Hood and Others.....
I tell you this, if your using ADC products and you have a complex thing to do, STAGE LOGIC will be the best thing you have ever done!!
I break all my stuff up into stages (think of them as pockets of latter logic that perform specific functions), in your stage program, you can call these
"sub-routine like" pockets of ladder. That way you dont have layers, and layers, layers of interlocks to try and keep track of. The only Code that will
run on a scan is the one whos stage or stages are active.
