What it is — and why you're here
Siemens 6GK7542-5DX10-0XE0 is the CM 1542-5, a PROFIBUS DP communication module for the S7-1500 platform. It operates as either a DP master or a DP device, supporting cyclic and acyclic data exchange. Single-width compact module, mounts directly on the S7-1500 rail and draws 0.2 A typical from the 15 V backplane bus. That's a tight power footprint for a full PROFIBUS interface. Active in production — no end-of-life flags. Standard lead times apply; quote to order against an RFQ.
Mounting and connections
Rail-mounted on the S7-1500 backplane. 9-pin Sub-D socket (RS485) for the PROFIBUS cable. IP20 protection. Ambient range: -25 to +60 °C horizontal, -25 to +40 °C vertical. 129 mm deep, 35 mm wide, 142 mm tall — single slot.
