5 Configuration (FIF interface)
With an appropriate function module (e.g. system bus CAN-I/O), you can use the FIFinterface of the
Drive PLC as an additional system bus interface.
Note!
If the fieldbus module plugged on the FIF interface and the integrated system bus interface are
connected to the same system bus network, please ensure that you have set different CAN
addresses and different identifiers for the interfaces!
Tip!
Changes in the CAN baud rate, the CAN addresses and the PDO identifiers are only accepted after
a reset node.
A reset node can be initiated by
• Afreshpower-on
• A reset node command through an NMT command (^ 2-5)
• A reset node via C0358 (^ 5-7)
5.1 CAN baud rate
All participants must use the same baud rate for data transmission to enable communication via the
system bus.
• The baud rate is configured via code C2451:

C2451 CAN1 baud rate 0 0 500 kbit/s

• Save changes with C0003 = 1
• Changes will only become
effective after a reset node!
5.2 CAN boot-up
Unless a higher-level host system controls the system bus initialisation and the status change from
pre-operational
to
operational
, you can select a PLC or a drive controller as a “quasi” master to fulfil
this task.
• Configuration is made via code C2452:
