Siemens Communications processor CP 1542SP-1 Part number 6GK7542-6UX00-0XE0

Product Overview

Siemens Communications Processor CP 1542SP-1 for ET 200SP / Industrial Ethernet (6GK7542-6UX00-0XE0) is a network interface module that enables a distributed I/O station based on SIMATIC ET 200SP to connect to Industrial Ethernet or PROFINET networks. It acts as a gateway between the ET 200SP backplane bus and Ethernet, allowing I/O, diagnostics, and controller communication over standard industrial network infrastructure. This module supports open-IE communication, S7 routing, and various network protocols — making it essential for integrating field I/O systems with higher-level automation, SCADA or process-control networks.

Key Features

• Communications processor for ET 200SP distributed I/O system
• Industrial Ethernet / PROFINET interface for I/O station networking
• Supports open-IE protocols: TCP/IP, ISO-on-TCP, UDP — enabling flexible network integration
• Supports S7 communication and routing (connections to S7 controllers and networked devices)
• Network services: DHCP, SNMP v1, NTP (time synchronization), IPv4 and IPv6 addressing support
• Web-server access and diagnostics for remote monitoring of I/O station health and status
• Compact DIN-rail mounting module — integrates into ET 200SP racks with minimal footprint
• Wide ambient temperature and humidity tolerance — suited for industrial environments

Applications

The 6GK7542-6UX00-0XE0 is ideal for industrial automation systems where a distributed I/O system (ET 200SP) needs to be connected to Ethernet or PROFINET networks. Typical applications include factory automation, machine control panels, process control systems, building automation networks, remote I/O installations, and SCADA-integrated systems. It facilitates communication between remote I/O modules and central controllers (e.g. SIMATIC S7), enabling centralized control, monitoring, diagnostics and data exchange over standard industrial Ethernet infrastructure.
