Ab ml1400 pid

[mark.hines]

Hi,

I know it has probably been before posted before, but where can I get a sample program for a ML1400 or similar showing a working simple PID loop..???
And maybe a little description.
Ive read most all that I can find on PID's and Im still not clear on what to do and I have an application where I think I need to use one.
Thanks,

Here is a PID example for RSLogix500. Rungs 19 and 20 are scaling the values for the PID loop Process Variable at memory location N9:51, and the Control Variable at N9:52.
