Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program ^{CODESYS Forge talk (Post)}
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

Go in Windows to this location. Right click on this file and go to properties. Is it in Read-only state? Then CODESYS cannot open in Write mode.
