Owning Palette: Model Interface VIs
Requires: Model Interface Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Signals VIs to read values from signals in a model as the model executes.
Programming Patterns: Probing Signal Values at Run Time
| Palette Object | Description |
|---|---|
| Close Signal Interface | Closes a reference to model signals that you opened with the Create Signal Interface VI. |
| Create Signal Interface | Creates a reference through which you read from the signals in a model. Use the reference this VI creates to set a list of signals to read, then read their values from background-priority code as the model executes. |
| Format Raw Signal Values | Returns an unflattened version of the model signal values in the flattened Data Array in. This VI is useful if you want to read raw signal values quickly while the model executes and later reformat them offline for visualization. |
| Get Probed Signal Values | Returns the values of signals in a model that you previously chose to probe. Each time this VI executes, it returns signal values from a particular time step, unless the VI times out.
Call the Set Signals to Probe VI before this VI to configure the list of signals to probe. |
| Set Signals to Probe | Sets which signals in a model you want to probe. After you set the signal list, the Get Probed Signal Values VI returns values for those signals as the model executes. |
