The apparatus control function is a program supervising operation of a set
of high-voltage apparatuses within a bay. Apparatuses in the form of
breakers, disconnectors, and earthing switches.

receive commands. Orders to operate an apparatus can come from the CC
(Control Centre), the station MMI, or the local back-up panel (via the I/

When operating from the local back-up panel, the apparatus control func-
tion can be bypassed. The back-up panel is hard wired to the apparatuses
for this purpose.
