Kepware

Hello Everybody,I'm trying to connect Kepware OPC-UA Client driver to remote OPC-UA Server to read about 50K tags.It looks like the communication is too slow and other client, that connects to Kepware and read these tags experience read failures and doesn't read all of them and about 50% of tags signed with bad values. Event log of Kepware filled with lot of events like "The subscription id is not valid.",Status code = 0X80280000.(At the attached picture)Is it anywhere recommendations about good configuration practice on OPC-UA Client driver?And what are the sizing recommendations (amount of tags, devices and channels) for Kepware server?Thanks a lot

Hi everyone,I’m encountering a recurring issue with KEPServerEX v6.16.203.0 using the Modbus TCP/IP Ethernet driver. At random times, the following popup appears:“Runtime connection lost, reconnect?”This causes temporary communication drops with Modbus devices on the network.System details:KEPServerEX version: 6.16.203.0Driver: Modbus TCP/IP EthernetNetwork: Local Ethernet, no packet loss or network faults observed Has anyone experienced this kind of issue?Could it be related to the Security Policies Plug-in or licensing constraints?Are there any recommended settings to make the Runtime more stable? Any help or insight would be appreciated. Thanks!

How do I configure a static tag for basic MID001 start communication with a Cleco Controller using OPEN PROTOCOL? OPC quick client confirms I have connectivity to the controller, shows me the IP address configured. But everything I try to setup a basic tag for MID001 to transmit a 20Byte sequence fails. I created two static tags but I can't make them read/write, are read only. Doesn't let me set a value to send to the controller.  And Controller name is not reading anything back from controller.  

I am currently working on integrating a GE Fanuc 90-30 PLC with Kepware and have encountered an issue I’d like your assistance with.I have successfully connected to the PLC using the GE SNP driver in Kepware through a direct USB-to-RS422 interface (specifically, the IC690USB901). Communication works as expected in this setup.However, when I attempt to connect to the same PLC using a USR-N510 Ethernet-based serial gateway, I selected the GE Ethernet driver in Kepware, but the connection does not work.Unfortunately, the GE SNP driver in Kepware does not seem to support Ethernet encapsulation (serial-over-IP) directly, Any guidance or documentation on this would be greatly appreciated.

Hello Forum Members,Is there any methode to setting OPC DA Client and DCOM setting in windows server 2022? I do setting dcom from kepserver manual book and only can browse OPC server tag. after import and look at quick client, all value in " BAD ".Anyone can help?

Hi community,I need to automate a KEPServerEX installation but also want to enable the Configuration API at the same time, so it cannot be forgotten. Is there a way to specify this in the KEPServerEX6.ini file during installation or is there a way to manipulate the [Config API Service] in the C:\ProgramData\Kepware\KEPServerEX\V6\settings.ini file? All comments an insights are much appreciated!   

on the Logix platform, why would @MODE work as a tag  but @IsPresent will not pass Syntax check?  Both are valid. (v6.12)

Hello Community,This happen on Kepserver 6.17 when i browse tag on OPC server. after selecting tag and hit " apply " button then there is warning "One or more changes were not applied to 'Wincc.HIPC11SVR' since it is being referenced by a client.". i read manual but no solution. is there anyone can help?

It is also likely to cause issues with other third party MES Software, which really does not like reading from, or writing to addresses that are "Bad (Out Of Service)" .   Is there anything I can do to remedy this situation? ie, Is there a way to make sure I can identify situations where Kepware is unable to subscribe via MID51, seperately from situations where Vehicle ID Number is simply blank? Alternatively, can I change how Kepware determines a address is "Bad" I am in the same situation, looking at the same issue. We currently have to restart the KepServer regularly. Having most of the tags from the AtlasCopco default to Bad(Out of Service) Quality leads to huge issues on the OPC-Client side.Is there a solution for this or a related Knowledge Base or Support Article?   Reference topic for the quote: https://community.ptc.com/t5/Kepware/Question-regarding-PF6000-and-how-KepwareOPC-sets-the-JOB-JOBNUM/m-p/986634#M2551 Thanks!

I have a situation that I am trying to understand to see if this actually can be done. I have a FactoryTalk View application with a Numeric input that is scaled from -0.5 to 0.5 but it is writing directly to the Kepware Tag and is linked to a Modicon Register. I am not scaling the -0.5 to 0.5 in the hmi, I would like Kepware to perform that. So Ftalk input would be -0.5 to 0.5 and then Kepware would scale the -0.5 to 0.5 to 0 - 4095 and write 0 - 4095 to the Modicon PLC. Can this be done?

Hello Community!Can anyone give me a clue why does this happen. It worked but after some time it doesn't. See the image below. I already followed this error solution steps. However, this error still showing up. The concept is about connection of PLC simulator V15.1 of PLC 1200 to Kepware.I tried using NetToPLCssim if this the case but still the error persists. 

Dear Experts, We have several controllers on the network and we would like to collect data from them in parallel, so that we keep the Omron scada intact. The controllers are of type CJ2.We are testing with the trial version of KepserverEX 6 and for now we are testing the connection with only one controller.The controller data is as follows:Fins destination addressIP: 10.0.0.43Network: 3node: 43unit:15frame Length: 2028        The error is as follows: Date Time Level Source Event10.07.2025 09:57:03 Warning Omron FINS Ethernet Omron.ABC3 | Device responded with network relay error. | Net address = 003, Node address = 043, Main error = 0X10, Sub error = 0X5, End code = 0X9005. I also tested the connection directly to the PLC (disconnected the connection to the SCADA system) and we had the same error. What did we set wrong? Thank you and best regards

Good day.   I have exactly the same issue but in UDP. and sending data. I need to send two data in an ASCII telegram over UPD IP and UCON just stops sending after 5mn, 1 h, or 1 day or more. Nothing in the logs.   Best regards   Reference topic: https://community.ptc.com/t5/Kepware/UCON-Driver-TCP-IP-Stops-Collecting-Data/m-p/956202#M2072 

I have setup a BACNET device in Kepware....  How do you make the Tag Objects discoverable when a device tries to connect to the Kepware BacNet device ?

I am using PTC-Kepware evaluation copy to generate OPCUA Simulated data and it's working fine for customer demos. Many customer demands MODBUS RTU / TCP Simulated data from PTC-Kepware tool. 1. Is PTC-Kepware support MODBUS simulation?2. Where can I get training videos of Kepware tools?  

Is there a limit on the number of license transfers allowed for KEPServerEX?

I know the idea of using REST Client is to push data that makes sense and let the REST Server handle the other side of things. Howerver, the "otherside" in my case isn't as flexible. And the usecase am in, things will work only if the "|SERVERDATE|" send the actual date in yyyy-mm-dd formatAnywhere around having other handlebars variables to be used outside the |VALUES| part of the advanced template?

Hi, Any idea on how to reset or change the password? 

Hi, I have issue reading reading higher address from the same DB for Siemens TCP/IP driver (S7-400).I'm able to read e.g. DB15.INT3334 but not DB15.INT3396. The error code is "Unable to read data from device. | Data block = 'DB15', block start = 3396, block size = 2, Reason = 'Device returned data access error'. Error code = 0X5". I have tried the following but still doesn’t resolve it.PDU size of 240, 480, 960Increase request timeout from 5000ms to 10000msRedownloaded DB15I have another model 410-5H which can read such high address unlike 417-4.Is there any settings in CPU properties which limit the read address memory?Does anyone faces such issue?

I am trying to setup a MODBUS TCP server in Kepware.   I have defined ModBus Addresses such as 40001 in Kepware and am trying to access the data from a MODBUS client.... and it is NOT connecting...  Can this be done /or/ is Kepware's Modbus TCP driver only a Client ?

Hello,We are currently facing a challenge with our MES system's interaction with the Kepware OPC UA server, and I would like some guidance or clarification regarding logging and troubleshooting capabilities.Setup:Kepware Version: 6.15.132.0Kepware ServerEX 6 with multiple channels configured for MODBUS devices.MES system is connected to the Kepware OPC UA server.MES subscribes to specific device tags, but values do not automatically update in MES as expected.MES is configured to read/update these tags every 60 seconds.Problem:Without any other client connected, MES does not consistently receive updated tag values.However, when I open the Kepware Quick Client (or connect another OPC UA client such as OPC Router or UaExpert) to the same tags, the MES system suddenly starts receiving updated values again.This behavior suggests that connecting a third-party client somehow triggers or "wakes up" the tag updates.Investigation So Far:We have consulted our MES supplier, and they insist that th

I work with Howmet Aerospace, and we recently activated a couple of Kepware licenses for a couple of interface machines. Unfortunately, the local support mistakenly wiped those machines and repurposed them, thinking they weren't in use or something. So, we lost those Kepware licenses and cannot access the machines to transfer the licenses. I still have the request and response files from when we activated the licenses last, if that helps. I don't know exactly how to put in a support ticket.  I tried to navigate the site on my own and create one, but I kept getting stuck.  If you need more info from me on our product information, I can gladly give whatever you need.  If this isn't the place for this issue, I would at least appreciate being pointed in the right direction.  Thank you!

Hi new poster here,Im trying to connect a Turck I/O module to my KepserverEX 6 like the subject says, but I dont know whether that is possible. I tried using the Allen-Bradley ControlLogix Ethernet as my driver , and selected the ControlLogix 5500 model for my device, but i cant seem to create tags for it.  Please advise, thanks.
