9.7.1 PV Event
Description
The PV event is a function to output defined PV alarms, deviation alarms and others
which are related to the program.
If SP tracking is enabled when the program operation is completed, the registered PV
event together with the target setpoint will be tracked for local event and the event
function will be continued. If SP tracking is disabled, the PV event and the target setpoint
will be switched to the preset local event.
The PV event is set for each segment.
The PV event does not have a stand-by action and latch action.
The PV event action and hysteresis action are the same as the alarm action.
