4.4 Identifiers of the process data objects
The identifiers for the XCAN1_IO ... XCAN3_IO process data objects are generated by the so−called
basic identifier and the node address set in C2350:
Identifier + basic identifier ) node address
Basic identifiers
dec hex
PDOs XCAN1_IO (cyclic process data)
XCAN1_IN 512 200
XCAN1_OUT 384 180
XCAN2_IO (event− or time−controlled process data)
XCAN2_IN 640 280
XCAN2_OUT 641 281
XCAN3_IO (event− or time−controlled process data)
XCAN3_IN 768 300
XCAN3_OUT 769 301
4.4.1 Allocation of individual identifiers
For greater system bus networks with many nodes it can be reasonable to set individual identifiers
for the XCAN1_IO ... XCAN3_IO process data objects via C2353/C2354, which are independent of
the node address set in C2350:
1. Set C2353/x to "1".
– (x = subcode of the corresponding process data object):

2. Set the value which added to "384" makes the desired identifier in C2354/x.
