Forcing VIs
Owning Palette: NI Scan Engine VIs
Requires: Base Package (Windows, VxWorks, ETS). This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Forcing VIs to force and unforce I/O variables programmatically.
The VIs on this palette can return general LabVIEW error codes.
| Palette Object | Description |
|---|---|
| Clear Variable Forcing | Unforces all currently forced I/O variables and I/O aliases on the target. |
| Disable Variable Forcing | Disables forcing for I/O variables and I/O aliases on the target. Unless you clear forcing, the previous forced values return when you re-enable forcing. |
| Enable Variable Forcing | Enables forcing for I/O variables and I/O aliases on the target. |
| Force Variable | Forces an I/O variable or I/O alias to assume forced value until you disable forcing, reboot the target, or force the variable to assume a new forced value. |
| Unforce Variable | Discontinues forcing on an I/O variable or I/O alias and returns control of the I/O value to the NI Scan Engine. |
