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

hex
PDOs
XCAN1_IO (cyclic process data)
XCAN1_IN

XCAN1_OUT

XCAN2_IO (event or time-controlled process data)
XCAN2_IN

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):
