15-2* Historic Log
View up to 50 logged data items via the array pa-
rameters in this parameter group. For all param-
eters 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:
1. Digital input
2. Digital outputs (not monitored in this SW
release)
3. Warning word
4. Alarm word
5. Status word

Events are logged with value, and time stamp in
msec. The time interval between two events de-
pends 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 use-
ful, for example when carrying out service follow-
ing a trip. View the historic log contained in this
parameter via the serial communication port or
via the display.
