Switching a Power Supply ON/OFF through LabVIEW/VISA

Hello,

I am looking at controlling an Agilent Power Supply through LabVIEW. I have written a standalone VISA code which allows me to do this (find the attached image). This code allows me to make the power supply output a certain voltage and the return string verifies what voltage the supply outputs.

However, I am now looking at getting this power supply to switch off (i.e. output 0 volts) when any of the 5 temperatures I'm reading exceeds a certain value. Could someone tell me how I can go about adding this new piece of information in the code I have or a basic structure of how it's done?

Thanks
