| 4F483C7E | Network:Project Binding | Indicates if the variable is bound to a project item or a URL. If TRUE, the variable is bound to a project item. If FALSE, the variable is bound to a URL. | Read/Write | No |
| 4F483C7F | Network:On Scan | Read/Write | No | |
| 4F483C80 | Update Deadband:Enabled | Enables the update deadband for a shared variable. If TRUE, LabVIEW updates the value of a shared variable only if the percentage difference between the new value and the previous value equals or exceeds the deadband. The default is FALSE. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module. | Read/Write | No |
| 4F483C81 | Update Deadband:Source | Gets or sets the deadband for updating the value of a shared variable when the value for the binding source changes. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module. | Read/Write | No |
| 4F483C82 | Update Deadband:User | Gets or sets the deadband for updating the value of a shared variable when a user writes data to the variable. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module. | Read/Write | No |
| 4F483C83 | Data Type (Variant) | Sets the data type of the variable to the data type you wire to this property. | Read/Write | No |
| 4F483C84 | Single-Process:Enable Timestamp | If TRUE, a timestamp value is recorded each time the single-process shared variable reads data. (Real-Time, Windows) To view timestamp information and add a timestamp output to the Shared Variable node, right-click the Shared Variable node and select Show Timestamp from the shortcut menu. If this property is FALSE, the timestamp output is hidden. You can use this property only with single-process shared variables. The default value is FALSE. | Read/Write | No |
