SIMATIC DP Bus Module For ET 200M

The SIMATIC DP Bus Module for ET 200M is a fundamental component of the Siemens ET 200M distributed I/O system, which serves as a highly modular and flexible solution for integrating I/O devices into PROFIBUS DP and PROFINET networks.

It's important to clarify: While often referred to as a "Bus Module," the primary component that connects the ET 200M station to the PROFIBUS DP network is the Interface Module (IM 153). The "Bus Modules" (e.g., BM 2x40, BM 1x80, BM PS/IM) are then used to physically hold the S7-300 I/O modules and connect them to the internal backplane bus of the ET 200M station.
