When the forced positions of the CB and the
Isolators are used (during commissioning test)
Function Key 1 is activated.
In 'Normal' mode it is high on key press and in
'Toggle' mode remains high/low on single key
press
Function Key 10 is activated.
In 'Normal' mode it is high on key press and in
'Toggle' mode remains high/low on single key
press
General Alarm
The IED is not subscribed to a publishing IED in
the current scheme
GOOSE Output 1
Allows user to control a binary signal which can be
mapped via SCADA protocol output to other
devices
