Hello,
I have an RFID reader that is detected as a keyboard. While looking for information, I came across examples using visualization. I would like to read the ID without visualization or external code in python, only in PLC.
I found on the forum that you can try reading directly from potru /dev/...
https://forge.codesys.com/forge/talk/Runtime/thread/24b3527036/
How to read values directly in codesys? Or maybe there is another solution?
Best Regards
