Block Diagram Errors....Tunnel: missing assignment to tunnel
This is a problem that is difficult to find. Basically what happens is that one of the wires that should be connected to the tunnel is not connected to the tunnel but is instead connected to its own tunnel. Kind of hard to expain, but click on the tunnel and move it. If this is the problem, there will be one underneath of it.
Solved: missing assignment to input tunnel
Re: missing assignment to input tunnel. JÞB. Knight of NI. 10-22-2014 09:30 AM - edited 10-22-2014 09:31 AM. Options. it is possible to have tunnels on top of each other. this gets really ugly since the tunnels look wired but are not. there is a VI Analizer test for overlapping (or hidden) objects that would catch this.
why my VI shows tunnel missing assignment?
Hello, I need to control two relays, if one open, then the other closed. This is decided by the numberic input is higher than 47 or not. Then, i hope if click stop button, all the setting to the two relays can reset to initial status. However, my VI shows tunnel missing assignment. Does anyone kno...
Product Documentation
To correct this error, move to the case (s) that contain (s) the unwired output tunnel and wire an output to the tunnel. You also can configure the tunnels on a structure to wire the input and output tunnels automatically in unwired cases. When the output is properly wired in all cases, the output tunnel is a solid color.

tunnel corresponds to the array containing all entries under the ith index of the first array dimension. Enabling and Disabling Auto Indexing To enable or disable Auto Indexing, right-click on the tunnel that you want to change and select "Enable Indexing" or "Disable Indexing" as shown in Figures 4 and 5. Figure 4 Figure 5
Undirected Tunnel Error With Stacked Sequence Structure
Solution. There are a few different steps you can try to fix this error: If a source is connected on both sides of the structure or no source is connected, the tunnel cannot decide the direction of dataflow. Verify that every case in your stacked sequence structure is fully wired, and that a source is never connected on both side of the structure.
Set Tunnel to default value by scripting
Here's a versions with a few modifications : - fixed the undo. - do nothing if launched from panel. - if selection is a case structure, take all tunnels and enable "use default..." if not already enabled. - if zero tunnel were effectively modified, fail the undo. - if at least one tunnel was effectively modified, force recompile the VI to make ...
Auto-Indexing Tunnels with For Loops and While Loops in LabVIEW
Additionally, when you auto-index an array output tunnel, the output array receives a new element from every iteration of the loop. Enable or Disable Auto-Indexing. Input Terminals: To switch between auto-indexing and non-indexing tunnels for an input terminal, right-click a tunnel and select Enable Indexing or Disable Indexing. Output Terminals:

Concatenating Tunnel Mode Wire Broken When VI Is Saved to Previous ...
The Concatenating Tunnel Mode functionality for strings was added starting in LabVIEW 2021. Thus, when saving the VI from LabVIEW 2021 to LabVIEW 2020, it is an expected behaviour. I created a program using the Concatenating Tunnel Mode of the case structure in LabVIEW 2021. Then I saved the program as LabVIEW 2020 version by Saving for a ...

Re: missing assignment to tunnel. Nirmal_Sharma. Member. 12-29-2003 11:19 PM. Options. Hi, Click the case selector, move it down, you will see a tunnel which is not used. Delete this tunnel if not to be used. Tunnel could be used for passing your values to parameter such as Min Speed & Max speed.
Avoiding Wiring Unwired Output Tunnels on Case Structures
Right-click the output tunnel and select Use Default If Unwired from the shortcut menu to use the default value for the tunnel data type for all unwired tunnels. Configure the tunnels on a structure to wire the input and output tunnels automatically in unwired cases, which is the recommended best practice. Note You can define a different data ...

Create —LabVIEW automatically wires the tunnels in any new cases you create. Existing cases remain unwired. The tunnel selector cursor appears. Note LabVIEW disables these options if there are no tunnels to which you can link. Click the input tunnel you want to associate with, or link to, the output tunnel. White triangle glyphs appear on the ...

Solution. This can be solved in different ways, depending on the cause: Look for an undefined tunnel on a loop structure. This is represented as a black tunnel on the border of a While or For Loop. Delete the terminal to remove the broken arrow. Force a recompile of the VI (Press Ctrl+Shift and left-click the Run arrow from LabVIEW).
