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.
