Short Name: Alarming.U32BitField.InvertMask
Requires: Base Development System
Class: Variable Properties
To Use: Create a property.
Gets or sets which bits of a shared variable alarm on high, 1, and which bits alarm on low, 0. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.
Enter the value 1 if you want that bit to alarm when low. In bitwise terminology, the Shared Variable Engine performs an XOR with the invert mask value to produce the alarm state. LabVIEW applies the invert 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 Invert option on the Alarming page of the Shared Variable Properties dialog box.
