5.4 Identifiers of the process data objects
The identifiers for the FIF_CAN1_IO ... FIF_CAN3_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 identifier
dec hex
PDOs FIF_CAN1_IO (cyclic process data)
FIF−CAN1_IN 512 200
FIF−CAN1_OUT 384 180
FIF_CAN2_IO (event− or time−controlled process data)
FIF−CAN2_IN 640 280
FIF−CAN2_OUT 641 281
FIF_CAN3_IO (event− or time−controlled process data)
FIF−CAN3_IN 768 300
FIF−CAN3_OUT 769 301
5.4.1 Allocation of individual identifiers
For greater system bus networks with many nodes it can be reasonable to set individual identifiers
for the process data objects FIF_CAN1_IO ... FIF_CAN3_IO 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 FIF−CAN1_IN/OUT
2 CAN addr sel2 0 FIF−CAN2_IN/OUT
3 CAN addr sel3 0 FIF−CAN3_IN/OUT
2. Set the value which, added to "384", makes the desired identifier in C2453/x.
