Range:
0 - 100 N/A

trigger event which are to be retained in the log.
See also par. 15-12 and par. 15-13.
15-2* Historic Log
"
View up to 50 logged data items via the array
parameters in this parameter group. For all
parameters in the group, [0] is the most recent
data and [49] the oldest data. Data is logged every
time an event occurs (not to be confused with SLC
events). Events in this context are defined as a
change in one of the following areas:
Digital input
1.
Digital outputs (not monitored in this SW release)
2.
3. Warning word
4. Alarm word
Status word
5.
Control word
6.
Extended status word
7.
Events are logged with value, and time stamp
in msec. The time interval between two events
depends on how often events occur (maximum once
every scan time). Data logging is continuous but if
an alarm occurs, the log is saved and the values can
be viewed on the display. This feature is useful, for
example when carrying out service following a trip.
View the historic log contained in this parameter via
the serial communication port or via the display.
