Product description
Within a SIMATIC S7-1500, the Siemens CM 1542-1 with order number 6GK7542-1AX00-0XE0 handles Industrial Ethernet communication for the controller. The compact, single-width module provides a PROFINET interface with an integrated 2-port switch. Both electrical connections are galvanically isolated RJ45 sockets. The Ethernet access operates according to 100BASE-TX and IEEE 802.3-2005 at 10 or 100 Mbit/s. Half-duplex and full-duplex operation, Auto-Crossover and Auto-Negotiation are among the documented port characteristics. At protocol level, the module covers TCP/IP, ISO-on-TCP, UDP and S7 communication. It also includes IP broadcast and IP multicast, SNMPv1 and time synchronisation via NTP. The PROFINET function can operate as an IO controller or IO device. Integration of ports X1 P1 and X1 P2 into a ring topology with MRP is also part of the device functions. These characteristics identify the variant as a CM 1542-1 communication module within the SIMATIC-S7-1500 family. Electrical power is supplied at 15 V DC through the S7-1500 backplane bus. Typical current consumption is 220 mA and power loss is 3.3 W. For horizontal installation, operation from 0 to 60 °C is specified; for vertical installation, the range is 0 to 40 °C. The degree of protection is IP20. At 35 mm wide, 142 mm high and 129 mm deep, the device follows the compact module format of the range. As a single-width module, it mounts on the S7-1500 mounting rail. Net weight is 0.4 kg. The complete order number 6GK7542-1AX00-0XE0, the designation CM 1542-1 and the stated interface and performance data are decisive for precise variant identification.
