VLACTION - APMonitor Option

 Type: Integer, Input
 Default Value: 0
 Description: Validity Limit Action

VLACTION is the validity limit action when VDVL is exceeded. The change in measured values is recorded at every cycle of the application and compared to the VDVL limit. Validity limits are placed to catch instrument errors that may otherwise create bad inputs to the application. If a delta validity limit is exceeded, the action is to either freeze the measured value at the last good value (VLACTION=0) or change the measured value by a maximum of VDVL in the direction of the bad measurement (VLACTION=1).
