I have a very simple problem that I need help with. I have some programming experience but I am brand new to PLCs and structured text. I am using TwinCat 3 to program a Beckhoff CX9020. My goal is to read the temperature from my thermocouple and open or close a valve based on the temperature. I have successfully connected the PLC to the TwinCat software and I am able to see the value of the thermocouple increase and decrease when I touch it with my fingers. I need to link that value to a variable in my code so I can have the valve act on it. I don't know how to properly address the inputs and outputs. Thank you!
