After installing Kepware Version 7.1.236  on VM Server W2025 I get this error below about UA Gateway not installedDate           Time               Level           Source                               Event11/6/2026       9:06:13.018 AM    Error           UA Gateway                           Failed to install the UA Gateway service. System requirements are not satisfied. Did I miss some pre-requisites ?Second question : once properly installed, how can we use this OPC UA Gateway?  from which tool?Best regards, 

New Timer and Scheduler things don't seem to start.The custom events never seems to fire and trigger their subscriptions.Even triggerring the scheduler thing from another thing does not seem to fire the event.

Hi All,We are facing an issue with OPC UA communication between a Zenon OPC UA Server (Version 11) and Kepware 6.18, where Kepware is configured with the OPC UA Client Driver to communicate with the Zenon system.System Architecture:OPC UA Server: Zenon Version 11 OPC UA Client: Kepware (OPC UA Client Driver) Communication: OPC UA Kepware Device Setting: Exception-Based Subscription ModeIssue Description:When communication between the Zenon system and Kepware is interrupted, the tags in Kepware transition to an Unknown quality state, as expected.However, once communication is restored, the tags briefly transition to Good quality, but the actual tag values do not update. After a few seconds, the tag quality transitions back to Bad.It appears that the OPC UA subscription is not recovering properly after the communication is re-established.Observation:We have tested the same configuration using both communication modes in Kepware:Exception-Based Subscription Mode: Communication interruptio

I am using the PTC Windchill 13.1.4.0 Rev01 guest VM on VMware. I need to access ThingWorx and would like to know the credentials to use. By default, the system redirects all calls to Navigate.Thank you.

Hello Community,I'm working on a use case where ThingWorx needs to retrieve serial genealogy/traceability information from an external MES system (Ignition MES) through REST APIs.For a given serial number, I need to access:Component serials and lot numbers Work order/production order detailsI'd like to understand the recommended approach in ThingWorx for:Consuming external REST APIs for genealogy data Modeling and storing genealogy relationshipsHas anyone implemented a similar MES-to-ThingWorx genealogy integration? Any best practices, sample architectures, or extension recommendations would be greatly appreciated.Thanks!

Hi, I have used a CWC on-prem installer to install the CWC on Thingworx.CWC installation was successful, but when I landed on the Landing Page, it is blank:​​​​​​​Thingworx Version:10.2Thanks.

Hi Team,I have installed ThingWorx Platform 10.2 and Connected Work Cell (CWC) 10.2. The CWC installation completed successfully, and all required extensions were imported successfully.However, when I open the ThingWorx Applications landing page, the header and All Applications (9-square) icon are displayed, but the landing page is completely blank. None of the expected application tiles/icons are displayed.I have verified the following:CWC installation completed successfully. CWC extensions were imported successfully. The COREUI landing page and Master Container mashups are present. PTC.FSU.COREUI.MenuConfiguration.MasterContainer_EP loads successfully. The All Applications icon is visible, but clicking it does not display any applications. I am testing with the Administrator user. Administrator is already a member of PTC.CWC.Default_UG. Browser Network requests checked during page load are returning HTTP 200. The landing page itself remains blank.When I checked the Session section in

Hi ,I'm using Atlascopco PF6000 controller .connected to Kepware using open protocol .Most of the parameters we are able to read and write .At the moment we are  facing issue with reading serial number of the product as  VIN or LTR_VIN . Barcode scanner is connected to  Atlascopco through USB  .we should  be able to read the serial number after the scanning in VIN or LTR VIN but we are not able to read  it .Could you please let me know the procedure?

I’m trying to get the information tab to show up in SCPa under the cards, tooltips and headers section under asset monitoring and can’t seem to get it to show up. What else do I need to modify to get it to show up?No matter what I do I can’t seem to get it to show up in the mashup.Thank you in advanceWe’re using 9.7 and 10.1.1 (dev vs prod)Wayne

Hi,I would like to understand best practice for the use case of developing a heartbeat function for alert duration. Let’s say an asset has an alert opened, the app should track the duration and trigger a service when the duration opened exceeds 1hour.What would be the best practice to implement this feature given it will be used for many assets?

Has anyone been able to access the Developer Portal for the purposes of making API demos?https://apim-dev-portal.ptc.com/signin?returnUrl=%2FHow can we get access with an education account?

Hi all, whats the correct procedure to update kepware server from V6.15.154.0 to V7.1.271? I’ve seen that it can be direct but also couldnt find a step by step progress. Will be great if someone have the correct steps to procedure

Dear PTC Technical Support Team,I am using PTC Kepware KEPServerEX version 6.18 and have the Advanced Tags plug-in installed.I have connected a machine through its OPC UA server and am receiving a tag with the String data type. The string contains multiple fields separated by a pipe (|) delimiter.Example input string:123|Temperature|25.6|°CThe string format is:ID|Name|Value|UnitI need to extract only the third field (25.6) and make it available as a separate tag in KEPServerEX. The source string updates continuously, so the extracted value must update automatically whenever the source tag changes.My questions are:Does KEPServerEX 6.18 support extracting a specific field from a String tag using the built-in Advanced Tags or Derived Tags functionality? If yes, please provide the exact, valid expression syntax and step-by-step configuration instructions to extract the third field between the second and third | delimiters. What should the destination tag's data type be if I need the extrac

Hello, We are using KEPServerEX 6.17.269.0 and are evaluating CA-based trust for OPC UA client application certificates.We successfully tested importing a CA certificate into Trusted Clients and connecting an OPC UA client whose certificate was signed by that CA, without individually approving the client certificate.We also found a similar discussion describing the same behavior:https://community.ptc.com/kepware-396/requirement-trust-certificate-from-few-clients-automatically-157567However, we could not find any official documentation confirming this functionality.Could someone from PTC confirm: Is CA-based trust for OPC UA client application certificates officially supported in KEPServerEX 6.17.269.0? Does trusting a CA certificate automatically establish trust for all valid client certificates issued by that CA? Is this behavior officially supported and expected to remain available in future versions? Are there any specific requirements or limitations regarding certificate chai

This is a Mess.   We have been paying for Support each year. Now today when I actually need support they say I don’t have a support contract.  I have the guy from sales showing a screen shot of the system showing my Invoice for support and paid in full.  Simply reboot the VM today and it broke the bindings. Can’t get the issue fixed due to support not willing to talk to me saying I don’t have support.   Anyone ever go through this?  How do I get this fixed.  Production is down and I can’t even get a call back from ptc. 

Hi, Before upgrading to 10.2 the MCP server was reachable by default at https://mydomain.com/Thingworx/mcpnow after upgrading to 10.2 it returns HTTP status 400 - Bad Request.Is there anything needed to be done during configuration/installation for 10.2 that could have been missed? Thank you.

Hello.We are planning to trust an updated Ignition OPC-UA client certificate using the OPC UA Configuration Manager in KEPServerEX.We have put together the following procedure based on the official manual (OPC UA Configuration Manager Help v1.044), but have two questions we would like to confirm.Planned Procedure:Open the “Trusted Clients” tab and confirm that the new Ignition client certificate (Ignition OPC-UA Client) is listed. Verify that the SHA-1 Fingerprint of the listed certificate matches the updated value recorded on the Ignition side. Select the new client certificate, click “Trust”, then click “Close”. Right-click the KEPServerEX icon and select “Reinitialize”. Do not delete the old client certificate until the entire work is complete.Questions:① After clicking “Trust” on the updated certificate, is it necessary to perform a Reinitialize?The official manual shows a note at the bottom of the Trusted Clients screen stating “Server Runtime reinitialization is required to utili

Hi all,We are supporting a site where Kepware Server 6.15 (drivers V6.15.132.0, Modbus TCP) sends data to ThingWorx 10.2 over the Native Interface. We need some help with the points below.What is happening- The customer says Kepware closes by itself about every 3-4 days. Whoever sees it first opens the application again.- While it is closed, no data from any device reaches ThingWorx. Store and Forward does not help here, as it runs inside Kepware.- The longest case in the Event Log was on 10 Oct: runtime exit at 3:00:22 AM and next start at 9:04:15 AM (about 6 hours).- In the log we see 7 runtime exits. Six of them restarted within 1 to 3.5 minutes.What the Event Log shows- Each exit is preceded by "Administrator configuration session ended".- Then: "Runtime performing exit processing."- On the day of the 6-hour gap, the reopen attempt logged: "Account '<account>' does not have permission to run this application." and then "Timeout waiting for server runtime to start."- The custo

Does anyone know whether this case was solved and closed?

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.

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?

Hi,I want to upgrade Kepware from V7.0.236.0 to V7.1.271.0.Wanted to ask is there a need to uninstall the V7.0.236.0 version or we just need to install the V7.1.271.0 through the .exe file and it will get auto upgraded?Kindly help.

I have multiple alarm tags in PLC.  I need to set an integer (long) value based on those tags such as If tag1 = true then 1000 or if tag2 = true then 1005 or if tag3 = true then 1010 I can’t seem to figure out a formula that will let me do something like that.

We are using Kepware server as OPC UA server as well as OPC UA client in two different machines. When I try to connect Server at Client, Server's certificate is automatically getting fetched in Client's 'Trusted servers' tab of OPC UA Configuration manager, which I am trusting manually. Similarly, when I again try to connect Server at Client, Client's certificate is getting fetched in Server's 'Trusted Clients' tab of OPC UA Configuration manager , which I am trusting manually. However, again when I am trying to connect still I am getting 'Client or server certificate invalid . Configure or verify the certificates' log in Server and not able to connect.  With Security policy set as NONE the communication is working, hence there is no TCP port connectivity issue, but when Security Policy: Basic256Sha256, the communication failing. I tried reissuing certificates using OPC UA Configuration manager and manually exporting and importing certificates from Server and Client but same issue is c
