Owning Palette: Signal Manipulation Express VIs
Requires: Base Development System
Groups digital data into a digital data array and groups digital waveforms into a digital waveform array.
LabVIEW treats ungrouped signals as individual groups.

Parameter | Description |

Number of signals | Specifies the number of signals you want to wire to the Express VI. Configure this option first. This number must match the number of signals you wire to Digital Data In. Otherwise, LabVIEW returns an error. |
Use incoming waveform names | Allows you to retain the original names of the waveforms you wire to Digital Data In. This checkbox contains a checkmark by default. Remove the checkmark from this checkbox to use the line and bus names you specify using the Rename button. |
Order of signals | Displays the sequential order of the digital signals. |
Plot Legend | Contains the lines and buses you configure in the configuration dialog box. Use this tree control to drag and drop lines into the order you want to view them in the output array. To put lines into groups, right-click a line and select Insert Bus and then drag other lines onto that bus. You cannot drag a line onto another line, a bus onto another bus, or a bus onto a line. |
Graph Preview | Displays a preview of the lines and buses based on the organization you specify in the configuration dialog box. |
Rename | Allows you to rename the line or bus you select in the Plot Legend tree control. You also can right-click a line or bus and select Rename from the shortcut menu or double-click a line or bus to type a new name. To rename lines or buses, you must remove the checkmark from the Use incoming waveform names checkbox. Otherwise, the incoming line names take precedence over the new names you specify. |
Insert Bus | Inserts a new bus above the line or bus you select in the Plot Legend tree control. You also can right-click a line or bus and select Insert Bus from the shortcut menu. |
Delete All Buses | Deletes all the buses from the Plot Legend tree control. To delete a single bus, right-click the bus and select Delete Bus from the shortcut menu. You can delete only buses, not lines. LabVIEW considers lines listed under deleted buses as ungrouped signals. |
Parameter | Description |
---|---|
Digital Data In | Specifies the input signals you want to organize into groups. |
error in | Describes error conditions that occur before this node runs. |
Parameter | Description |
---|---|
Digital Data Out | Returns a digital data array or a digital waveform array, depending on the data type of Digital Data In. |
error out | Contains error information. This output provides standard error out functionality. |
