Switching on the operating voltage
PLEASE NOTE
Observe also the switching on instructions in
the manual for the PLC/PC.
When the control system is switched on, the
controller compares the nominal and the actual
configuration. For the configuration run it is
important that:
•
the specifications on configuration are as
complete as possible and are correct;
•
the power supply to the controller and to
the connected slaves is switched on either
simultaneously or in the correct sequence.
Please observe the following points regarding
switching on the power supply:
•
Common supply: If the control system and
the field bus slaves have a common power
supply, they should be switched on via a
common power supply unit or common
central switch.
•
Separate supply: If the control system and
the field bus slaves have separate power
supplies, they should be switched on in the
following sequence:
1. operating voltage for the field bus slaves
2. operating voltage for the control system
