Identifiers of the process data objects

The identifiers for the CAN1_IO ... CAN3_IO process data objects are generated by the so−called
basic identifier and the node address set in C0350:

Identifier + basic identifier ) node address

Allocation of individual identifiers

For greater system bus networks with many nodes it may be reasonable to set individual identifiers
for the CAN1_IO ... CAN3_IO process data objects via C0353/C0354, which are independent of the
node address set in C0350:

1. Set C0353/x to "1".

– (x = subcode of the corresponding process data object):

2. Set the value which added to "384" makes the desired identifier in C0354/x.
