What does "i" and "r" mean
« on: September 30, 2003, 07:33:08 PM »
I couldn't find in manual what the little i and r meant in the ladder diagrams (i.e. next to start, relay symbols, etc.)  I'm new to all this so need to ask this simple question.

Thanks

A little "i" means that the contact is an input, "o" means output, "r" means internal relay, "t" means timer and "c" means counter.

You can press the <F3> key to toggle whether to display this little "i","r" etc.
