Kepware

Hi guys, I'm trying to pull data from 3 different Rockwell PLCs, however the data is reading and writing incredibly slow! I added the PLC to another Kepserver and it polled the data instantly. Any ideas what I'm doing wrong and why it is so slow? KepServerEX 6.17, V6 17.240.0

when uploading the license activation response, I get an error that trusted storage is not available. Please help me 

I'm using kepware datalogger. I have configured different DSN for different table login purposes. All the loggers were working fine in the application server. And suddenly this happening randomly for dataloggers Unable to query recordset on Log Group Reason: ConnectionWrite (send()).General network Error. Does anyone have any idea what this error means and how to resolve it ? Already the application is in live mode. But this is happening randomly. Network side everything was good having good ping.  

No errors that I know of but the server was rebooted around 7pm last night and the Ignition HMI server could not get any data until I logged into the KEPServerEX server and opened the KEPServerEX Configuration client. I did nothing else, This has happened before. How do we make sure that the OPC UA connection survives a reboot?

Hi I've one lincoln electric(Arc Tracker) device which supports ethernet communication, which has LTAPP protocol for their application to talk over it. How can i get those data in kepware using LTAPP?

I’m having trouble testing the Kepware server with Python and OPC UA because there’s no way to set an admin password. This makes it tricky to test authentication properly and get my scripts to work the way they’re supposed to.What I Need:It would be super helpful if there was an option to set an admin password so I can:Test Python scripts using the OPC UA library with proper authentication.Simulate secure setups for OPC UA workflows.Make sure everything works like it would in a real-world environment.Why It’s a Problem:Without an admin password, I can’t properly test authentication, which makes it hard to validate my scripts or simulate real-world scenarios. It’s holding me back from getting everything running smoothly. Anyone have a suggestion? I just need to gather synthetic real time data to push to 3d models in USD 😃 

Hy, I'm currently adding several OMRON PLC's (CS1G-H), all of the same type and equipped with the same Ethernet card (EIP21). One of the PLC's is working fine, but the other two are not collecting data. The only noticeable difference is the unit number for the Ethernet card. The working PLC has the default unit number set to 0, while the others are set to 2 and 3. Do I need to adjust this in the FINS protocol settings to resolve the issue? 

Has anyone had any luck pulling data from Yaskawa robot controllers using a Kepware Driver?

 Hello,I am experiencing issues while trying to connect to an OPC UA server using KEPServer. Below are the errors I encountered in the logs:  Date Time Level Source Event 11.12.2024 14:56:46 Warning OPC UA Client OPC UA CLIENT | Socket error occurred connecting. | Error = 10060, Details = 'A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.'. 11.12.2024 14:56:46 Error OPC UA Client OPC UA CLIENT | Channel failed to connect. | Status description = 'Could not establish a network connection to remote server.', Status code = 0X80AC0000. Additional Information:Server Address: opc.tcp://10.20.20.113:4840Username: orecifua1Password: (Provided during setup)Network: I have multiple network adapters and I am trying to ensure the connection uses the correct adapter.Despite ensuring the server is reachable via ping, the OPC UA client fails to estab

Hello, I'm trying to read the tag values from CSV file to KEPServerEX Channel/Device. The reading is basically working and I can see the tag values which are written in CSV.But here comes a problem: When I want to update values in CSV I get an error that the CSV file is locked. How can I change the tags valeus in CSV to get new values in the KEPServer EX? BRTomaz  

We cannot connected the Kepware sever to the DxP(OPC UA client) using  "Basic256 sing"But We connected the Kepware sever to the DxP(OPC UA client)successful on no security. When I turned on encryption, the following error occurred on the client side."Selected security is not found in server endpoints"Please tell me what to check. 

We are running KepServer to monitor our equipment, but we are having frequent disconnection of the system causing data monitoring loss. When we Re-Initialize KepServer, I get the below error I am not sure what to do to correct this issue  

Hello, I have a multiple PLCs in the operation lines. Each PLC has operation data from single or multiple machines. I read data from them in a single KEPServerEX. From there I am reading data in a Linux server with the help of a Python script which uses asyncua and asyncio to read data and then it stores in a postgresql database.I read data from Kepware in 1 second interval. But sometimes I lose data from any of the machines which is connected to the PLC where as data from other machines are fine. Problem is that everything will be fine for hours and suddenly we lose data from any of the machine. There is a single python script to read all data. asyncio parallel execution method is applied to read data from all machines at a time. When terminate the python code and execute it again everything becomes normal. Can you please say what could be the probable issues and how to fix that. 

Hello, Our company's custom MES application uses an Oracle database on the backend and connects with the shopfloor PLCs using the KEPServerEX OPC server. We plan to migrate the MES application (Full-stack - database + Middleware + UI) and the OPC server machine to Oracle Cloud. Below are the existing configurations: Oracle database 12c Rel 2OPC ServerWindows Server 2019KEPServer EX 6.9.584.0Oracle Instant Client 12cOracle ODBC Driver 12cAs part of the migration, we want to upgrade the Oracle database to 19c and switch to the Oracle Autonomous Transaction Processing (ATP) database. We have set up the ODBC connection using the Oracle 12c ODBC driver and instant Client 19c (we also tried the 12c client). KEPServerEX can connect to the ATP database; it can read but not write.  Desired Future ConfigurationsOracle ATP database 19cOPC ServerWindows Server 2022KEPServer EX 6.17.240.0 (The older version 6.9.584.0 cannot even read from the Oracle database)Oracl

I am looking to evaluate multiple tags in my Advanced Derived Tag with a String output.  I would like the output to be the following machine states: "Running" or "Idle" or "Down".  Is this possible?

Good afternoon. KepServerEX V5.21 I would like to implement a periodic backup of the runtime project: is there a method to do this via the command line by running a batch script or using API calls? RegardsPaolo 

We want to send data of all the tags to iot gateway only when value for 1 of the tags changes using kepserverex 6.15 version. We've tried combinations of publishing on intervals(wide format as well as narrow format) and on data change using Every Scan and On Data Change option for each iot gateway tag. How can this be achieved using advanced tags(linked tag or derived tag) or is there any other alternative to this?

HiWe need to capture the timestamp property of a PLC tag through advance tags module.   We need  the hour in which the data of one tag has been changed..  How can we do it?   We are using kepserverEX  v6.16.203.  Thanks in advance

I've made a Kepware configuration for about 10 Rockwell plc's. But i have an error on one of them. All other 9 are working fine.It is a 1756-L72 CPU where i have issues to connect with. We've a working connection to another PLC with the same configuration which is working fine.I don't see an error message in the diagnostic list of Kepware. what is the best way to proceed with this to find a root cause and a solution?

Hi Support,  I am trying to filter out tags during an import. Could you please provide some examples of how the leaf filtering works. I have tried different itereations and get the same results eavh time.  Thanks

Hi,Is there a possibility to stop KepserverEx + Siemens S7 Plus Ethernet from loading symbols from the PLC every time a client connects ? This takes a very long time for every client connection and really is not needed for my use case (All necessary static tags where manually added).I already disabled following settings on the PLC node:- Tag Generation / On Device Startup = Do Not Generate on Startup- Communications / On Invalid Tag = Disable
