Product information
The 6ES7288-5CM01-0AA0 is a Siemens SIMATIC S7-200 SMART communication module: CM 01, RS 485, with a 9-pole D-sub (pin) connector, supporting Freeport communication. It adds one RS 485 interface to an S7-200 SMART CPU.
The module occupies a compact footprint of 35 × 52.2 × 16 mm and weighs approximately 18.2 g, drawing typically 50 mA from the 5 V DC backplane bus with a power loss of 0.5 W. Note that this module does not provide PROFINET, PROFIBUS or Ethernet TCP/IP — it is a serial RS 485 interface for Freeport and similar serial protocols.
