Kepware

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

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? 

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.

Hello everyone! Is there any way to use the service without any type of authentication? Every time I access the API, I need to use the Administrator account, but I would like a simpler method for access. Thanks!

@dmandersen  With reference to topic (Kepware/MT-Connect) Do you know if the "Assets" is supported on the driver?

Good morning,I frequently encounter the following error when connecting via OPC-UA: Date Time Level Source Event19/06/2025 13:01:03 Warning OPC UA Client B&R | Read request failed on device. | Status description = 'The operation timed out.', Status code = 0X800A0000. Thank you.

We are getting lots of tag from PLC devices (40+) to Kepware. Sometimes, due to some reason the connectivity is lost  between PLC and Kepware. So that we facing data loss issue. Is there any mechanism within a Kepware to address this connectivity loss? How to identify this connectivity loss from ThingWorx for all PLC devices?
