*) Used with IEC 60870-105-103 communication protocol. The alarm screen
will show the latest if it's the biggest registered fault current, too. Not used
with Spabus, because Spabus masters usually don't like to have unpaired
On/Off events.
**) Used with SPA-bus protocol, because most SPA-bus masters do need an
off-event for each corresponding on-event.
