Kepware

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?

Im having issues trying to communicate KepServerex V5 5.13 with BACnet server Automated Logic WebCTRL. The server have some HVAC, eletrical and Diesel equipments, but some of these devices are listed on ARCnet network. They dont have IP Address, or MAC Address that i can read, they have their Network Number, 1 MAC Address digit and their Device instance.I managed to connect some devices to Arcnet, but these devices are listed under Routers that are configured as BBMD Devices, and the other devices listed in other ARCnet networks, i can't link or manage their communication in KepServer BACnet/IP driver. Configuration for ARCnet devices that are communicating:Kepserver device ID: <network number listed in WebCTRL device> . <device instance listed in WebCTRL>.Kepserver discovery scope: Using Who-Is/I-Am - Remote Scope.Kepserver COV: Do not use COV. Error messages:- Error reading tag '<tag_address>' on device '<device_path>' (Class: 1 (Object), Code:

I can connect to my Engel IMM via UA Expert, but I am unable to find the information to make the same connection via Kepware Server.  Where can I find the information or can someone provide me the information.

I've to do a migration from KEPServerEX 5.8 to KEPServerEX 7, step by step, using a BRIDGE KEPServerEX 7 solution, that initially it is connected in OPC-UA to all OLD channel/device/tags of KEPServerEX 5.8.Then in a new Server with KEPServerEX 7 we migrate step by step each original channel, then connecting the BRIDGE to the new one migrated.Finally we will have the BRIDGE only linked in UA Client to the new KEPServerEX 7 migrated, and no more to the old one KEPServerEX 5.8. Now we are testing this migration scenario creating in Kepware 7 BRIDGE an OPC-UA Channel to Kepware 5.8 OLD, but we have some issue when the remote Channel in Kepware 5.8 is it self an OPC-UA driver.In some cases, the tags seems to be unknown and in bad quality, why ?The issue happen also if I try to read the remote TAGs via UAExpert tool To understand/replicate the issue I have done also another example locally, in order to exclude network and OPC-UA configuration, both in

Using the Open Torque Tool Protocol driver, I am struggling connecting a Atlas Copco MT Focus 6000 (not Power Focus). According to the Kepware driver supported devices, this is a supported device. However, it has proven impossible to connect to the LTR tags and the 1201/1202 tags to get torque results. We have validated that the 'Communication' messages are successful and valid, and can validate data via diagnostics. However, the driver does not recognize the data format and sets most tag quality to 'Bad (Out of Service)' We have tried every message revision and MID8 / MID60.  Is it truly possible to get torque result data from an MTF6000 using Kepware's Open Torque Tool Protocol driver?

We are currently experiencing a performance issue with our OPC UA communication. We have an application developed in FactoryTalk View SE version 15, which displays several graphical screens that rely on data coming from Kepware 6 through an OPC UA connection.The problem is that the graphical elements take a long time to receive updated information from Kepware. The data refresh rate is significantly slower than expected, causing delays in the visualization of real‑time values.We would like to understand what could be causing this slow performance and what actions we can take to improve the responsiveness of the OPC UA communication. Specifically, we are looking for recommendations to optimize OPC UA settings, data update rates, server load, or any other configuration that could help increase the communication speed between Kepware and FactoryTalk View.

Hi,We currently have around 30 KEPServerEX installations with perpetual (node-locked) licenses on different machines. We are planning to replace those machines one by one, but we want to make sure we do the transfer correctly without risking:• losing the licenses• having them become invalid• or incurring additional costsWe understand that the standard procedure is to use License Utility → Transfer a product activation to generate a transfer request file, upload it to the PTC licensing portal, and then activate the license on the new machine.However, in our case, we do not currently have access to the original PTC licensing account / login information that was used when these licenses were activated. This is one of our main concerns.Before we proceed, we would appreciate clarification on the following:Is the above transfer procedure the correct and safe way to move node-locked perpetual licenses to new machines without penalty?Since we do not have the original account credentials, what

I have a python code that reads data from excel and sends to kepware, I am trying to set this up and setup the tags in kepware as a server, and the python as a client. This will eventually be connected to a DeltaV system which is another client, but for now I want to test my code sending data into Kepware. Which drivers should I use for this purpose?
