Siemens 6GK7542-1AX00-0XE0 Communication Module

Siemens 6GK7542-1AX00-0XE0 is a CM 1542-1 (S7-1500) communication module that provides Industrial Ethernet / PROFINET connectivity for SIMATIC S7-1500 PLCs. It offers 2 × RJ45 Ethernet ports (10/100 Mbit/s) and supports TCP/IP, UDP, ISO-on-TCP, and S7 communication, with SNMPv1, multicast, and NTP time synchronization. Power is supplied via backplane bus (approx. 15 V DC), with current consumption ~0.22 A and power dissipation around 3.3 W; it mounts on DIN rail and has IP20 protection, weighing roughly 0.35–0.36 kg. Commonly used in industrial automation networks, manufacturing plants, energy management systems, water treatment facilities, and process industries to enable secure and high-speed data communication between PLCs, SCADA systems, HMIs, and enterprise networks, including diagnostics and remote access.
