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:
1. Digital input
2. Digital outputs (not monitored in this SW release)
3. Warning word
4. Alarm word
5. Status word
6. Control word
7. Extended status word
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.
