Good morning WD,

Thanks for posting your question.

I ask all students to post their questions on the lesson the question is on. As you're not enrolled in any of our courses, please make use of our free forum at TheAutomationForums.com.

As far as PID, none of our courses cover the PID instruction as of yet as I haven't found a good process or simulator to use with a PID lesson. Once I do, I will add PID lessons to all my PLC/PAC courses.

Sincerely,

Shawn Tierney,
IInstructor at The Automation School
