4.7 Communication
4.7.1 Interfaces for communications
Interfaces for communication via PROFINET and PROFIBUS DP (as of CPU 1516) are already
integrated in the CPUs. Additional communication modules enhance the communication
capabilities of the SIMATIC S7-1500 with additional functions or interfaces, e.g. 8xIO-Link.
The following communications options are available for your automation task:

4.7.2 CM communication modules / CP communications 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.
