How you end up developing a load shed system is up to you
This is a LOGO
There are some as cheap a 60 bucks if you shop around
I used these 20 years ago to do simple jobs that in the old days would have required a lot of relays and wires and devices that in todays money would cost maybe a thousand bucks in parts even before you factor the time to wire and test
So a logo is programmed in ladder or Boolean logic
You could use a pc and software linked by cables or key in the commands by hand from the face plate
Now you can probably use your phone blue tooth and who knows what else
It’s probably the most cost effective way to do this but you will need to learn the software
Original logo booklets shipped had no words just picto-graphs like a Lego block kit
There are other brands and Chinese knock offs if you want to research this
The advantage to build your own controls is once you know how it works
You can fix mod things on the spot
Some old stuff
I remember wiring these 800 series when they were state and of the art
They had very hard to use software and primitive processors
Then came the quantum with a pentium class processor.
Now you have unity
Distributed processing and data collection blaw blaw
Pieces of plastic Chinese shit
Out there somewhere right now an old 800 series is chugging along covered in filth in a place you would not to be just doing it thing running something
Gold plated contacts solidly built rack and parts
Show me a unity level automation package in 40 ( if I’m not dead that’s a stretch ) years still chugging a long….
Things change fast
