Siemens 6ES7 135-4FB52-0AB0 DP Interface Module

Siemens 6ES7 135-4FB52-0AB0 is a SIMATIC ET 200S DP interface module that functions as the PROFIBUS DP master interface for the ET 200S remote I/O family. It provides the DP master connection between ET 200S I/O blocks and a PROFIBUS DP network, enabling structured, cycle-based data exchange with a central controller. The module is cataloged under the ET 200S DP master interface designation with the exact part number 6ES7 135-4FB52-0AB0, and Siemens documentation and conformity records identify it as the DP master interface component of the ET 200S system. In typical automation architectures, this interface coordinates communication with attached ET 200S devices across the PROFIBUS DP fieldbus, supporting centralized monitoring and control of distributed I/O. As part of the SIMATIC ET 200S ecosystem, the DP master interface is designed to integrate with other ET 200S modules to form a scalable distributed control network. For installation, wiring, and configuration, users rely on Siemens’ ET 200S manuals and the SIMATIC documentation set corresponding to the 6ES7 135-4FB52-0AB0 part number. This module is suited for replacing or upgrading DP communication in ET 200S-based systems and is referenced in industry documentation as the DP master interface component of the ET 200S lineup.
