Alarming:U32BitField:SelectMask Property
Short Name: Alarming.U32BitField.SelectMask
Installed With: Base Package
Class: Variable Properties
Gets or sets which bits LabVIEW uses to calculate the alarm for a shared variable. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.
LabVIEW uses bits that are 1 in the alarm calculation. Bits that are 0 do not cause an alarm, regardless of their value. In bitwise terminology, the Shared Variable Engine performs an AND with the select mask value to produce the alarm state. LabVIEW applies the select mask value to the scaled value after applying any relevant scaling masks.
 | Note You can enable alarming only for network-published shared variables. |
This property is similar to the Mask option on theAlarming page of the Shared Variable Properties dialog box.
