The Industrial Raspberry Pi Forum

Dear all，

I know CODESYS supports multiple serial ports at the same time, but the CODESYS serial port label is COM and the Raspberry Pi serial port label is /dev/tty, what do I need to set to implement the Raspberry Pi serial port mapping so that it matches CODESYS.

Best regards,
Cade

Dear,

Thank you very much for your help. But now I am facing a problem: I tried to find the serial port number and the command "ls -l /dev/serial*" did not find the serial device. How should I find my serial device?

Best regards，
Cade
