IoT & Connectivity

I have upgraded our Kepware system and I need to remove LinkMaster and the OPC server that is with it.  Since everything seems to break Kepware licenses, are there precautions that need to be taken in uninstalling LinkMaster or can you just use the Windows Uninstaller?

Hi,I have installed the IQNOX Thingworx Map widget from the website and I have Imported it to the Thingworx: But the Map is not showing up in the Widgtes:  There is no widgets of google showing up:   Thanks.

The ThingWorx mashup-vendor-shared.js file is using the jQuery scrollintoview plugin v1.8 (2011), which is vulnerable. We would like to upgrade this to the latest version, but since it is bundled within ThingWorx, please advise on the recommended approach for upgrading or replacing this plugin.Current environment:jQuery: 3.7.2 jQuery UI: 1.14 jQuery Migrate: 3.5.2

I am using ThingWorx Platform Release 9.1 and DatecodeSP1 Users or Developers are not able to see the mashup Runtime, even though they are in the "Administrators" group. Sometimes, after restarting the laptop or incognito Runtime shows up, but most of the time, the dashboards won't come up. We tried in different ways:1. Different Browsers2. Restarted Laptops3. Incognito Windows4. Restarted the Thingworx with clearing cache When the Runtime Dashboard is opened, we get HTTP Status 403 – Forbidden Here are the errors that I faced HTTP Status 403 – Forbidden

We have successfully migrated the existing PostgreSQL 15.3 database to a new PostgreSQL 15.3 server and established connectivity with the newly installed ThingWorx 9.4.0 environment on the new servers.As the next step, we need to upgrade ThingWorx from version 9.4.0 to 10.0.Could you please advise on the recommended approach and best practices for performing this upgrade?For your information, ThingWorx and PostgreSQL are hosted on separate servers.

Hello, Has any configured KEPServerEX to be able to run timers between a start and end trigger tags? I want to be able to setup Operation Cycle Time Logging from plcs tags and be able to calculate the time that it takes for the operation. Example: Timer between hit of a start button and final test saying that the test passed without having to create a timer in the plc itself to monitor this operation Thank you

As per the original post.   Hi,   I have the similar problem as NM_12850686. Could you please share the port issue solution?   Here is my setup: Cleco Controller mPro200 - Open Protocol - Port 9002 - Activated Cleco Controller mPro200 - TorqueNet- Port 12345 - Activated Cleco Controller mPro200 id : 192.168.50.20 KepServerEx - Channel:TorqueToolEthernet - Device:Cleco (Open Protocol - 192.168.50.20 - Port: 9002)   Both the controller and the port can be ping successfully from the PC.   However, none of the tags receives information from Cleco. Could you please look into this?   Thank you,LP

Hi, I have a customer that is using Kepware Server for OPC DA / OPC UA / OPC DA communication between two systems. At the moment we are having issues with certain slow updating tags (booleans and integers) that freezes and are not updated between the two systems. Continuous updating values are no issue... The issue seem to be that the tags gets timed out and are not correctly mirrored between the systems. If we create local subscriptions on the KepServer node on the actual tags the error seem to disappear. Is there a way to configure kepware to establish the subscription to the source tags regardless of the client status? We cant find any correlating error messages in kepware. 

Hi there, I’m trying to set up a connection between Modbus TCP driver in Kepware Server 7 and modbus ModRSsim2 simulator.Port 502 and device ID = 1 are used in both ends.When Kepware starts, it shows the following line i log window:   Channel1 | Starting unsolicited communication. | Protocol = 'TCP', Port = 502.   Should it be something like Modbus TCP Client/Master mode instead ?In Kepware Server 7 where do you switch between Modbus TCP Client/Master mode and Modbus TCP Server/Slave/Unsolicited mode when you set up a channel ?Any guidance would be greatly appreciated.Thanks in advance,Henrik 

We have a connection issue between KepserverEx 6.18 and Janitza UMG96-S2 power measuring device. The connection is working and the tags can be readed via QuickClient but during the reading the quality of some tags randomly switching from good to bad for a while. The strange is that not all of the tags quality switches and it happens randomly. Does anyone has a similar issue with a Modbus TCP connection?

Hi,We are facing with issue that we are not sending the data thru MQTT.On Kepware side there was no message that we are disconnected from MQTT.After several restarts of the Kepware IoT service, the problem was solved, but it reappeared after some time.We have openlogic-openjdk-jre-8u482-b08-windows-x32 JRE version installed on Kepware server. Thanks in advance.

hi all,I’m trying to setup a Modbus TCP/IP connection on a thingworx Kepware server 6.18, to an energy meter from Circutor (CVM-E3-MINI-ITF-WiEth, manual can be found here M170F01-03.pdf). I’ve setup connections to other energy meters before using Modbus TCP/IP without issues, but with this device I keep getting unrealistic values.I’ve literally tried using all different combinations on Data access & encoding, but the output I’m seeing seems either extremely high or extremely low, sometimes more or less stable but often also varying a lot which can normal if the byte order was swapped.The manual doesn’t really tell much on the Modbus-TCP setup, like what device-id I need to be using. So far I’ve tested mostly with device-ID 1 which seems most logical in that case, but I’ve used other device-id’s like 2 or 7.I’m hoping anyone has some experience with these types of devices or recognizes this type of behaviour and has some ideas on how to solve it.Many thanks in advance.H.

 This has become a high-priority concern for the business because it limits flexibility in volatile resource and production planning situations. This continues to be a significant challenge for Xylem specific sites, where production planning is driven by daily resource availability and custom/special order demand. Mostly the planning is been done on the basis of the information for the particular day only. However this limitation is impacting negatively in a way as it shows up in dashboard inaccuracies and is limiting Xylem site’s ability to operate effectively within DPM.Very High Impact - As we are not able to use the application for what we expected it to perform and top of it this limitation of advance scheduling is impacting negatively from site performance (OEE) perspective.

I have a few analysis models enabled and running. Up until recently the Analysis jobs were getting executed perfectly at an ideal rate, but recently the issue is persistent. The issue is the jobs are getting submitted in the analysis jobs but the time taken before the execution begins, is roughly around 2 minutes. As a result the queueing is increased with the state of each job as "WAITING". This delayed execution is not ideal for our instance, as we are logging data for every 30 seconds , as the execution is delayed the real time updating of the prediction values is also affected. Is there any way to start the analysis execution as soon as the analysis job is submitted? What might be the reason for the delay in the beginning of the job execution? I have attached the photos of the issues we are facing below.   The Version we are using is:Analytics  Version=  9.5.0-r4Thing Worx Software version = 9.5.0-b143 

Hi,I’m using ThingWorx 9.3.0-b20 with Analytics Manager, and I’m facing an issue where analytics jobs stay in “Waiting” state for a long time.This does not happen all the time, but occurs around 3–5 times per day.The jobs only start running after I manually trigger another job (e.g., test an analysis model or create a new job). Once I do that, the waiting jobs immediately execute.Expected: Jobs should start automatically without manual trigger.Actual: Jobs get stuck until another job “wakes them up”.Questions:Is this a known issue in 9.3? Any configuration related to scheduler/queue causing this? Any workaround or fix?Thanks in advance.

Hi,I am using Kepware Server v7.0.236 with FTView v16 on Windows Server 2025 in a Domain setup.  The Kepware Server is installed on the same server as the FTView application.  I have a FTView Client PC (Windows 11 24H2) which runs the FTView client.  The problem is when I run the FTView client on the W11 PC any tags on a graphic which directly address the Kepware server don’t read. I’ve gone through every step of the Kepware “Configuration Guide Remote OPC DA (DCOM)” and had a 2 hour Teams session with Kepware UK Tech support (MAC Solutions) while I’ve had remote desktop connection to the server. We went through the settings on both the Server and Client step by step and confirmed the recommended settings were in place and even uninstalled/reinstalled Kepware but nothing has worked.Anyone had similar issues and found solutions ?

I Transferred a Perpetual License,License shows as ‘good’ in the license utility.License shows as ‘Active’ on the Kepware website.BUT KepserverEX is still showing a 2hr time limit, after which, it deactivates. License support expiry is 10/2019.I am uncertain what Kepserver version it was originally running on.Now running on Kepserver 6.18.318.0 QUESTIONS:Is this a Kepserver version issue? How do I see what version of kepserver my licenses need?Or has Kepware made it so you can't transfer older licenses without paying?

Hello PTC Community,I would like to confirm the expected behavior of the Kepware _System._NoError tag when it is referenced from ThingWorx.I reviewed the following support article:CS466164NoError tag value fails to update in ThingWorx when NoError tag is updating in Kepware Modified: 19-Mar-2026 / Last Seen: 15-Apr-2026As I understand the article summary, it states that:the NoError tag is updating in Kepware, but the NoError value in ThingWorx is not updating, the cause is that only the NoError tag is bound, and the suggested resolution is to bind a device static tag on the same Thing together with _System._NoError, ensure that the static tag completes its first scan, and then verify that the NoError value updates in ThingWorx.However, from my understanding, _NoError is a system tag representing the device communication state on the Kepware side, while ThingWorx is in the client position relative to Kepware.Because of that, the explanation that _NoError is not evaluated until a normal

What device-model correlates to the F3SP53-4s CPU yokogawa controller driver?  I cant seem to correlate the options (UP27 UP150 UP350 UP550 UP750 UT37 UT38 UT130 UT150 UT150L UT152 UT155 UT320 UT350 UT350L UT351 UT420 UT450 UT520 UT550 UT750 US1000) with the model. Are there options I’m missing?  Am I using the right channel driver? 

I am using ThingWorx Platform Release 9.4 and DatecodeSP1 During installer inplace upgrade of thingwrox in windows with postgress as persistent provider. Do we need to stop the service of the existing TWX running ? I didn't find the specifics regarding this.

How can the LLM Accelerator be integrated with the native MCP capabilities introduced in ThingWorx 10.1 to enable interoperability with Mistral AI models? Additionally, are there any sample implementations or reference code available for building a chatbot within ThingWorx 10.1 and generating reports natively using these AI capabilities?

Mashup Expression and Validator functions are not reliably storing changes to code as of Friday 5/29I open the function, make some change to the code within, click Done button to close the function editor, and when I reopen the editor whatever change I made has disappeared, reverting back to the previous value. This includes a brand new function created to test this bug. A new expression or validator created with Output = "test"will be simply a blank window after closing and reopening.I first discovered this on Friday 5/29 and again today and have tested and found the same bug in both Firefox and Chrome with the latest versions of both. Clearing browser cache and restarting had no effect. Closing all active edits in Thingworx composer and returning had no effect.This also occurs in a new, blank mashup as well as existing complex mashups. 

Hi,  I was working on a Dashboard, I see a new Property (ConfigurationMashup) in the Mashup, in Thingworx 10.0.  What does it do actually ? Thanks.
