So, again, I find myself asking a dumb question. 
I am trying to figure out how to write logic to use a 1734-IT2I, with a type J thermo-couple.
I am not sure if I should try and figure out how to use a PID, or if there is some other function I should be using, something like scaling.
In the past, with RSLogix 500, I would have tried using the scaling, but it is not available in ladder logic with Studio.
I want to reference the first channel to monitor a temperature, and use it to control an output.
And for the record, I am using Studio and a CompactLogix controller. The module is in slot 4 of a 1734-AENT, and the program sees it, and says it is viable.
But for the life of me, I cannot figure out how to see it in the ladder logic.
This may really sound dumb to you engineers, but I am trying to learn this on my own.
I have attended a couple of Allen-Bradley classes, but they never touched on this.
Any help really would be appreciated.
