Short Name: Scaling.InvertMask

Requires: Base Development System

Class: Variable Properties

To Use: Create a property.

Gets or sets the bits that the Shared Variable Engine inverts before storing them in a shared variable. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.

The Shared Variable Engine inverts bits in the mask with value 1 but does not invert bits with value 0. The default invert mask is 0, indicating that the Shared Variable Engine inverts none of the bits. In bitwise logic terminology, the Shared Variable Engine performs an XOR with this value to produce the scaled value.

You can use this property for shared variables with a Data Type of U32BitField.

This property is similar to the Scaling Invert Mask option on the Scaling page of the Shared Variable Properties dialog box.
