Events and registers
The circuit breaker wear function (abbreviated "CBW" in event block names) generates events and
registers from the status changes in Triggered, Alarm 1 and Alarm 2 signals as well as in internal pick-
up comparators. The user can select which event messages are stored in the main event buffer: ON,
OFF, or both.
The events triggered by the function are recorded with a time stamp and with process data values.

The function registers its operation into the last twelve (12) time-stamped registers. The register of the
function records the ON event process data. The table below presents the structure of the function's
