Events and registers
The OV function generates events and registers from the status changes of start, trip and blocked. To
main event buffer is possible to select status “On” or “Off” messages. The OV function offers four
independent instances which events are segregated for each instance operation.
In the function is available 12 last registers where the triggering event of the function (start, trip or
blocked) is recorded with time stamp and process data values.
