Siemens 6GK1141-0AA00 Communication Processor for SIMATIC S7

Core Network Communication Function

The Siemens 6GK1141-0AA00 is a Communication Processor for the SIMATIC S7-200 series PLC family. This module enables the S7-200 controller to exchange data with higher-level networks and field devices. It handles protocol processing, data buffering, and error checking to offload communication tasks from the CPU. Consequently, it ensures deterministic and reliable data exchange in complex automation architectures .

Integrated Protocol Support and Interface Flexibility

This communication module provides 16 digital input and 16 digital output points for direct device interfacing . It supports multiple industrial protocols to enable communication with HMIs, SCADA systems, and other controllers. The 6GK1141-0AA00 integrates seamlessly with the S7-200 backplane and uses standard configuration tools for parameterization . Furthermore, its compact design fits directly into the S7-200 expansion chassis without requiring additional mounting hardware.

Technical Specifications and System Details
