5.4 Process data object identifiers
The identifiers for the process data objects FIF_CAN1_IO ... FIF_CAN3_IO are composed of 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 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 FIF_CAN1_IO ... FIF_CAN3_IO via C2453/C2454 that are independent
of the node address set in C2350:
1. Set C2453/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 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 that results in the desired identifier when adding “384” in C2454/x
