FAQ How do you establish a MODBUS-RTU communication with STEP 7 (TIA Portal) for the SIMATIC S7-1200?

With only one slave using the CM 1241 RS232 (physical limitation).... With up to 10 slaves one after the other using the RS422 (via CM 1241 RS422/RS485).... We will take the sample project to describe the configuration procedure in STEP 7 (TIA Portal) for communication with multiple slaves using the CM 1241 RS422/485.
