It supports both DPV0 and DPV1 profiles, so it handles cyclic data exchange and acyclic parameter/configuration data — the full PROFIBUS feature set for drives, remote I/O, and intelligent slaves. The module draws 0.1 A from the 15 V backplane bus, dissipating 1.5 W — a light thermal load that keeps the enclosure temperature rise low even in a densely populated rack. ## Panel fit and integration constraints It is a compact S7-1500 single-width module — 35 mm wide, 142 mm high, 129 mm deep — and snaps onto the standard S7-1500 DIN rail mounting rail. The PROFIBUS interface is a 9-pin Sub-D socket (RS485) on the front, so the cable connector must be a standard PROFIBUS male plug with termination resistor access. Horizontal installation allows 0 to 60 °C ambient; vertical installation derates to 0 to 40 °C — plan the cabinet airflow accordingly if the rack is mounted vertically. Engineering requires STEP 7 Professional V12 SP1 (TIA Portal) or higher for configuration; the module is not configurable with older versions.","metaTitle":"Siemens 6GK7542-5FX00-0XE0 CP 1542-5 PROFIBUS DP Module","metaDescription":"Siemens 6GK7542-5FX00-0XE0 CP 1542-5 communications processor for S7-1500.
