hi. i got one master and 6 slave PLCs communicating with radio modems(RS232/485) and CP341-RS232c cards on the PLCs.
Modems are addressable and can work as multipoint network.
but can i address the output data from modem to RS232 card?
How can i realize that which PLC is sending data now?
Do i need to change my cards?
