z The basic identifiers of PDO1-Rx and PDO1-Tx are pre-assigned in such a
way that they can exchange data with the process data objects of
CAN-IN3/OUT3 of a controller.
z The basic identifiers of PDO2-Rx and PDO2-Tx are pre-assigned in such a
way that they can exchange data with the process data objects of
CAN-IN2/OUT2 of a controller.
