Why does program work only when highlight execution is on?

[hung]

I created the attached program to set a setpoint temperature and read actual temperatures. But why is it that it works perfectly fine only if the highlight execution lightbulb is on and does not work properly when the highlight execution is off (i.e. the VISA read does not read properly) ?
Thanks

When I've seen this happen, it usually turns out to be a timing issue.

With Hilight Execution turned on, the program executes much slower than it does when running normally.


Try putting some time delay between your steps, or Read/Write functions one at a time to see if that fixes your problem. If you find a problem spot, you can modify your code to compensate for the timing issue.
