Hi. Let me explain the program: - Main.vi is the main vi. Inside is a loop with sub vi's in it. After doing the necessery the settings, it calls a sub vi ->> Problem.vi - Problem.vi is where the actual temperature measurement is done in a loop. There is a digital display with the current temperature measurement, so that it displays the temperature on the front panel each loop cycle. My question is: - How do I display the current temperature measurement in Main.vi ? If I use a global variable, it only dislays the last temperature value. Meaning, only after finishing Problem.vi, would the temperature value in Main.vi change Thanks in advance!!!!!

LabVIEW

Global Variable

User events are documented with the Event Structure. If you have the Base version of LabVIEW, the Event Structure is not available. I have attached a small example of how to use user events. Both VIs in the example use the Event Structure.
