2.2.1 Switching on the power supply
Please note
Observe here also the instructions in the manual for your
controller with DeviceNet module.
When a controller with DeviceNet module is switched on, it
automatically carries out a comparison between the
NOMINAL and the ACTUAL configurations. It is important for
this configuration run that:
 the configuration specifications are complete and
correct
 the bus interface is supplied with power
 the field bus slaves are supplied with power, in order that
they can be recognised when the ACTUAL configuration is
ascertained.
Therefore after switching on the power supply for the bus
interface, switch on the power supply for all the field bus
slaves simultaneously, e.g. by
means of a central switch.
Or switch on the power supply in the following sequence:
1. the power supply for the bus interface
2. the power supply for all the field bus slaves
3. the power supply for the controller.
