5.4 Identifiers of the process data objects

The identifiers for the FIF_CAN1_IO ... FIF_CAN3_IO process data objects are generated by 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 Allocation of individual identifiers

For greater system bus networks with many nodes it can be reasonable to set individual identifiers

for the process data objects FIF_CAN1_IO ... FIF_CAN3_IO via C2453/C2454, which 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 are only valid after

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 which, added to "384", makes the desired identifier in C2453/x.
