> 1: Draw a ladder diagram using the schematic editor in Eagle. I love that kind of (mis) use. Seems like an irresistible project should I ever have more time than work at hand... I did a little ladder programming in a previous life, but the memory has faded. Any good reference texts on ladder programming, and especially on the various elements that are used?
