The 6GK7542-5DX00-0XE0 (CM 1542-5) is a high-performance PROFIBUS communication module for Siemens SIMATIC S7-1500 automation systems. Equipped with a 9-pin Sub-D interface, it supports transmission rates from 9.6 kbit/s to 12 Mbit/s and is primarily used to connect S7-1500 controllers to a PROFIBUS DP network. As a DP-V1 master or slave, this module fully supports S7, PG/OP, and Open User Communication (OUC) protocols, providing data group routing and diagnostic functions to improve data exchange efficiency in industrial networks.
The module interconnects via the S7-1500 backplane bus and integrates a separate processor to handle the underlying protocol stack, thus reducing the computational burden on the main CPU. During operation, the module receives backplane commands and uses RS485 differential signaling technology to establish a bidirectional data transmission link between the PROFIBUS network and the master control system.
The 6GK7542-5DX00-0XE0 Siemens CM1542-5 Communication Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Module Model: CM 1542-5 (Communication Module)
Bus Protocol: PROFIBUS DP (Supports standard DP-V1 master function or operates as a DP slave).
Physical Interface: One 9-pin Sub-D socket (RS485 interface connection).
Transmission Rate: Dynamically adjustable, ranging from 9.6 kbit/s to 12 Mbit/s.
Connectivity: Supports up to 125 DP slaves operating simultaneously.
Power Supply: 15 V DC power directly from the S7-1500 backplane bus (typical current consumption is 0.2 A).
This module, acting as a dedicated processor, offloads heavy industrial communication traffic from the main S7-1500 CPU:
S7 and PG/OP Communication: Supports secure data exchange with older S7 platforms, engineering PCs (STEP 7 / TIA Portal), and operator HMI touch panels.
Data Logging Routing: Allows you to transparently transfer parameter logs from the central PROFINET engineering environment to fieldbus-level PROFIBUS devices (such as smart meters or motor drives).
FDL Communication: Supports fieldbus data link protocols, enabling lightweight, offline, local data telegraph exchange with third-party automation equipment.
Time Synchronization: Acts as a time master or slave on the physical PROFIBUS segment to maintain consistency of diagnostic timestamps.
