Is there an easy and low cost PLC unit? Something around $100 or less?
The reason I ask is home use. When you install a PLC to, say, control pool equipment then it has to be nearly as easy to understand as programming a lawn sprinkler unit. Sure, we should all be able to program it but some day a house might be sold and then the new owners may not be so versed in that field. At least they should be able to find someone locally to program it.
