I know what some of the symbols are, normally open and closed switchs, coil symbol and so on, but the addresses have me a little confused.
I believe the "K" addresses are for Keep relays.
Are the "D" diagnostic bit address's??
Are the "Y"s physical outputs?
What are the "R" addresses?
what are the "F" addresses?
I just want to learn so I can trouble shoot problems better and so on.
thanks for you help
Jon
