Case Structure Voltage Initiation

[CINATAS]

I am trying to intitate a case structure with a digital input voltage. I know how to acquire the voltage, but I dont know how to convert the voltage into a boolean or numeric function to initiate the case structure. Attached is the code I have so far with a sub vi for the voltage. Any ideas? Thanks.

Follow your create digital channel with a DAQmx Read set for Digital>Single Channel>Single Sample>Boolean.

Hi,

you did not include the subvi. Remember that when you save a vi

the subvi are not saved in the same file unless it is a llb file (library).

If you want everything in one file try save with options=>developpement for example.

Please post the subvi or the complete library.

Anyway, what is the problem? You have a voltage and a case. What do you want to

do is the first question? When is the case true and when is it false?

When the voltage is lower than a certain value? Explain.

I want the case to be true when their is a 5 volt signal present.

I have added the read function. Is this correct?

Hi,

it looks ok at least for the part where you read the Digital Input and links it to the case.
