Missing part of the picture.  The diagram disable structure has an enabled pane as well.

Sooo...

If the diagram disable structure was added and the enabled pane was left as its default, the answer will be zero (A).

However, if it were to be wired, the answer would depend on how it was wired.

Hi BPerlman.  I didn't post the Enable pane as I felt that there was enough information shown to answer the question.

HINT:  This is Disable Diagram Structure question with a second CLAD concept twist.

[BPerlman]

Ohhh....I zoomed in and now I see it.  That little bit of whiteness....

OK, I say A.

[mini09]

A, that was tricky.. Initially my thought was 7 later switched to 0.

[crossrulz]

A.  The Use Default If Unwired is the main key there.

B.  The second adding function is what is disabeld

Very popular this post.  I am curious why there are loads more views compared to normal.  Any thoughts?

Great to see some new participants....welcome.

There's a link to The Daily CLAD in the latest NI News.  I never knew it existed before.

[BPerlman]

Ditto.  I just saw it in NI News.

[SercoSteveB]

Ooooo The Daily CLAD makes the NI Press, I will have a look for that.  Cheers.

[SercoSteveB]

I can't find it anywhere.  Can someone send me a link please?

Where to get that 'disabled' block? Is it a case structure?

[mini09]

Go to functions pallete ->programming-> Structures -> Diagram disabled structure (or) press Ctrl+ Space and type the Diagram disabled structure.

Answer: A.  Nice one somashekhar_m, LordNobady, BPerlman, gnshmrthy, crossrulz, crossrulz & MrStevenUND

Steve,

  Is it an assumption that there is no connection in the enable pane?

   If there is some connection in the enable pane, the result will depend on those connections.

The output tunnel shows that nothing is in the Enabled case here.  If there was something wired, the output tunnel would be completely filled in.
