in this context are defined as a change in 1 of the
following areas:
•
Digital inputs.
•
Digital outputs.
•
Warning word.
•
Alarm word.
•
Status word.
•

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
