Gets or sets the deadband for logging a shared variable in the Citadel historical database. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.

Use this option to improve the performance of an application by limiting unnecessary datalogging. LabVIEW logs a new shared variable value only if that value differs by at least the deadband value from the value previously logged. The default value is 0%, which logs each new value for the shared variable. This option is available only for shared variables with a Data Type of Double or Single.

Note You can enable logging only for network-published shared variables.

This property is similar to the Value Deadband option on the Logging page of the Shared Variable Properties dialog box.
