The Siemens 6ES7288-5CM01-0AA0 is a SIMATIC S7-200 SMART CM01 RS-485 Communication Board that provides one compact 9-pin RS-485 Freeport communication interface.
- CM01
- 1 RS-485 interface, 9-pin D-sub male
- Powered from 5 V DC CPU backplane bus, 50 mA typical
- 35 x 52.2 x 16 mm
In an S7-200 SMART automation station, it adds one RS-485 Freeport interface for project-defined serial data exchange with compatible devices. It works with the exact CPU, expansion-bus or signal-board interface, wiring, field devices, and project configuration specified for the complete article number. It is applied in serial instruments, drives, operator devices, and project-defined RS-485 machine communications.
Important Notice: Use the complete 6ES7288-5CM01-0AA0 code and verify the physical nameplate, current Siemens documentation, signal range, wiring, project, and accessories before installation or replacement.

Instrument connectivity
Links compatible serial instruments using the documented pinout and protocol implementation
Machine-device data transfer
Exchanges command, status, and measurement telegrams defined by the CPU project
Compact communication expansion
Supports serial instruments, drives, operator devices, and project-defined RS-485 machine communications
Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-5CM01-0AA0, CM01, host system, signal type, wiring, and project from the physical installation.
1
Identity: Match every character of 6ES7288-5CM01-0AA0 and the CM01 marking to the physical nameplate and project
2
Host and power: Verify Powered from 5 V DC CPU backplane bus, 50 mA typical; isolate all energy sources before insertion, removal, or wiring
3
RS-485: Verify the 9-pin pinout, cable, shield, reference conductor, termination, biasing, baud rate, and Freeport program before connection
4
Cabling: Follow Siemens terminal, shielding, grounding, separation, and maximum cable-length instructions
5
Commissioning: Verify addresses and scaling, energize one circuit group at a time, test fail-safe behavior, and record results
