OFF means that no operator place is allocated.
LOCAL means that the IED is controlled locally via the HMI or local panel (PC or
similar).
REMOTE means that the IED is controlled from a higher level location such as the
substation control centre (MICROSCADA) or network control centre (SCADA).
Settings can still be done locally but all control functions are lifted to the next level
in the control hierarchy.
Parameter setting can always be done at all levels. It is the capability to execute control
functions that is moved from place to place.
