I program my own system and have a question which I hope someone can help with.
I have a relay operating a swimming pool valve. When I open this valve I want to set a flag high I. If the button gets pressed again I want to check to see if the valve is already open. Can anyone please help with on how to do this and what symbols to use.
Many thanks
