Events and registers
The object control and monitoring function (abbreviated "OBJ" in event block names) generates events
and registers from the status changes in monitored signals as well as control command fails and
operations. The user can select which event messages are stored in the main event buffer: ON, OFF, or
both.
The function registers its operation into the last twelve (12) time-stamped registers. The events triggered
by the function are recorded with a time stamp and with process data values.
