Communication modules/processors
For special requirements of your plant, use communications processors (CPs) for security
functions to secure Industrial Ethernet networks.
If your system requires additional interfaces, communication modules (CM) expand your S7-
1500 CPU with other interfaces of an interface type such as PROFINET, PROFIBUS or
point-to-point connection. The CMs for point-to-point connection allow, for example, Freeport
or Modbus communication via their RS232, RS422 and RS485 interfaces.
