Gets or sets the bits the Shared Variable Engine uses for a shared variable. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.

The Shared Variable Engine stores bits in the mask with value 1 in the shared variable. The Shared Variable Engine sets bits in the mask with value 0 to 0, regardless of the value received from the server. In bitwise logic terminology, the Shared Variable Engine performs an AND 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 Select Mask option on the Scaling page of the Shared Variable Properties dialog box.
