Compact switch module
Siemens Industrial Communication
Increase the number of interfaces directly on the SIMATIC S7, ET 200M or LOGO! logic modules at low cost: integrate machines into existing plants with the aid of the unmanaged Compact Switch Modules (CSM).
The unmanaged CSM in the respective design of the LOGO!, SIMATIC S7-1200/S7-300 or ET 200M expand the connection options thanks to their additional interfaces.
