Could anyone explain the difference between AB's SLC 500 and PLC 5,
there is simply too much of info to be browsing through on their site; if anyone could just put the main difference in lame terms--it would be great.

I have a small homework problem, I'm trying to decide which one is best to control lead/lag pump design?

MUCH Appreciated!

Hello atc9443,

There are a couple of minor diferences in instruction set. There are big diferences in I/O addressing. I understand that some PLC5 CPU's have direct DeviceNet interface. With SLC you have to use a scanner.
Programming software is different , but very similar.
PLC5 is older and very expensive.

Hope this helps
