Communication relationships of the process data channels

Regardless of the process data to be transmitted, the communication relationships of
the process data channels must be defined. The connection of PDO channels is done
via the assignment of the identifiers. The identifiers of Rx-/Tx-PDO must match in
each case.
Generally, there are two possibilities:
-
-
This process is documented in a tabular form via a communication relationship
list.

All the TxPDOs used must have different identifiers !!!
The Identifier must be clear in the system bus network.
