ML 1400 Temp Control

[Bblank 0]

I have a Micro Logix 1400 L32BXBA with a 1762-OF4, and a 1762-IT4, wondering if someone has a simple project using PID, measuring with a K type t/c and controlling an output to a scr with 4-20ma

All you really need is a PID instruction. Input tied directly to the process variable, output tied directly to the control variable. Set up the scaling, etc. in the PID instruction block.
