Event codes

Special codes have been determined to represent certain events, such as start and
tripping of protection stages and different states of output signals.
Events E1...E51 are stored in the event register of the relay. The maximum capacity
of the register is 60 events. Under normal conditions the register is empty.
The contents of the register can be read using the L command, five events at a time.
Using the L command erases the previously read events from the register, with the
exception of events E50 and E51 which have to be reset using the C command.
Should a fault occur, for example in data communication, these events can be re-read
using the B command. If needed, the B command can also be repeated.
