The Modbus protocol has been on the market longer than almost any other transmission standard in industrial communication. It is based on a master/slave or client/server architecture, and it is effective and easy to implement. Modbus is con-nected to PROFIBUS DP by means of the SIMATIC ET 200M distributed I/O using the CP 341 communication module. This module permits fast, high-performance data exchange via a point-to-point connection.
