Main menu/
Diagnostics/Internal events
. The message includes the date, time, description and
signal state for the fault. The internal event list is not updated dynamically. The list is

to be permanent, the IED stays in internal fault mode. The IED continues to perform
internal tests during the fault situation.
When a fault appears, the fault indication message is to be recorded and stated when
