Kepware

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

客戶在開啟kepserver administration的設定時會跳出，invalid or missing user information : data is corrupt跟開啟程式畫面時會當掉在cmd輸入sc config KEPServerEXLoggerV6 depend= KEPServerEXKeySvcV6再開啟錯誤訊息變成general serialization failure

We are experiencing inconsistent data loss between KEPServerEX V6.13.266 and our Atlas Copco Torque Tools. Specifically, torque results are missing in the following scenarios:Power Cycles/Battery Swaps: Results fail to report immediately after switching the tool ON or swapping batteries.Intermittent Drops: We are seeing partial data transfer (e.g., only 5 out of 9 tightening cycles recorded).Please review these cases and provide your recommendations or potential fixes to resolve these synchronization issues.Kindly setup the call to discuss or need more informationThanks,MuraliKrishnan

Hello,I have a PLC program which send the DTL from the PLC, although I can log the timestamp based on the SQL side, is there anyway to log DTL directly from PLC to Kepware with the new/upcomming updates ?

Hi, I currently use LinkMaster to map tags between my field devices and PLC. I want to get rid of LinkMaster and do the mapping in Kepware Server. I currently have Version 6 of KepServerEx. Do I need to update to V7 in order to use the advanced tag linked tags feature or is that available in the version I have now? Also, is there a way to just export my LinkMaster tags and import into Kepware or does it have to be a manual migration? Thanks 🙂

先前客戶在 ODBC 做讀寫，再透過 OPC UA 提供給 InTouch。每日固定時間會出現數值異常。我們已經更換過 Server 環境，也更換過資料庫（MSSQL / MySQL）。若直接接收溫度資料則是正常的，使用 Local Historian 也是正常的。我們嘗試過許多測試方法，目前的結論是：只要資料經過 ODBC，就會發生異常。異常現象大約持續幾分鐘，在這段時間內，A 項數值會突然升高，B 項數值也會升高（沒有太明顯的規律）。而且只會發生在特定時間。想詢問 PTC 或其他夥伴，是否有遇過類似案例，或有任何可能的原因與建議方向。Previously, the customer used ODBC for read/write operations, and the data was then provided to InTouch through OPC UA. Data abnormalities occur at a fixed time every day.We have already replaced the server environment and also changed the database (MSSQL / MySQL). When temperature data is received directly, the values are normal. Using Local Historian also works normally.We have tried many testing approaches, and the current conclusion is that the abnormality only occurs when the data passes through ODBC.The abnormal behavior lasts for a few minutes. During this time, the value of item A suddenly increases, and item B also increases (without a clear pattern).This issue only occurs at a specific time each day.We would

I use KepserverEX6.14 for linking Rockwell and siemens PLC's.We have 207 link tags in both directions. But we have troubles with 1 Siemens 1512 PLC when the communication drops (without voltage or network troubles). After the communication restores, kepserver can read the datablocks but CAN'T write to the datablock. The solution is then disable-enable tags, after this everything works like it should. My datatypes are boolean's and words (not defaults).There is a scan rate of 2000ms for PLC values. And the linked tags are written when input changes.I have tested with Auto-Demotion on and off (also with 'Discard Requests when Demoted' on/off) What can i try else?

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.

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?  

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?
