The function generates general time stamped ON/OFF events to the common event buffer from each of
the two (2) output signals as well as several operational event signals. The time stamp resolution is 1
ms. The function also provides a resettable cumulative counter for OPEN, CLOSE, OPEN FAILED, and
CLOSE FAILED events.
The following figure presents a simplified function block diagram of the object control and monitoring
function.
