Siemens 6GK7342-5DA03-0XE0 Communication Processor

The Siemens CP 342-5 communications processor (6GK7342-5DA03-0XE0) connects SIMATIC S7-300 controllers to PROFIBUS DP, delivering S5 compatibility and enabling PG/OP and S7 communication across the network while serving as a dedicated interface bridge between the controller and field devices. This spare-part module provides a single PROFIBUS DP interface featuring a 9-pin Sub-D RS-485 socket for the bus and a 4-pin terminal block for the external 24 V power supply, with 5 V supplied from the backplane to the processor. Data throughput on the PROFIBUS interface ranges from 9.6 kbit/s up to 12 Mbit/s, and there is no Industrial Ethernet interface on this model, aligning it with classic PROFIBUS-based automation setups. Designed for SIMATIC S7-300 ecosystems requiring dependable PROFIBUS DP connectivity and compatibility with S7 and S5 communications, the CP 342-5 also supports PG/OP access to connected devices and simple integration into existing control architectures.
