Boolean value turns to false after leaving while loop

[lorc34]

Hi,

I have a labview program which checks the time and if the time is between 7 AM and 5 PM, it outputs a true value from an 'and' object. 

This then goes into an if loop TRUE which runs a subVI.

The subVI then runs for 7 hours and turns off.

How I currently have it working is that I click 'run continuously' on the 'master' VI.

However I would like to not have to do run continuously but rather have the time checker in a while loop.

The problem is, when I try to bring the boolean value out of the while loop, it suddenly turns from true to false?

Is there a way around this?

I have attached 3 VIs, the labview master file and its subVI 'labview automated file' which work fine with 'run continuously', plus my attempt at making the master file use a while loop.

You said "LabVIEW automated file" is a subVI. Get whatever you don't want to run continuously out of the while loop. Based on what you are describing, a state machine would be a good option or maybe not. 

When you said "I try to bring the boolean value out of the while loop", what boolean are you referring to ?  what value are you trying to bring out?

You only attached two files. "Run continuously" is a debugging tool, not  a way to do any regular run. Most of your subVI code seems very amateurish, with oversized diagrams and right-to-left wiring. Do you know who wrote it?

You talk about a Boolean that turns false. Where is it?

All you probably need is the subVi. Turn it into a simple state machine that checks the clock and does whatever needs to be done according to state (something, nothing, etc.).
