I'm a programmer and I need to communicate with a siemens S7 PLC, I'm interested in collect information about the siemens protocols, and how to use.

Thanks.

Profibus and MPI are the two protocols. There are several ways. First they make a RS232 to Profibus/MPI converter for your serial port or use the Profibus/MPI adapter card. Most HMI have MPI and Profibus driver as well as the Step 7 software. You can also look into the Ethernet communication card for the S7.
