2.1.5 Switching on the power supply

2-28
Note
Observe also the instructions in the manual for your con-
troller with Interbus interface.
When the controller with Interbus module is switched on, it
automatically carries out a comparison between the NOMIN-
AL and ACTUAL configurations. It is important for this config-
uration run that:
– The configuration specifications are complete and correct.
– The fieldbus stations are supplied with voltage so they
can be detected when the ACTUAL configuration is ascer-
tained.
Therefore, switch on the power supply for all the fieldbus
stations simultaneously, e.g. via a central switch. Or switch on
the power supply in the following sequence:
1. First switch on the power supply for all fieldbus stations.
2. Then switch on the power supply for the controller.
