how to give case selection in commands for serial port write

[perumpadapu]

I am atatching a VI . The help needed explained there. I f anyone can hel me please reply

[Ranjeet_Singh]

Its too confusing.Let me know what. One more thing where you want to put ?

What are the different condition you want to test ? You want one output from two different variable or you have two different input and one output ?

[perumpadapu]

yes I have two different inputs at two diffrent conditions. when the condition changes from - to + value, with the same serial write I have to write the command in the program

[perumpadapu]

in that VI I have shown most of the requirements

[Ranjeet_Singh]

Try this ?

Hope this is only what you are looking for.

[Ranjeet_Singh]

Got it. Give me 5 min 

[Ranjeet_Singh]

Is is possible that both the inputs i.e. y & y1 can be 0.01 & -0.01  ?

[Ranjeet_Singh]

If at a time only one condition is TRUE then you can go with this.

This concatenation will work here

Hi perumpadapu,

why are you discussing the very same topic in (at least) two different threads? Why not keep everything in one place?

[Ranjeet_Singh]

Because of this I already posted my same VI in both the places
