Number of similar events

description
Events subject to security breach "v" are broken down with an addi-
tional coding (3):
0 = One of the 10 most recent events or faults
1 = The longest event from one of the last 10 days during which an
event appeared
2 = One of the 5 longest events of the last 365 days
3 = The most recent event from one of the last 10 days during
which an event appeared
4 = The most serious event from one of the last 10 days during
which an event appeared
5 = The 5 most serious events of the last 365 days
6 = The first event or first fault after the most recent calibration
7 = An active event or a continuing fault
0 = For this event, it is not necessary to save "number of similar
events".
1 = One event of this type appeared on this day.
2 = Two events of this type appeared on this day, but only one was
saved.
n = "n" events of this type appeared on this day, but only one was
saved.
