Answer Posted / wael salah
maintenance override function is used for bypassing shutdown
processing so that it is not executed by safety logic during
partial maintenance such as specific input.Creating bypass
logic using a dedicated override allows the (HIS) to safely
perform maintenance override for SCS (system control station)
However Maintenance override can not executed from the HIS
unless this switch is in the permission status.
