Events are logged with value, and time stamp in ms. The
time interval between 2 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.
