracks/ Is there some other way to send request body by DELETE method?  

Hello,   I have noticed that under the "Users Logged In" Monitor page that there are several instances of Administrator being logged in.   I found this page that briefly explains why (https://www.ptc.com/ru/support/article/CS261404) but it did not provide me with any guidance on how to close out of the duplicate sessions. I tried pressing the logout button in the composer, closing out of the browser, and restarting my computer but when I log back in and check there are still multiple sessions for "Administrator" on the "Users Logged In" page.   We have noticed significant slow downs on our web server because of the CPU usage of duplicate logins. Can someone provide me with instruction on how to end the duplicate sessions and prevent them in the future?  

here is a problem. in my design, there are 30 charts in one mashup page. But it is so squeeze and it is hard to see data in details. May I know if I click one small chart and pop up a entire chart for each.

Is there a way to add a local service with its JS code for a Thing using TWX REST APIs?

A user can make a direct REST call to Thingworx platform, but when it comes to a website trying to make a REST call. The platform server blocks the request as it is a Cross-Origin request. To enable this feature, the platform server needs to allow Cross-Origin request from all/specific websites. Enabling Cross-Origin request can be done by adding CORS filter to the server.CORS (Cross-Origin Resource Sharing) specification enables the cross-origin requests from other websites deployed in a different server. By enabling CORS filter, a 3rd party tool or a website can retrieve the data from Thingworx instance. Follow the below steps inorder to update the CORS filter:Update web.xml file (located in $CATALINA_HOME/conf/web.xml)For Minimal Configurations, add the below code:<filter><filter-name>CorsFilter</filter-name>  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class></filter><filter-mapping>  <filter-name>CorsFilter

Hi, I have a small issue with the fileupload widget which is occurring across a number of versions of Thingworx (8.2.4 & 8.2.8). The upload itself is working correctly but the 'No file chosen' property of the widget doesn't update when I select a file for uploading. As I say, the actual upload works fine and the file is uploaded to the correct location in the repository     does anyone else have this issue, and if so have you figured out a fix, work around?   Thanks, K  

Hi Folks,   Anyone came across similar requirement,please respond.   I have devices data(CNC machine,etc) fetched to Influx Database. And want to display OEE reports and thought of Manufacturing Apps to achieve the same. Is there any tutorials or guides to integrate Influx DB with Thingworx and develop Mashups as per requirement.   Thanks, Tarun

Hi,   I see that some data table things I create doesn't have the Mashup option to view the content of it. Surprisingly, few data table things get that option. Am I doing any mistake while creating the Data Table (I am using the same Data Table Thing Template as Base thing template while creating the data tables and that Thing Template also has the DatatableEditor as its Home Mashup) ? Licensed ThingWorx version: 8.3.3

Hi Everyone,   I have a webframe in mashup. From that webframe I want to access ThingWorx Services through REST API's. Currently it is asking for authentication. But is there any other way to access API's without authentication or app key from webframe? Or is there any way to authenticate if I send username and password as Query parameters in webframe URL?   

Is there a possibility to add another status beside the 6 default ones in the configuration and setup app ?  I can only find the customization of the expressions in the guide.   Or can i rename the "UNPLANNED_DOWNTIME" in e.g. "ERROR"  ?

Hi I'm looking for a way to set a textbox widget to be ignored when a value is not entered into it in a mashup.  Right now it sends a blank value to an input on a service and I need it to not send anything when nothing is entered.  A numeric entry box doesn't send anything when nothing is entered and I'd like the textbox to do the same.

Hi All Would like to assign a source URL to Link widget by Thingworx service. Can you please let me know how to access a Link widget and its properties from Thingworx service.    Appreciate your help. Thanks.

Hello Developers, We are facing some problems trying to connect the Siemens power monitoring device "PAC3200" with KEPserverEX 6.5, using the Modbus TCP/IP protocol, the basic configuration are done using its manuals (attached) but we still have a Bad Quality in the tags. This is basic configuration for the device:   Device Configuration For the tag: Tag Configuration Just a tag example from the PAC manual:PAC3200 Variable This is a variable that we can use the function code 0x03 and 0x04 (page 40). I tried to use the address 400001, 30001, 300001, disable the zero-based-addressing, modbus-byte-order and nothing works.  Note: I can ping the device with no issues.   Kind Regards.        

I have a textbox, and the text is bound to a validator widget. The validator widget checks to make sure that the input is not null/empty, and if not, it runs a service. Everything works as expected, but the validator only runs when the user clicks off the textbox (I have no enter/submit button).    I want to rework this so that the validator runs without the user clicking off - or, make this automatic some how.    Any thoughts?

I am not getting any extension file for operator advisor. please guide me for the same.

Hello everyone!   Testing ADO Service, I encountered the following problem. Having created a new service of SQL-query type I try to make a SELECT — but any of the written options leads to this:     Is the problem in the wrong team or the table is considered generally empty? Judging by the IsConnected property set to true and the screenshot below, ThingWorx sees the tables and columns of my database.    

Hi, For the combo box with display values with special characters, row Selection does not work Exemple:  It's not possible to select Test &, i tried to replace "&" by: Escape sequence, HTML numeric code and HTML named code, nothing worked.

Dear,We have a specail case to handle thingwox with datastax.I just want to add measure data set into thingworx and cassandra but data include several measured data such as measured by manual and then this data should be inserted middleware database.Thingworx take this data after updated in kepware through interanl middleware.It means there is two types of times, one is measued time by manual and another is thingworx create time.In this case thingworx insert measure data in storing time instead of measure time.But customer want to see data with measure time. But thingworx insert data with created time.We are about to change createdate but this should be primary key and cannot be changed.How should we resolve this problem? Otherwise do we get hiw to change primary key in Cassandra?

Hi There, we are facing lot of problems when upgrading from 7.3.8 to 8.4.3. One of which is a problem with making requests from ThingWorx to Apache servers with LoadText() This Issue has been raised before and it is marked as Solved. I think it is not solved, because option "ignoreSSLErrors" has to prevent service to fail.  Apache servers are using self signed certs and we cannot change them.  We need to solve this by ignoring all SSL problems with response handling.  Needless to say this is a PROD environment for a very big customer of ours and PTCs.

Hello All, What do you follow as coding best practices within Thingworx Platform. I see that there are Thingworx Modeling best practices videos available. Can you share what you do as code review best practice in Thingworx?   Preeti
