Does the timestamp for a value change when the quality changes? This can be when the quality goes from Good to Bad as well as when it goes from Bad back to Good

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,

PLC type: Mitsubishi Fx5UEthernet Module: USR W630 (Wi-Fi to serial)The proposal PLC connects directly to Kepware through the Ethernet port and is working fine, and I want to try to connect through the Wi-Fi.My diagram is PLC - ethernet → USR W630 ))) Wi-Fi → Kepware.The purpose of the Ethernet module is to work like an Ethernet bridge. I follow this link to set up the PLC: https://industrialmonitordirect.com/blogs/knowledgebase/mitsubishi-fx5u-kepware-slmp-connection-configuration?srsltid=AfmBOop2S78y27FdOU68Ot9BDMhwFP3ieD8WG3x2a4zojZ9K_RskSMqR.In Kepware, I tried using the Mitsubishi Ethernet method to set up it, but it always shows that the reading is failing. I tried with this tutor. The problem is when I tried through Modbus TCP/IP to reading the PLC values. It looks like no problem, and I got the value of the PLC address. Does everyone have these problems, or any suggestions for my situation? Thank you first.

Hi, Out of nowhere, I started getting an error message when saving the Mashup during development. The error message is Save failed: Unable to update mashup: property name projectName not found. Thanks,

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

I’ve had this same issue with the “Notifications” entities as well. As stated in this topic (https://community.ptc.com/thingworx-developers-185/email-notification-doesn-t-work-90553). Using the “SendMessage” service on my MailThing will work, but if I set up a Notification to trigger from an event, no email is sent.  I set up a subscription to log a message on the same event and it DOES log the message.  Our ThingWorx platform is configured as a HA cluster, currently running version 10.1.1, but this issue has been across multiple versions.Performing a rolling restart of my individual server nodes seems to resolve the problem and the Notifications ARE triggered for a while, but eventually they stop working again.  I’m curious to know if more people have experienced this issue.UPDATE: Performing the rolling restart (cycling nodes while platform remains up) is NOT working in today’s instance of this problem.  I believe it worked in the past but seemingly not today.  Maybe the problem has

I have a OPC UA server (on a siemens comfort panel) that I want to read in some tags on my Kepware Server 7.1.271.0 server. I’ve set up an OPC UA channel and device, and I’m able to perform automatic tag generation tasks (I’m able to see the tags I have configured over there). The problem is that when I then try to read Kepware’s tags from this, the tag quality is bad. Maybe about once a minute I get a message in the log that the OPC UA Client driver is reconnecting due to connection loss- which sometimes, but not always corresponds to one momentary instance when the tag quality goes good and I’m able to read in the tags. The authentication is not using any security policy or message mode. I’m a bit flummoxed because I’m able to set up an Unified Automation OPC UA client that can read from the client just fine on the same machine as the Kepware server with the same settings. I did some debugging with Wireshark and saw that OPC traffic from that client to the panel was normal, while the

I am currently testing Kepware Server 7 to connect to an OPC Server via OPC DA.The OPC Server, in production, is currently has working OPC DA Client. I have configured the DCOM configuration for the Kepware Server.Set the Launch and Access Permission default and limits with the user that is also in the OPC Server as well as Access Permission. I can browse the tags but when OPC Quick Client (OQC) is connected to the Kepware, data is Bad and not updating. Here are what I observe during the testing:Data is updating:            Kepware Runtime “Use DCOM configuration” = disabled Data is not updating:      Kepware Runtime “Use DCOM configuration” = enabled Data is updating:            “My Computer” authentication level = None and “Use DCOM remote security” is enabled (connected directly to OPC Server) Data is not updating:      “My Computer” authentication level = Default/Connect and “Use DCOM remote security” is enabled. (connected directly to OPC Server)However, I tried to set the authent

Hi all,I am trying to integrate Thingworx with a Dataverse table using API calls. I am trying to update a row, but that requires a PATCH call. The content loader functions only support GET, POST, PUT, and DELETE. Has anyone found success for making a PATCH call? I have tried overriding a PUT call as PATCH but that was not supported with the Dataverse API.TWX Version 10.0.3

Hi All,While importing whole project to new server getting below error:Already checked:Thingworx version is same:9.5.1All required/dependent extension availableApplication log Error:Unable to process import org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1] Regards,Javed Akhtar

We are currently migrating our application to ThingWorx 10.1 and are looking for the following extensions compatible with this version:SCO_Common-extension TWX_Converge_Styles_ExtensionPackage LogoutWidget-Mfg-extensionCould anyone let me know where these extensions can be downloaded for ThingWorx 10.1? If they are no longer supported, is there an alternative or updated replacement available?

 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 the same issue with the touchscreen for filtered drop down. Is it resolved. My ThingWorx version  9.5.2-b494

We have a Kafka instance that utilizes Kerberos for authentication, and I want to set up an IOT Stream to push property data to it. I am successfully using Kerberos auth for a database connection from my Thingworx server (RHEL, Thingworx v10.1.1).  Do the Queue Providers support Kerberos authentication at this point?The Help Center documentation doesn’t provide much guidance on what values I should use in the Configuration of my Queue Provider.  It also seems like the only authentication available is username/password-based.  After some research I tried using “SASL_SSL” for Security Protocol and “GSSAPI” for SASL Mechanism, but I get this error: Save failed: Failed to connect to [MyQP]. Reason: Failed to create new KafkaAdminClientAny suggestions on getting the Queue Provider to utilize Kerberos authentication for connecting to my Kafka instance?Help Center reference: https://support.ptc.com/help/thingworx/platform/r10.1/en/index.html#page/ThingWorx/Help/Composer/DataStorage/Persistenc

Nonpaged Memory increase over timeI have trouble with linearly increasing “Nonpaged memory” allocation. I inspect the memory allocation with RAMMap. Our machines server system keeps getting slower and slower, so we started investigating.The picture above shows it: “Nonpaged memory” started at 776,088 KB after rebooting the HyperV. After that, it increased up by 5 GB in total.Our setup is:HyperV with Windows Server 2019; Host is Windows Server 2022.  On the HyperV: KEPServerEX 6.15 / V6.15.154.0 Omron FINS Ethernet (16 devices; CJ2 PLCs) Siemens TCP/IP Ethernet (1 device; S7-300) OPC UA Server as the connector to our SCADA system (Running on the same HyperV) In the second table, you can see that the memory allocation stops growing once I turn off Kepserver. There is one section where the memory doesnt grow even though the Omron acquisition is running. I think that in that case the time period is too short. Questions:Did you ever face a similar issue? Any ideas how to solve it? What sh

Hi. I want to use my s7 1500 as an OPC UA client over online connection. I am able to browse all OPC UA server tags, but I still can’t read the values. Note that I used OPC UA readlist instruction and the status is false for error, done or busy and the status itself shows 16#0070_0000.Please, assist me on what I might be doing wrong.

We are using 3 Kepware (KEPServerEX) servers connected to Azure IoT Operations (AIO) OPC UA Connector, which forwards data to Azure IoT Hub.Recently, we observed intermittent missing payloads/data gaps of approximately 4 minutes across all three Kepware servers simultaneously. During these periods, no telemetry was received in Azure.We raised a support case with Microsoft, and after analyzing the OPC UA Connector logs, they provided the following finding:Analysis of the OPC UA Connector logs shows that the payload gaps coincide with OPC UA BadTimeout publishing errors, i.e. periods where the OPC UA servers did not return a response to the connector's Publish requests within the operation timeout. During each of these periods no data-change or keep-alive notification is delivered, and therefore the per-minute keyframe for that period is not produced. This is the primary cause of the reported payload shortfall.We are trying to understand the issue from the Kepware/OPC UA Server side and

Is it possible to connect KepWare to a device that uses TCP socket communication? So, basically to send a command to the device (IP/port) and receive a string response?The device is Tettex 2293Command I’d like to send is ‘*IDN?’\r\nExpected response is a model and a serial number in a string.

We are having problems with two Kepware implementations reading differently.  Here are the specifics:  We have one server that has KepServerEX 6.  It reads one of our PLCs well; no problems.  We also have a new server with Kepware Server 7.  This implementation will not read from the exact same PLC.  It’s showing Bad in the OPC quick client.  Has anyone seen this before?

Hello,I have a customer with an older machine running KEPServerEX 5.0 who needs to transfer the software license to a new system.However, when attempting to use the license transfer process, an error occurs. We also noticed that the customer's Support & Maintenance expired around 2018. Even when trying to submit a support case, version 5.0 is not available as a selectable product, so we're unsure whether this is an expected limitation or a temporary issue.I have two questions:Q1. Does PTC still provide assistance for legacy products such as KEPServerEX 5.0, or is this likely just a temporary issue with the support portal?Q2. What is the recommended way to help the customer transfer the existing license? Is there still a process to transfer the license for an unsupported version? Or would the customer need to purchase Support & Maintenance again, or upgrade/purchase a new license? Any guidance or recommendations would be greatly appreciated.Thank you.

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

Despite the Runtime is still running, I don't seem to be able to use KEPServerEX Configuration to connect to that Runtime even though they are both on the same machine. By reviewing several articles, I'm convinced that there could be some hidden Config Client that is still holding on to that session, therefore I won't be able to connect to the Runtime Project. Should I restart the entire machine? or just the Runtime service? or both?

Olá, estou com problema no kepserver ex 6.5 - atualmente tenho por volta de 44 data clients, porém o sistema após alguns dias de operação começa a me retornar com mais de 1000 clients, ocasionando no travamento do servido. Podem me ajudar ?  

This error caused the kepware to restart automatically and the OPC connection to Ignition was faulted.
