Help Programming a Beckhoff PLC

[jnatzic 0]

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!

You should assign an %I address for any input variable which they've their values from input cards. After that you see the variable in the software and you can link them to the hardware. There is manual of TC3 in Beckhoff website which can help you
