SIEMENS Connecting system SIMATIC S7 Introduction

SIMATIC S7

PROFIBUS communication for SIMATIC S7

The communication modules for SIMATIC open up further application cases through additional functions using CPs, such as Fiber Optic, as far as the terminal device. They also support versatile expansion of the SIMATIC with further communication interfaces for PROFIBUS  as required, taking the load off the CPU.

Standard functions – PROFIBUS connection for any CPU
  • CM 1242-5 and CM 1243-5 for SIMATIC S7-1200 for connection to PROFIBUS as DP slave or DP master
  • CM 1542-5 for SIMATIC S7-1500 for connection to PROFIBUS as DP slave or DP master
  • CP 342-5 for SIMATIC S7-300 for connection to PROFIBUS as DP master or DP slave
  • CM 443-5 Extended for connection to PROFIBUS as DP master or DP slave
  • Designed for use in harsh industrial environments
  • Shipbuilding certification for use on ships and offshore units
  • High-speed data transfer due to transfer rates of up to 12 Mbit/s
CPs with special functions
  • CP 342-5 FO with integral optical interface for connecting the SIMATIC S7-300 to the optical PROFIBUS DP
  • CP 1542-5 as entry-level module for connecting the S7-1500 to PROFIBUS with limited number of PROFIBUS DP slaves
