6.4 Identifiers of the process data objects
The identifiers for the CANaux1_IO ... CANaux3_IO process data objects are generated by the
so−called basic identifier and the node address set in C2450:
Identifier + basic identifier ) node address
Basic identifiers
dec hex
PDOs CANaux1_IO (cyclic process data)
CANaux1_IN 512 200
CANaux1_OUT 384 180
CANaux2_IO (event− or time−controlled process data)
CANaux2_IN 640 280
CANaux2_OUT 641 281
CANaux3_IO (event− or time−controlled process data)
CANaux3_IN 768 300
CANaux3_OUT 769 301
6.4.1 Allocation of individual identifiers
For greater system bus networks with many nodes it can be reasonable to set individual identifiers
for the CANaux1_IO ... CANaux3_IO process data objects via C2453/C2454, which are independent
of the node address set in C2350:
1. Set C2453/x to "1".
– (x = subcode of the corresponding process data object):

1 CAN addr sel1 0 CANaux1_IN/OUT
2 CAN addr sel2 0 CANaux2_IN/OUT
3 CAN addr sel3 0 CANaux3_IN/OUT
2. Set the value which, added to "384", makes the desired identifier in C2453/x.
