Bridge between input and output on VI Terminal

[IlMarione]

Hi, some one can explain how and why there is a bridge between my Char input and Output... I have tried to rebuild from zero the program but everytime i got the same result... Never seen things like this

Hi Marione,

input and output terminals might be placed on the wrong side, input to the right and output to the left…

To follow up on Gerd's excellent observation/suggestion:

• Look at your Front Panel.  Is "Testo_OUT" an Indicator? 
• Go to your Block Diagram.  Click on "Testo_OUT" and move it upwards a little so you can see a "unique" wire going to somplace on the "Pop Up" sub-VI.  Is it going to the right ("output") side of that VI?  What happens if you now drag "Testo_OUT" to the right, does the wire "jump" to come out of Pop Up on the right and into "Testo_OUT" on the left?
• Do a similar "untangling" on OPERAZIONI DA ESEGUIRE, which might be a control.  If so, drag it to the left of Pop Up.

We cannot diagnose the problem from such a picture, these wires might be overlapping or it could be one wire wired to two different terminals, We cannot tell anything.

Can you hover over the subVI with the mouse and bring up the context help with ctrl+h, then attach a screenshot of the context help window?

Who wrote the subVI?

It looks like this is what the OP did, and the image does actually have enough information in this case, because it has the terminal numbers.

Since we can see terminal 2 on the left and terminal 10 on the right, this tells us that they are indeed connected on the wrong side and the context help window overlaps the wires, because it tries to show inputs on the left and outputs on the right.

Yes, you are right. I think the context help should not be allowed to draw overlapping wires....
