The TCP/IP interface allows the CMU to communicate with external systems (e.g. the plant automation environment). Data can be sent or received using this interface. For example, this enables calculated values from the system to be used in an ibaPDA process data recording for process diagnostics purposes.

On a new CMU, the telegram slots in the detail view are empty and first have to be created by the user.

The CMU is capable of receiving two telegrams and sending two telegrams. To create a new telegram, see Network.

Note
	With TCP/IP telegrams, it is important that both communication partners have identical parameterization in terms of the number of channels and the associated number of bytes. Otherwise, the received data cannot be correctly interpreted and you will obtain implausible values.
