ThingWorx 10.1.0-b47, SDK Utility build matching 10.1.A custom Gen-2 (Lit-based) Web Component widget, built with the official ThingWorx Web Component SDK Utility (mub).imports and renders correctly in Mashup Builder, but its Style Properties panel shows zero rows.The StyleTheme picker is visible, but nothing underneath, not even a flat list, just empty.We're able to fall back to classic STYLEDEFINITION-based styling, but our goal is the style dictionary tree.Is there a required steps beyond a normal mub build + import for a Gen-2 widget's style dictionary to show up in Style Properties?

Does someone know how to use the“new JSON-based source control format, currently available as a preview capability in 10.2”feature? I can’t find anything in docs or by trying export via Composer I only get .xml files as before. I activated beta features in PlatformSubsystem, but also no luck with it.

Industrial environments have never been short of data. The challenge has always been connecting that data, understanding its context, and making it available to the applications that need it.A machine might publish a temperature value. A production system might know which line that machine belongs to. An MES might know which production order is running. An analytics application might want to consume all of this information.The data exists—but historically, connecting these systems often meant building integrations around individual systems, properties, and point-to-point connections. That model becomes increasingly difficult as industrial environments grow more connected.With ThingWorx 10.2.1, the MQTT extension is taking an important step forward with MQTT v5, bringing modern MQTT capabilities, stronger security, improved responsiveness, and—perhaps most importantly for modern industrial architectures—greater awareness of the context carried by MQTT topics.This is where MQTT v5 and Un

From debugging and source control to automation, testing, and AI-assisted development, a look at how the ThingWorx developer experience is evolving.Modern application development is no longer just about writing code. Developers expect integrated source control, repeatable workflows, automated testing, CI/CD pipelines, and increasingly, AI-assisted development. These capabilities have become standard across the broader software development ecosystem because they help teams move faster, improve software quality, and scale engineering practices.ThingWorx application developers face many of the same challenges. As applications become larger and more collaborative, developers need better ways to troubleshoot issues, manage changes, automate repetitive tasks, validate functionality, and leverage emerging AI technologies without sacrificing reliability.To address these challenges, recent investments in ThingWorx developer tooling have focused on making the platform more compatible with modern

When accessing the server, which does not have network access, I open Kepware > Licence Utility. There, I can see my license with a Support End Date of 05/2024.I received a .lic file from our partners, which is supposed to be the renewal license, and the file is already available on the server.Back in Kepware > Licence Utility, I click Renew > Import File and select my .lic file. After confirming, however, nothing happens.Can anyone help me with this?

I created an account but it will not let me download any software

I have a mashup that contains a ptcstextfield widget.  NumericInputMode is selected.  Allow decimals is selected.  DecimalPlaces is set  to 2.  When I attempt to enter a decimal value, it transposes the numbers.  If I enter .75, it shows the value as .57.  Any ideas on what might be causing this issue.

I am using ThingWorx Platform Release 8.5 and DatecodeSP2 Our customer is currently using ThingWorx 8.5.2-b90, which is an older platform version. We plan to propose a migration to a currently supported or latest ThingWorx version to improve platform supportability, security, performance, and future compatibility. The current environment consists of: - Current Version: ThingWorx 8.5.2-b90 - Number of Projects: 41 projects - Custom CSS: Custom CSS is implemented across all 41 projects - Existing Customizations: Custom services, widgets, UI configurations, and other project-specific customizations may be present - Migration Objective: Migrate the existing applications and configurations to the target supported/latest ThingWorx version while minimizing impact to business operations. PS. twx_mashup_builder = 1434 twx_things = 881

I need to purchase a Kepware Allen-Bradley ControlLogix Ethernet OPC Server license.It appears that Kepware / Velotic no longer offers an online purchasing option, and I have not been able to locate a direct phone number for sales.Does anyone have current contact information for Kepware sales or an authorized distributor who can assist with purchasing the license?

Hey everyone,we know already that changing ThingTemplate for an existing BaseThingTemplate is not possible through composer and there exists some topics that suggest to modify the XML file in order to be able to change this. However this only works on “unsealed” extension and not for already sealed ones (isExtension=true, isEditableExtensionObject=false)We know came across changing the baseThingTemplate Type in the Database directly. e.g. through the following query:  UPDATE thingworx.thingtemplate_model SET "baseThingTemplate" = 'RemoteThingWithFileTransfer' WHERE "name" = 'BaseThingTemplate';We definitely know this is not the supported way to go but we also didn’t find any other solution which makes a change possible other then having to recreate all 20k+ devices again which means a lot of migration effort.Therefor I wanted to ask if you see any downside or potential risk here performing this. Obviously this change takes only affect after rebooting Thingwor

The project configuration seems really limited. Only allowing one person at a time to connect and make changes.We were hoping the API would help but it seems to require giving itself write access over and over again for every edit you make, changing the project ID and not allowing, as far as I can tell, any kind of bulk import. So if I want to manipulate 100 tags it gives itself write access 100 different times and is fairly slow.I'm not sure but it seemed like anytime the API was manipulated anything if there was another user live looking at the project they lost access.Am I missing something? Is there a way to have more than one user editing a project at a time? Is there any way to bulk import devices and channels and tags in one shot with the API?

HelloI am not able to register any tools using AddTools in the MCP resource.It won’t accept the inputs I makeIs there ANY documentation on this or help more than the very limited information in Help pages?I want to expose a service that takes a string input and gives a JSON response for instance

Dear All, I am trying to communicate FX5 with Kepserver, however failing to connect despite different trials. I have set PLC setting to SLMP setting with both TCP and UDP port and set it accordingly on the Kepserver. Still not able to communicate with the PLC with Tags value as BAD.I am attaching the pictures for reference also.  

Hi, Recently, I have been facing an issue with the timer, which is very critical for us. Error Executing Event Handler 'InvokeCodeVentHandler' for event Type.Thing:Test.Timer:Event.TimerI have gone through below Articles, but nothing helped:Article - CS403375 - In ThingWorx Platform Error message: Error Executing Event Handler 'xxx' for event Type.Thing:Entity.xxx:Event.xxx is seen often in the Application LogArticle - CS333561 - Error Executing Event Handler '<Event' for event Type.Thing:Entity:<Thing>:Event.ScheduledEvent is frequently logged in the ErrorLog of ThingWorx PlatformHas anyone had this issue? And has any Root cause been found? Thanks,

Hi everyone,I am looking for some advice or assistance regarding a sudden licensing failure. We purchased a perpetual license for KEPServerEX 6.6 in 2018 through a reseller, INRAY (bundled with their FAS Server software).The system had been running smoothly without any issues until August 1, 2026, when the following error suddenly began appearing in the event log: Licensing - License for feature Siemens TCP/IP Ethernet cannot be accessed [error=-157] and must be reactivated.In the License Utility, the status for the Manufacturing Suite product is currently showing as Status - Broken: Anchor. (Note: We have not made any hardware changes, MAC address modifications, or VM migrations recently).Our reseller, INRAY, has declined to assist us because we do not have an active support contract with them. However, we are not looking for software updates or engineering support—we just need to restore a paid perpetual license that broke unexpectedly on its own.Has anyone encountered this specific

I am using ThingWorx Platform Release 9.2 and DatecodeSP11 We are currently using ThingWorx 9.2.11 with ThingWorx Navigate 9.2. We are using the ThingView widget to load and display 3D models within a ThingWorx Mashup. The 3D model we are loading contains the main product/model along with its packaging, where the packaging is included as a subpart/component of the same 3D model. We would like to know whether there is a supported way to hide or make the packaging component invisible in the ThingView widget, while keeping the rest of the 3D model visible.

I am using ThingWorx Platform Release 9.2 and DatecodeSP11 We are currently using ThingWorx 9.2.11 with Windchill Navigate. We are using the OOTB Windchill Navigate services to retrieve and populate a 3D model in the ThingView widget within a ThingWorx Mashup. Our requirement is to hide or disable specific parts/components of the loaded 3D model. We do not want to hide the complete model. Instead, we need to selectively control the visibility of individual parts or components within the 3D model displayed in ThingView. Could you please confirm whether ThingView supports this functionality in ThingWorx 9.2.11? and is there any workaround

Hi everyone,I have a scenario where a very large SQL query processes data from multiple large tables and applies different joins, filters, and calculations before producing the final output. The execution time can sometimes reach 40+ seconds.One important detail is that this process is not a frequent operation. It only occurs about 3 times per month, so optimizing for high-volume traffic is not a requirement.Because of this, I'm questioning whether implementing a full asynchronous processing architecture is worth the added complexity. At the same time, simply increasing server timeouts doesn't feel like the best practice.For a low-frequency but resource-intensive operation like this, what would you recommend?  What approach have you used for similar low-frequency, long-running database operations?I'd appreciate any recommendations or real-world experiences.Thanks in advance! 

Hey, Is there a way to get the Logs from ThingWorx to my PC so my Python or AI can analyse them?Thanks,

I have KepServer on PC IP 172.17.90.31 with Modbus TCP/IP Driver for Yokogawa DCS using ALE111 device with IP 172.17.90.30 communication. It seems comms is only established when Device ID in the project is <127.0.0.1>,0 and not with <172.17.90.30>,0. I understand this is due to ALE111 is Modbus Master in this case. I am facing issues where TAGs value are not accurately updating in some TAGs, but some are ok. I also have issue where the real parameter values in data type "float" always show "0" and do not update on live run. If I stop the KepServer service via Windows "runtime - End Task" and then restart KepSever project, the QC on initial handshake will display the last stopped value or stored value on the parameter TAGs, but on second update onwards, it will go back to "0" value and no update. I can successfully write to these parameter TAGs via QC and confirm the handshake with device. Can I please get support, if the Project configuration needs modification or Device pr

I’m having similar issue. I restarted the service multiple times. Each time I restart the Runtime service, the problem seems to go away but then the KEPServerEX Configuration tool stops working again. What else could be done to permanently fix the issue?

I HAD A PROBLEM WITH A VM AND I HAD TO RECOVER IT, IN THE PROCESS I LOST THE LICENSE, I HAD A PERPETUAL LICENSE BUT I NEED TO REACTIVATE AND WHEN I TRY IT  HOW TO SOLVE IT?

I configured Kepserver V7 to get data from Siemens S7-1200 using TCP/IP ethernet. I followed all the steps shown on this guide. https://support.ptc.com/help/kepware/drivers/en/#page/kepware/drivers/SIEMENSTCPIPETHERNET/HelpContents.html#However, I kept having error saying “Data block - ‘DB131’, block start = 0, block size =32, Reason = ‘Device returned protocol error’. Error class = 0x81, Error Code = 0x4.” I researched this error and I learned I needed to install TIA Portal Exporter installed to change .ap file to .tpe file. Then import the .tpe file to kepserver device. This resulted error saying “Error initializing the Openness API. Please verify all necessary components are installed”. I reinstalled TIA portal to verify openness is installed and it was installed. Please advise how I can resolve these issues.
