Last week I asked about the future of control in 10 years.
We had some really good back and fourths and a couple people brought up that a PAC is the future.

My immediate response it a PAC is just marketing jargon to charge more for the normal continuation of PLC development.

Are many of the controllers that we are calling PAC’s beefier than PLC’s?
Can they have more I/O?
Will they have more processor?


That’s also the normal development and continuation of PLC’s.

I remember the exact moment after much reading that I came to this conclusion –
It was a late on a Friday Night.
Beth was asleep in the AirBnB in Loudoun County, VA

After reading everything I could find
– I quietly said to myself –
This is just marketing jargon for PLC’s.

So my question to youΒ #automationΒ community –

Is the difference between a PLC and a PAC marketing jargon or just mostly marketing jargon?

Of note…

There was a surprisingly large variation in opinions. Many people agreed with my assertion that it was marketing jargon. Some were asserting that there was a major difference beyond just a normal design and upgrade cycles of “legacy PLC’s”.
