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.<br />
<br />
<!--begin parent=lvdsc:configure_bit_array_alarms.html-->LabVIEW uses bits that are <code>1</code> in the alarm calculation. Bits that are <code>0</code> 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.<!--end parent=lvdsc:configure_bit_array_alarms.html--><br />
