Communication Relationships Of The Process Data Channel - BONFIGLIOLI actice Instruction Manual

4.11.4
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.
There are two principal possibilities:
This process is documented in a tabular form via a communication relationship list.
Example:
Attention! All the TxPDO's used must have different identifiers !
