Hi I’m trying to make RS485 MODBUS RTU running on Codesys but I’m not sure how to configure UART2 port to make it readalbe for Codesys system.
In Codesys I’m able only to set COM port number 1…x (not the complete file path) which should be mapped to files /dev/tty1 - /dev/tty64 if I understood correctly. Hovewer UART0-3 are mapped to files /dev/ttyS0 - /dev/ttyS3 which I’m not able to select in Codesys system.
Can anybody help me?
Thank you.
