4.1.1 Switching on the operating voltages
No te
Please observe also the switching−on instructions in the
manual for your controller.
When the controller is switched on, it automatically carries
out a comparison between the NOMINAL and the ACTUAL
configurations. For this configuration run it is important that:
the specifications for the field bus configuration are
complete and correct.
the power supplies for the programmable logic controller
and for the field bus slaves are switched on either simul
taneously or in the sequence indicated below.
Observe the following points before switching on the power
supply:
Common supply Common power supply for the control system and all field
bus slaves via a central power unit or a central switch.
Separate supply If the control system and the field bus slaves have separate
power supplies, the devices must be switched on in the
following sequence:
1. the operating voltage supply for all field bus slaves
2. the operating voltage supply for the controller.
