      You need to ask Weintek if they support the licensing. For Softmotion the device should be realtime capable.

      My CODESYS OPC UA server provides endpoints using both the hostname and the IP address. Connecting via the IP address works fine, but connecting via the hostname does not. The endpoint list shows both opc.tcp://<hostname>:4840 and opc.tcp://<ip>:4840. When using the hostname, the OPC UA client (UA Expert) fails to connect. Using the IP address connects without issues. Main goal is to conect via Python but opcua-asyncio seems to prefer the hostname. How can I configure CODESYS or my system so that the OPC UA connection via hostname also works properly or disable it completly? Running Codesys for PFC200 sl 4.18.0.0

      Has anyone tried sending live sensor data from an ESP32 into a CODESYS runtime (for example via MQTT gateway or a Modbus bridge) to trigger PLC logic? I was reading an ESP32 → MQTT tutorial (https://www.theengineeringprojects.com/2021/11/esp32-mqtt.html) that shows how easy it is to publish sensor data from an ESP32, and I’m wondering how practical that is when tying the stream into industrial control software like CODESYS. I’ve also seen Arduino forum threads where people relay sensor streams to MQTT brokers and Raspberry Pi projects that bridge MQTT→Modbus, so I’m mainly curious about real-world issues: reliability, message latency, and simple patterns you’d recommend for safe PLC integration. Any tips, examples, or gotchas from folks who’ve done this?

      I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

      Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

      Hi, Got same problem, appeared after 4.3.1.0 update. Prabably problem is in performance. I am using virtual machine, so adding one more core and several GB to RAM still not solved, but atleast did system more stable. Try optimise your main program or set less task interval. Regards, I will be your mate in solving this mistery =)

      We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

      You can use the (open source) FTP client in Forge. This works on 64 bit systems. See: https://forge.codesys.com/prj/ftp-client/code/HEAD/tree/ As this is open, the idea is that when you use it and make improvements to the source code, that you also commit this in a branch so others can also benefit from it.

To search for an exact phrase, put it in quotes.  Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it.  Example: docs -help
To search on specific fields, use these field names instead of a general text search.  You can group with AND or OR.
