Siemens 6GK7542-5FX00-0XE0 SIMATIC S7-1500 CP 1542-5 PROFIBUS DP PLC Communication Module

The Siemens CP 1542-5 (6GK7542-5FX00-0XE0) is a communications processor that connects a SIMATIC S7-1500 CPU to PROFIBUS DP at 9.6 kbit/s to 12 Mbit/s, operating as a DPV1 master for up to 32 DP devices or as a DP device itself. It supports S7 and PG/OP communication over a 9-pin Sub-D RS485 port, drawing 0.1 A typical from the backplane bus.

Selection Notes

As a DPV1 master this CP handles up to 32 PROFIBUS DP devices with 2048 byte of input and output address space, while as a DP device it presents 240 byte each way to a higher-level master - covering both roles from one module. Choose the CP 1542-5 over the spare-part CM 1542-5 when a full published spec sheet and current TED data are needed for a new design rather than a like-for-like replacement.

Applications

Connects SIMATIC S7-1500 stations to PROFIBUS DP networks - as master for drives, remote I/O, and sensors, or as a device reporting into a plant-wide PROFIBUS master - in installations that still run PROFIBUS alongside newer PROFINET segments.
