Hi, I need to connect to KepserverEX 5.8 in a Windows 2000 Pro/Sp4 workstation with Ewon Flexy 205.The goal is using the ewon (in this case 5 of them) as middle point to communicate s7-300 PLC with Wonderware 8.0 using KepserverEX 5.8 as the OPC server. When configurating KepserverEX 5.8 channel i use OPC UA and configure UA server in the channel (see attachment 1) and when i try to import items on  the device to import the tags of the Ewons an error appear (see attachement 2).See attachement 3 for ewon configuration.Any suggestion to address this?

Hello, im setting up tags in Kepware where previously we have used RS linx, the booleans tags are all showing 0 when it should be a 1 and are not changing at all. The quality of the tag is good and its showing correctly (1) in RS linx but a 0 in kepware, anyone got any advice? Kepware server 7

I am trying to get a hold of Sales in order to purchase additional license options on my Kepware OPC Server package.  I have tried submitting a ticket but I received a "you are blocked" response to that.  I've tried calling but after being on hold for nearly an hour, it just disconnects me.  I mean, really?  I'm wanting to buy stuff from you.  Does PTC really make it that difficult to make a purchase?  Can someone PLEASE contact me? m.barnes@amrize.com

使用者希望使用有效期限為10 年或更長的自簽名憑證。使用原有的KEPServerEX客戶端時，只需一個憑證即可實現雙向通訊。然而，由於架構較為複雜，目前似乎無法在多個系統間重複使用自簽名憑證。請確認自簽名客戶端憑證是否可以被多個伺服器使用。OPC UA證書會自動續約或延長有效期限嗎？如果用戶端憑證過期，是否會影響現有系統？例如，是否會導致EAP無法連線等問題？ The user would like to use a self-signed certificate with a validity period of 10 years or longer. With the original KEPServerEX client, only one certificate is needed for mutual communication.However, it seems that a self-signed certificate cannot currently be reused across multiple systems, possibly due to the more complex architecture. Please confirm whether a self-signed client certificate can be used by multiple servers.Will **OPC UA certificates automatically renew or extend their validity period?If the client certificate expires, will it affect the existing system? For example, could it cause issues such as EAP being unable to connect? 

Hi! Has anyone used the KepServer Siemens Suite with Siemens new S7-1200 (G2) CPU's? Best regardsPär

各位先進夥伴好，近期接到一個CASE，客戶突然想做升級，4版到7版(當前最新)。Dear partners, recently we encountered a case where a customer suddenly wants to upgrade from Version 4 to Version 7 (the current latest version).因為4版真的太過古老，最簡單的OPF匯出，都不知道能否順利？想討論有甚麼注意事項。Since Version 4 is extremely old, we are not even sure whether basic functions such as OPF export can be completed smoothly. We would like to discuss what considerations or precautions we should pay attention to.軟體、系統、硬體都可以。Any suggestions related to software, operating systems, or hardware are welcome.

Dear community,   I would like to color the entries of a Dropdown, like this: The Color would come with the InfoTable for the data feed. Anyone an idea how to do this?   Thanks Benny

Hi everyone, I’m facing a performance issue related to PDF rendering between two widgets in ThingWorx. We are using a Repository Connector (not a local FileRepository) where all PDF files are stored.Each PDF is around 4 MB in size.   When I render a PDF through a WebFrame widget, it loads almost instantly (within a second).However, when I render the same PDF using a ThingView widget, it behaves differently:   The first PDF usually loads quickly. But when I open subsequent PDFs, the loading time increases significantly (sometimes up to 8 seconds or more). It feels like ThingView is reloading or re-parsing the file differently each time.   Additional Note:I have also tested the same setup using a local FileRepository, and the ThingView widget works perfectly fine there. The performance issue seems to appear only when using the remote Repository Connector.What’s confusing is that the WebFrame widget still loads the same remote PDFs much faster, so I’m trying to unders

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

We have a successful connection from KEPServer to a Siemens PLC using Siemens TCP/IP Ethernet. The only issue we are having is that when the PLC is powered off, we are filling up the KEPServer event log with hundreds of entries per hour. . Is there any way for KEPServer to deactivate the tags while the PLC if offline, and re-activate when the PLC is powered back up?  

Hi all,We're running Thingworx 10 as SaaS with Thingworx Kepware server 6.18 on-prem. I sometimes notice that devices that are disconnected in kepware (e.g. powered off), still have properties in Thingworx that show good quality. When I run GetPropertyDiagnostics on any of the properties, the results shows CurrentQuality as BAD.It also seems like the behavior is not always the same, most often the disconnection will change the property quality & values as expected.As Push Type we use 'Pushed based on deadband', when I change this to 'always', the property quality changes and values are set back to 0 (so the expected behavior) but with ten thousands of properties the impact on our environment will be too high.Is there any other way to ensure that a disconnected machine is always seen in thingworx without using a workaround like a lifebit?

Is it possible to access other Channels' Tag data from within a Universal Device Driver profile? I need to save some Tag data to a csv or text file and am looking at the possibility of using UDD in File Mode to periodically write the data values from a channel (Modbus TCP for example) to file.  I'm just not yet sure if there's a way to access 'outside' Tag data from within the UDD Channel/profile. 

We need to pull data out of an old 5/250 but Kepware is preventing us from entering the address as they need to be.  the PLC5 architecture is "N7:40" for example but in the PLC5/250 it requires a leading digit to identify which module the address is in so "N7:40" in a 5/250 would be "0N7:40".  Has anyone had any experience with this? THank you,Dean

Hello, We are currently running Ignition（SCADA soft） on Linux and would like to use KEPServerEX as the OPC server/gateway. However, the documentation indicates that KEPServerEX is Windows-only, and using Windows is not an option in our environment.We also considered other options such as KEPServerEX Edge, but the available drivers/licensing do not match the PLC we need to connect to, so Edge does not meet our requirements either.Questions / what we are trying to achieve:Are there any plans for KEPServerEX to support Linux (either natively or officially via containerization/other supported deployment methods)?Our goal is to acquire data from a PLC using KEPServerEX and then provide that data to Ignition (e.g., via OPC UA). What is the recommended approach when Ignition is running on Linux and Windows cannot be used?Any guidance would be greatly appreciated. Thank you.

KEPServerEXVer6.17Local Historian (501-10,000 tags)OPC Connectivity SuiteWhen analyzing the historical data from LocalHistorian-HDA,we found that data updates were stopped for approximately 12 minutes around 00:58:17 on November 13, 2025.No quality abnormalities (e.g., Bad) were found on the OPC DA side before or after the stopped period.Is there anything we can learn from the Application Report that will help us identify the cause of the 12-minute stoppage in HDA data updates?

Hello Everyone,We are using the Advanced Tree widget in our mashup. The same widget works fine in the QA environment but fails in the PROD environment. Could this be related to data loading?In PROD, both the search functionality and the parent-child relationship are failing. Both environments are running on ThingWorx 9.1. Thank you

Hi everyone, I have two ThingWorx projects that depend on each other. Both i want to  import as packages into our server. I noticed the following behavior: When I reference the Thing dynamically like this, it works without any issue means package is created:   const Controller = "thingName; Things[Controller ].serviceOne({ id: 234, state: "complete", });   However, when I try to use the dependency more directly (e.g., referencing it statically without the intermediate variable), I get an error while packaging for dependency.   Things[thingName].serviceOne({ id: 234, state: "complete", });   My questions: Is there a recommended way to handle cross-project Thing references? Any insights or best practices would be appreciated. Thanks in advance!
