How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Siemens CM 1542-1 (6GK7542-1AX00-0XE0) is a communications module that connects a SIMATIC S7-1500 CPU to PROFINET as an IO controller or IO device, supporting TCP/IP, ISO-on-TCP, UDP, and S7 communication over two RJ45 ports at 10/100 Mbit/s. It adds IP broadcast/multicast, SNMPv1, and NTP time synchronization, and weighs 0.36 kg.
As a spare part, this CM covers baseline PROFINET connectivity for an S7-1500 station - TCP/IP, ISO-on-TCP, and UDP open communication plus S7 communication as either an IO controller or IO device. Choose it when a station needs a second or replacement PROFINET port without the PROFIBUS DP interface the CM 1542-5 modules add.
Adds a PROFINET interface to SIMATIC S7-1500 stations exchanging data with other S7 controllers, HMI, or SCADA systems over TCP/IP or S7 communication.
