[49] the oldest. A data log is made 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.
Warning word
3.
Alarm word
4.
Status word
5.
6. Control word
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 are available on the
display. This is useful, e.g. when carrying out service
after a trip. It is possible to monitor this parameter
via the serial communication port or via the display.
