SIEMENS 6GK7242-5DX30-0XE0 Product Description

Overview

SIEMENS 6GK7242-5DX30-0XE0 is the CM 1242-5 PROFIBUS DP slave communication module for SIMATIC S7-1200 PLC system. The SIEMENS 6GK7242-5DX30-0XE0 expands the S7-1200 controller with PROFIBUS DP slave interface to realize data exchange with PROFIBUS DP master stations. This CM 1242-5 communication module serves as a reliable Siemens S7-1200 PROFIBUS DP slave module, widely used for connecting S7-1200 to legacy PROFIBUS automation networks in factory automation and process control systems of the Siemens S7-1200 PROFIBUS DP slave module.

Features

This SIEMENS 6GK7242-5DX30-0XE0 adopts rear bus connection with S7-1200 CPU, powered by the PLC backplane bus for the Siemens S7-1200 PROFIBUS DP slave module. It is equipped with one 9-pin D-sub RS485 PROFIBUS interface, supporting transmission rate from 9.6 kbit/s up to 12 Mbit/s. The module supports standard PROFIBUS DP slave protocol, easy configuration via TIA Portal software. Status LEDs on front panel enable quick diagnosis of bus communication and module state. The SIEMENS 6GK7242-5DX30-0XE0 features compact modular design, simple hot insertion and replacement, compatible with standard S7-1200 rack layout. It helps integrate modern S7-1200 controllers into existing PROFIBUS DP networks without replacing the whole control system of the CM 1242-5 communication module.

Specs

The SIEMENS 6GK7242-5DX30-0XE0 series: CM 1242-5 PROFIBUS DP slave module. Compatible CPU: SIMATIC S7-1200. Interface: 1 x PROFIBUS DP, 9-pin D-sub female connector. Transmission speed: 9.6 kbit/s ~ 12 Mbit/s. Power supply: 5V DC from backplane bus. Power consumption: 0.75W. Mounting: S7-1200 rail side expansion. Protection rating: IP20. The SIEMENS 6GK7242-5DX30-0XE0 complies with IEC 61158, CE and UL standards as a CM 1242-5 communication module.

Principle

SIEMENS 6GK7242-5DX30-0XE0 acts as a DP slave node on the PROFIBUS network. The SIEMENS 6GK7242-5DX30-0XE0 exchanges process data with DP master through RS485 bus, and transmits data between PROFIBUS side and S7-1200 CPU via internal backplane bus. The module handles PROFIBUS protocol stack independently, cyclically sending output data to the master and receiving input data from the master. The PROFIBUS RS485 differential bus structure of the Siemens S7-1200 PROFIBUS DP slave module improves anti-interference performance for long-distance field communication.

Applications

This SIEMENS 6GK7242-5DX30-0XE0 is widely used in production lines, packaging machines, conveyor systems and process plants with existing PROFIBUS DP networks. It is applied for connecting S7-1200 PLC to PROFIBUS master controllers, DP drives and remote I/O stations. It is used for system upgrade and spare replacement of legacy PROFIBUS automation projects. The SIEMENS 6GK7242-5DX30-0XE0 delivers stable PROFIBUS DP slave communication for S7-1200 PLC in hybrid new and old automation networks as a proven CM 1242-5 communication module.
