I am a second year EET student and have a small final project that simulates a coin operated car wash.
As it is our last project for the intro to PLCs we are required to use subroutines or sequencers.
The car wash has 4 different cycle choices:
Wash only-1 coin
Pre-rinse & Wash-2 coins
Wash & Hot Wax-3 coins
Pre-rinse & Wash & Hot Wax-4coins
Pre-rinse:
Water-3sec
Wash:
Water&Soap-4sec
Water&Soap&Brushes-12sec
Water-4sec
Blower-5sec
Hot Wax:
Wax-3sec(before blower)
I seem to have gotten it to operate fairly well but in my final SBR7 where I am adding a shut down program is where I have gotten confused.
Any help or advice with this would be great. I am not really looking for a prefect answer to my problem just a suggestion.
