  1. I am trying to open a valve with a 24v digital output terminal (EL2828) on my Beckhoff CX9020.  I got the code working and the diagnostic LED lights up on the terminal when I want it to.  The problem I have is that there is no voltage coming out of the terminal and going to the valve.  Any ideas on what the problem could be?
  2. Help Programming a Beckhoff PLC

    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!
