IoT & Connectivity

I've been playing around with Thingworx 8.4 Trial and for some reason I'm unable to set the Data Fields using using QueryPropertyHistory Data.  They just show up as blank and it seems no matter what I do it remains this way.  I've imported this from 8.3 and it was working correctly in that version.  I've created a new Thing and tried to use it's data and I still keep getting the same issue.  Not sure if it's another permissions issue but anyone have any ideas?

I have been trying to install Thingworx platform 8.3, and when I followed the steps in the guide, I got a 503 Service Unavailable error. Apache tomcat is running.

I am trying to bind a Menu object to a collection widget and am having some issues passing fields from the Menu's GetMenuItems service down to the mashup parameter of the sub-mashup.   Please see the images below: Service is binding with All Data Collection widget binding, showing connection to sub-mashup "title" to "title" mapping Sub-mashup parameter config   Mashup parameter bound to label Rendered mashup. Shows two records returned from service, and one selected mashup below in the collection widget. Errors shown. 14:58:24 ERROR - exception executing binding {"Id":"22df3b4e-f5b6-4477-bec3-7ad102aa949d","SourceArea":"Mashup","SourceSection":"","SourceId":"mashup-root","TargetArea":"UI","TargetSection":"","TargetId":"label-3","PropertyMaps":[{"SourceProperty":"title","SourcePropertyBaseType":"STRING","TargetProperty":"Text","TargetPropertyBaseType":"STRING"}],"isBoundToSelectedRows":false,"SourceDetails":"AllData"} Exception: Cannot read property 'getProperty' of undefined

I have 2 mashups and i need to switch and display each in a time interval of 5 mins. How can i achieve this in thingworx?  Can this be achieved using Timer? If so, can you please provide some examples? Also please share any other methods used to achieve the same

Hi ,  The method updateProperty is a callback method for a customized widget , it works if bind a Thing's service result to a field .     However ,  it does NOT work if bind a dynamic ThingTemplate service result,  updateProperty is not  call in this case .  Is this a bug ?    Regards, Sean

Hi all,   I have a question about mashup's resolution. What happens with me it is the follow:   When I open my mashup in my smartphone it does not adjust automatic in the screen. I am using the mashup of type "responsive (advanced)"   Regards.

Hello    I have set up Thingworx environment with Manufacturing Apps and installation went fine. However after adding Wokflow Builder - Console log fails to display and I have message in logs [message: Unable to Invoke Service QueryDataTableEntriesLocalized on PTC.FactoryConsole.DataTable : Invalid format: "permanent"]   For me it looks like the problem is that I have in CurenntLicenseInfo THINGWORX_FOUNDATION twx_utilities_workflows uncounted uncounted 0 8.1 permanent As a expiration date   Did anyone encountered that issue ?

     Hi,everyboby.I have completed the Raspberry Pi Quickstart documentation.     I'm able to use EMS to send raspberry voltage and other data uploaded to the thingworx platform.   Now I want to read the data on the sensor that placed on the raspberry through use of EMS,and then  will be the sensor data uploaded to the Thingworx platform .Can you recommend several learning documents or examples?Thanks!

Hi,   I wonder how to enable a manager to change/reset password of his members?   My Bests, Hung Tran

Dear community,    I'm trying to get better at visualising data and getting to know the different data visualisation widgets in ThingWorx.  I'm also looking a bit arround to demo's to get some inspiration, and I came accross a widget I can't find anywhere else. I'm talking about the widget-progress-bar in the image below. It shows a real smooth progress bar which you can display by a bar, gauge or a circle.    Has anyone ever seen this widget? I can't find the widget in the Market Place or anywhere else.  I hope someone can help me out on this one.  Thanks,    Jasper    

When I try to run the connectivity installer on windows I get the error   Verify File Signature "...-Connectivity-8-4.exe' is not trusted"   Some windows magic required to install? I don't see anything in the install docs.

I'm trying to encrypt the rabbitmq password as specified by https://support.ptc.com/help/thingworx_hc/thingworx_analytics_8/index.html#page/analytics/configure_property_transform_settings_linux.html#wwID0EA23O   But when I try to download the tool I get    "You are currently setup with a Basic PTC.com Account that does not provide access to this area of eSupport..."   Is there another way to get the tool? Or can I just use the clear text password instead of  "encrypt.propertytransform.password"    

Hi,   Date picker`s Changed event or textbox`s Changed Event not getting triggered when values update through service. Ex: A service returning dateTime as result and mapping with date picker`s date, whenever it returns different date, value getting updated on widget but Changed event not getting triggered. similar to text box as well.   Is Changed event applicable only for manual change?   My requirement is shift based data update, shift date time coming from a service and updating date picker.   If above case is not possible ?!! what will the solution for my requirement?   Suggestions Please...   Regards, Janakiraman P

Hi, I have used the Connect to Raspberry Pi Guide and now i have a working connectivity between TW and RPI. I have also attached a PIR motion detector sensor to the RPI.    The thing is i would like to get data real time from the Raspberry pi, right now i can only make it refreshing the Lua script once every 0.5 seconds. But in order to get movement in real time i would need something different.   this is the code i used in python. i was not able to make a loop there as i need a return statement to send it to Lua so Lua can send it to TW     #Librariesimport RPi.GPIO as GPIOimport time#GPIO Mode (BOARD / BCM)GPIO.setmode(GPIO.BOARD)#set GPIO PinsGPIO_ECHO = 8#set GPIO direction (IN / OUT)GPIO.setup(GPIO_ECHO, GPIO.IN)def distance():# set Trigger after 0.01ms to LOWtime.sleep(0.00001) StartTime = time.time()StopTime = time.time()# save StartTimewhile GPIO.input(GPIO_ECHO) == 0:StartTime = time.time()# save time of arrivalwhile GPIO.input(GPIO_ECHO) == 1:StopTime

Hi team,   suddenly Thingworx stopped running getting below error.    Failed to load FlxCore library. Ensure it's in PATH (Windows) or LD_LIBRARY_PATH(other platforms) or set with the VM arg, -Djava.library.path. Error message : com.flexnet.licensing.DllEntryPoint.entry([B)I   even we set the setenv.sh to CATALINA_OPTS="$CATALINA_OPTS -Djava.library.path=/usr/share/tomcat8.5/8.5.13/webapps/Thingworx/WEB-INF/extensions"   please get back soon.    

Hi,   I want to create classes in the JavaScript services but when I try to declare a class in the service I get the following message.   'class' is available in ES (use 'esversion:') or Mozilla JS extension (use moz)   Can someone please guide me that how I can create classes in a JavaScript service ?   Thanks  

Hi @unknown , I am try get data from thingworx with HTTP POST request (JavaScript/HTML). But i am get an error like below,   Access to XMLHttpRequest at 'http://localhost:8080/Thingworx/Things?appKey=c0f49d05-d5a2-4d73-857e-4bc6ef7f89bf' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.   I have updated "web.xml" file also enabled "Allow Request Method Switch" and "Allow Application key as URL Parameter". Still i am facing the same issue. Can i have a solution.?     Thanks.

In our application we changed the design which resulted in a new master mashup and some new mashup names.   Some users apparently have old urls stored in their favorites or use the autocomplete from the browsers URL instead of logging in via the formlogin page.   Doing so they receive an error Could not load "<oldmaster>". Reason: 404 - Entity Not Found : <oldmaster> Is there any way to redirect them to the login page or do something that makes more sense to the user (like showing a error message they understand)?   I've found a _rewrite.config in the root webapp (I suppose thingworx put it there and I just need to remove the underscore to have tomcat pick it up), so maybe I need to go down that route? I would prefer something with standard ThingWorx functionality if possible.

With a fresh install using the textual installer using all defaults.   if I run $ catalina.sh stop $ catalina.sh start   I get the error: *** CRITICAL ERROR ON STARTUP: Improper value found for model provider configuration password, system cannot start without valid password *** Web Application STATE is being set to ERROR! *** If I destroy the VM and reinstall, foundation runs fine after the install. But any attempt to restart will not start.   The config for h2 (created by the installer) contains "PersistenceProviderPackageConfigs": { "H2PersistenceProviderPackage": { "ConnectionInformation": { "password": "\u003caddsecurepassword\u003e", "username": "twadmin" } } }, (This is after finishing up the install of the analytics server, so it would really suck to have to start all over again)

Please see the attached.   Not sure why the "CustomerExists" validator keeps triggering the "EditCustomerThing" service.  This service gets triggered regardless of whether the output is true or false.  It is only supposed to trigger when the output is false.

It's been challenging, in the absence of OOTB Software Content Management (SCM) system within ThingWorx, to track, maintain code changes in different entities or to roll back in case of any entity is wrongly edited or removed.Though there's possibility to some extent to compare the differences i.e. when importing back the entities from the Source Control repository in ThingworxStorage. However this approach itself has it's own limitations.Note : This is not an official document, rather more of a trick to help workaround this challenge.I'll be using following components in this blog to help setup a workable environment.GitVSCodeThingWorx Scheduler ThingFirst two components i.e. Git & VSCode is something I preferred to use due to their ease and my familiarity. However, you are free to choose your own versioning platform and IDE to review the branches, commits, diff, etc. or simply use GIT Bash to review the branches and all related changes to the code.This blog divides into following

Hi All, I currently try to use "ImagingFunctions" from Imaging Tools Extension, but i have some problems 1) I can't input image parameter. I try these two ways but none of them work image: "/Thingworx/MediaEntities/DogJPG" /* IMAGE */image: "C:\Users\Desktop\Thingworx8\ManU.jpg" /* IMAGE */   2) What is the meaning of these parameters? Thanks!

Hello,   i am trying to get the data from my PIR motion sensor to the remote PiThing i created in the Quickstart guide. i added this code in the PiTemplate.lua   properties.PIR = { baseType="NUMBER", pushType="ALWAYS", value=0 }local sensorCmd = io.popen("python etc/custom/templates/11.py")s = sensorCmd:read("*a") properties.PIR.value = s   and i tried with 2 types (with and without a loop) of python code (the code works fine if i am trying it from terminal only in the raspberry Pi, does not work in TW) that i attached.   the other sensors as in the guide work just fine, only with this one i am not getting any data, event though the remote thing sees it as a property   can anyone please help?  

Hi,   I am using the Thingworx 8 Foundation Trial with Analytics Server. I am attempting to go through the guide "Build a Predictive Analytics Model'. Everything is working fine until I get to the point where I view the model.   The model is created successfully but then I select view Thingworx just gets stuck in a loop processing something behind the scenes. I checked the logs and there is nothing indicating there is a problem. Has anyone successfully completed this guide that could offer some tips? Screenshots attached. What I am expecting is some form of graph showing how accurate the model is.    Thanks, Martyn.
