Hello! I am trying to make a temperature PID controller and am having trouble getting my cartridge heater to respond. I am using the example provided by NI but have put in the components I am trying to control. I have a thermocouple indicating the temperature (wired to process variable temp) and a cartridge heater as my process variable. I have the cartridge heater wired to the output but cannot get the temperature to change. Can someone tell me if I have my VI wired correctly? Also, I need the state to be determined by the PID but am not sure how to set up my VI in this manner. I have included my VI. Any assistance would be appreciated. Thank you!

We can at least help in terms of the hardware. What type of signal does your cartridge heater expect? Which LabJack are you using and which output on that LabJack?
