Overview
The module draws 5.0 W from a 24 V DC supply and is rated IP20 for in-cabinet use. Its 9-pin Sub-D socket provides the RS485 PROFIBUS interface.
Applications
This communications processor is used in SIMATIC S7-300-based automation systems where the controller must participate in a PROFIBUS network as an FMS or S7 communication node. Typical installations include process plants, material handling systems, and machine cells that use PROFIBUS for distributed I/O, drives, and operator panels.
Integration & mounting
The module occupies a single slot in the S7-300 DIN-rail mounting rack. Its dimensions are 40 mm wide, 125 mm high, and 120 mm deep, with a weight of 300 g. The IP20 rating means it must be installed inside a cabinet with a minimum protection enclosure. Supply is 24 V DC via the backplane bus; no separate power connection is needed. The 9-pin Sub-D connector faces the front of the module, accessible after the front panel is opened.
