Product Description for Siemens 6GK7342‑5DA03‑0XE0 (CP342‑5 Communication Processor Module)
1. Product Overview
6GK7342‑5DA03‑0XE0 is a new‑original Siemens SIMATIC NET CP342‑5 communication processor designed exclusively for the SIMATIC S7‑300 PLC system. It is installed on the S7‑300 back‑plane rack and acts as an independent PROFIBUS‑DP communication gateway. It connects S7‑300 CPU with ET200M, ET200SP distributed I/O modules, frequency converters, HMI panels, S5‑series PLC and other PROFIBUS‑DP compliant field‑bus devices. It can work as either a PROFIBUS‑DP master station or DP slave station, offloading communication tasks from S7‑300 CPU so that the main processor can focus on logic control tasks only. It supports S7 basic communication, PG/OP online programming and diagnosis and S5 compatible data exchange. This module is widely applied in automobile production lines, packaging equipment, metallurgical workshops, cement production plants and wastewater‑treatment systems adopting PROFIBUS‑DP field‑bus networks. It is configured and diagnosed by STEP7 engineering software and powered by S7‑300 back‑plane bus plus external DC24‑V power supplydocs.rs-on….
2. Main Functions
- PROFIBUS‑DP Master‑Station Function
When running as DP master, it can connect up to 124 DP slave devices. The total input and output address space reaches 2160 bytes respectively, with maximum 244‑byte input and output data for each single slave device to process mass field‑side signal transmissiondocs.rs-on….
- PROFIBUS‑DP Slave‑Station Mode
It can operate as a DP slave to exchange data with upper‑level DP master controllers such as S7‑400 and S7‑1500 CPUs for cross‑level PLC data interaction.
- Multiple‑Type Communication Service
It supports S7 communication, open user communication via SEND‑RECEIVE function blocks with maximum 16 communication connections and 240‑byte user data per connection. It also realizes data exchange with old‑style S5 PLC systems for equipment upgrade projectsdocs.rs-on….
- PG‑OP Online Diagnostics
Programming computers and HMI panels can access the whole PROFIBUS‑DP network through this CP module for program downloading, online monitoring, parameter setting and fault diagnosis without extra network adapters.
- Built‑in Comprehensive Diagnostic Function
LED indicators including SF, BUSF, RUN and STOP display module status, bus failure and hardware faults. Detailed diagnostic information can be uploaded to S7‑300 CPU and read via STEP‑7 software for fast troubleshooting.
- Galvanic Isolation and Anti‑interference
RS‑485 electrical isolation is built‑in between internal back‑plane bus and PROFIBUS‑DP circuit to restrain electromagnetic interference generated by servo drives and high‑power motors.
- Multi‑module Deployment
A single S7‑300 rack can install up to four CP342‑5 modules to build multiple independent PROFIBUS‑DP networks for large‑scale distributed automation projectsdocs.rs-on….
