IoT & Connectivity

Can we create and modify services inside a Thing through REST API?  

Hello,   I am having a issue where the IoT Gateway, in an intermittent way, loses connection from IoT hub, then it starts a loop of errors trying to connect and being disconnected with the following messages:   Note: I hid the agent and broker link for security reason.   Date Time Level Source Event5/10/2023 1:16:13 AM Warning KEPServerEX\Runtime The MQTT agent 'My agent' published events buffer is full.

Is there a fix or mitigation action I can set in kepware? For exemple, to restart Iot Gateway automatically   Th

I am getting these two Errors while importing print extension in localserver. But same extension got imported in other servers.. Extension Exception: java.io.FileNotFoundException: C:\PROGRA~2\THINGW~1\ThingworxStorage\extensions\temp\OpenPrintButton_fb423bfc-0460-43e2-b53c-0503b46e52ae\OpenPrintButton\ui\OpenPrintButton\images\button-disabled.png (Access is denied) C:\Program Files (x86)\ThingWorxFoundation\tomcat\current\webapps\Thingworx\Common\extensions\chartWidget_ExtensionPackage\ui\lineChart\lineChart.ide.js (The system cannot find the file specified)

Hi all, I've been working with the Reference Lines feature on the Line Charts recently and while I can label them, I was wondering if it's possible to format and apply different styles to each line to help tell them apart at a glance? In my use case, the label's being used to show the value that the line is plotted at, so it'd be helpful if I could apply different colours, etc. to each line to give a little more info to them.  I can't see anything in the style properties, but not sure if there's any CSS wizardry or something I'm missing that might help? 

Hello Community. For a long time now I have noticed that when using a data table as a data source for a grid, there are some columns that show up in the grid even though you perhaps use a data shape in your service result that do not include these columns. Example: Is there any way of hiding/removing these without adding them to the data shape or having to loop over each row and removing field? Thanks,Jens

Hello, I have one device that uses the Modbus protocol. and Thingworx Kepware server connects that Modbus device and sends data to thingworx. And I have displayed device data in a mashup. In that mashup, I have added an on/off button. when I press the off button on mashup then my device will off  How can I achieve this using Thingworx, and the Thingworx Kepware server?

Hi all, How to fetch which user has access to which thing in an info table! Thank you 

Version : Thingworx 8.2.11-b1077 ( or Thingworx 9 ) I want to add Subscription when user want make property. (This subscription is essential when adding properties.) Thanks for reading.  

Hi, We are using Thingworx 9.1.14-b1128 version and I am trying to move data from data table to stream through subscription whenever shift changes will happen but service execution is not happening properly and getting error like this,moveToStream ERROR at line: 55 JavaException: com.thingworx.common.exceptions.InvalidRequestException: Not authorized for ServiceInvoke on AddStreamEntries in AAL.Production.Summary.StreamKindly guide me what kind of permission need to provide for this.        

I need to auto refresh or reload a mashup based on the change in the data. The mashup is made up of a data grid (advanced grid widget) that gets the data using a custom service that calls an REST API. Instead of calling REST API periodically to get the latest data and refresh mashup, I need to "subscribe", probably connecting thru websocket, so the mashup gets updated (advanced grid needs be refreshed) by calling service when there is new data available. Any solution for this mechanism? I have seen option of automatically updating/refreshing the grid data using the GetProperties "Automatically update values when able checkbox" in combination with ServiceInvokeCompleted event (which is based on websocket connection to property changes that mashup is subscribed to), but even then I am not sure how to update a property based on change in source data.   

Hello, I want to read data from Modbus PLC, so in the Kepwar device tag, there is a string data type. how to use that. my use case is to read the Device name from Modbus PLC and that data push to thingworx, I have connected kepware and thingworx but I want to know how string and other data type work, other than Word data tyepe

Is Monaco Editor is available in ThingWorx? Is there any Matric Document and extension file available for the Monaco? If not what are the other Editors that we can install for more user friendly to code in TWX which are supported.   Thanks.      

Hi Folks,   I have a requirement to show some loading message/gif before the mashup loads. I have tabs selection with lazy loading which takes some time to load the content (expected) once a tab is selected and want to show loading message/gif between this tab click and content load and message disappears once the Mashup load event is completed. But I don't see any event/service to trigger this message display before the mashup load. I can see SetGlobalSessionStringValue being invoked but that's an internal resources call and not part of Mashup design.   Any idea? TIA.

How many tags can be configured on a kepware instance ?How many kepware tags can I connect to Thingworx remote properties (using a single kepware instance) ?Suppose I have X tags (with X > 8000).How many things do I need to create and how many remote properties do I need to plug into each thing to have a balanced and performant system ?Thank you very much 

We want to manage several LoRA devices on Thingworx. There are gateways that read data from these devices. The goal is to manage these devices on thingworx and routing messages to their destination. We want to create thing entities for these devices and read data into its properties. How can we provision these sensors on thingworx ? Is there any tutorial that show how to connect these sensors to thingworx ?  

Hi Experts,   I have few questions to be clarified around user login.   1. How to identify concurrent user login limit ? I did check GetLicenseInfo states twx_named_user as Total Feature Count = 60. Does this mean 60 users at a time can login?   2. Is there any limit of users can access Thingworx application based on specific sizing. Example: 64GB RAM and 16 CPU sized Thingworx instance can allow how many users to login at the same time?   3. Is there any readily available tool/application to perform load testing of the Thingworx application?
