Automation Q & A from the Morning Show dated 03/16/23:

There’s no question that Digi-Key has contributed to the industry with its many high quality (and completely free) technical articles. But the question today is if they got the difference between PLCs and PACs right in their recent article, a question I share my thoughts on in this edition of Automation Q&A.

NOTE: You’ll find the article mentioned in this episode here.

NOTE: If you need to learn how to program, use, and troubleshoot Allen-Bradley PACs or Siemens S7 PLCs, check out my courses at The Automation School. They come with support and never expire.

Until next time, Peace ✌️
