CP 342-5 6GK7342-5DA02-0XE0 Siemens Communication Module

Product Description

The Siemens CP 342-5 (6GK7342-5DA02-0XE0) is a dedicated PROFIBUS DP communication processor designed for integration into SIMATIC S7-300 PLC systems. It extends the controller with a high-performance PROFIBUS interface, enabling deterministic data exchange with distributed I/O stations, drives, operator panels, and peer controllers.

This module supports both DP master and DP slave operation, allowing flexible network architectures in machine-level and plant-level automation. Its S5-compatible communication and support for PG/OP and S7 services make it well suited for maintaining and expanding existing PROFIBUS-based installations.

Engineered as a plug-in module for S7-300 racks, the CP 342-5 draws power directly from the backplane bus and integrates seamlessly into STEP 7 engineering environments. Diagnostic LEDs provide clear visibility ofnetwork and module status, supporting reliable operation and efficient troubleshooting.

Functional Scope and Typical Use Cases

The CP 342-5 (6GK7342-5DA02-0XE0) is commonly deployed in factory automation, process control systems, and infrastructure projects where PROFIBUS DP remains an established and validated fieldbus. It is especially suitable for legacy systems requiring stable long-term operation and compatibility with existing PROFIBUS devices.
