Events are logged with value and time stamp in ms. The time interval between 2 events depends on how often events occur (maxi-
mum 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 parame-
ter via the serial communication port or via the display.
