how to have three different output according to different input range

[Steve_Lee]

Hello, everyone

I have such a situation. There are three output values -5, 0, 5 which are chosen according to the range of input value. If input value is less 3, output -5; if input value is between 3 and 4, output 0; if input value is greater than 4, output 5. How can I make it happen in labview? Thank you all.

Hi, Li:

   The attached VI should do the trick

Thank you, Steelston.

Can you attach a picture of the diagram please? I'm using labview 8.0 and couldn't read your version 8.2 properly.

Thanks.

This should work

Here's a version 8.0

Did you know that a single case statement can have ranges? For example, if you have an integer wired to the selector, you can type '..1' as the case value and it will handle everything less than or equal to 1. You can enter 5.. for values equal to or greater than 5. You can enter comma separated values such as '3,4'. If you use this, you should really use integer comparisons as floating point comparisons and computers can lead to unexpected results.

Ah yes,

    Well, that's the old analog designer in me coming out. 🙂 I just went for the obvious.  But your technique is very cool.  I shall definitely put that in my repertoire.  Thanks!!
