operate from local, station and remote level without any priority. When the external
panel switch is in Off position, the PSTO output shows the actual state of the
switch that is, 0. In this case, it is not possible to control anything. The LocSta
command value is forced to
FALSE
if
AllPSTOValid
is set to
No priority
.
If the setting
RemoteIncStation
is set to
Yes
and the LR-switch position is in
Remote state, the PSTO output is set to 2 (Station or Remote), that is, it is
permitted to operate from both station and remote level without any priority.
If the LR-switch position is in Remote state, and
AllPSTOValid
is set to
Priority
and
RemoteIncStation
is set to
No
, the switching between station and remote level
control is done through the command LocSta. The command is accessible only
through the IEC 61850 Edition 2 protocol.
