Short Name: Alarming.Hi.Deadband

Requires: Base Development System

Class: Variable Properties

To Use: Create a property.

Gets or sets the HI alarm deadband as a percentage of the full scale range. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.

A shared variable does not return to a normal state until it has left the alarm condition set by the value of the Alarming:Hi:Level property by at least the value of the deadband. If you set the deadband too high, the shared variable value might not clear the alarm.

Note  You can enable alarming only for network-published shared variables.

This property is similar to the Deadband/Time option on the Alarming page of the Shared Variable Properties dialog box.
