4.4 Process data object identifiers
The identifiers for the process data objects XCAN1_IO ... XCAN3_IO are composed of the so-called
basic identifier and the node address set in C2350:
Identifier
=
Basic identifier
+
node address
Basic identifier
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 Assignment of individual identifiers
For bigger system bus networks with many participants it might be useful to set individual identifiers
for the process data objects XCAN1_IO ... XCAN3_IO via C2353/C2354 that are independent of the
node address set in C2350:
1. Set C2353/x to “1”
(x = subcode of the corresponding process data object):

• Save changes with C0003 = 1
• Changes will only become
effective after a reset node!
1 XCAN addr sel1 0 XCAN1_IN/OUT
2 XCAN addr sel2 0 XCAN2_IN/OUT
3 XCAN addr sel3 0 XCAN3_IN/OUT
2. Set the value that results in the desired identifier when adding “384” in C2354/x
(x = subcode of the corresponding process data object):
