Case structure wiring

Go to solution

Hi LabVIEW Folks,


I'm so interested to learn a quick wiring tip for case structure without having to wire manually for every single state. I know there is an option "use as default value" but I'm interested in actually wiring because I'd need this for shift register where values are different than default.


It is really frustrating to wire a new data value manually through every state in case structure.


For more resolution, I've attached VI.


Let me know if I'm not clear with my question. Thanks!


I know this forum always rocks. Appreciate all helps so far.

Hi Jatin,


since several LabVIEW versions you can right-click an output tunnel to make it a "linked tunnel"…

Best regards,

Hi Jatin,


i feel very comfortable using Functional Global Variables


not only for case structure but also for the whole project 🙂

Linked Tunnels are what you are looking for.  They have been around since LabVIEW 8.6!


Just right-click on the output tunnel and there are a couple of options for linking the output tunnel to the input tunnel.  One of those options is to go ahead and wire all of the unwired cases for you.

There are only two ways to tell somebody thanks: Kudos and Marked Solutions
