Siemens 6GK7242-5DX30-0XE0 Communication Module

Siemens 6GK7242-5DX30-0XE0 is the CM 1242-5 PROFIBUS DP slave communication module that enables a SIMATIC S7-1200 controller to join a PROFIBUS DP network. It provides a single PROFIBUS DP slave interface via a 9-pin Sub-D RS-485 connector and supports speeds up to 12 Mbit/s. The module is powered from the backplane at 5 V DC, drawing typical 0.15 A with a power loss around 0.75 W. As a DP slave, it supports DPV0 and DPV1 services and allocates 240 bytes for input data and 240 bytes for output data in the DP communication cycle. Configuration software is required to set up the module within a SIMATIC system. The CM 1242-5 is designed specifically for electrical connection of SIMATIC S7-1200 controllers to PROFIBUS as DP slaves, enabling integration into existing PROFIBUS DP installations.
