I need to communicate with a black box wich can communicate with Modbus. My PLC is a S7-300 series and a CP340 communication card.
I have an example for Modbus Slave RTU but not for Modbus Master RTU. Who can provide me with a Modbus Master RTU protocol for Siemens S7-300/S7-400?
Thanks in forehand!
