Understanding can be hard...
Terry Woods created a thread http://www.plctalk.net/qanda/showthread.php?t=22175&highlight=flip+flop
In that thread he shows how to create a flip-flop, one pb to alternate on/off of one output. In that thread he shows how to do it on virtually any plc with nothing but AND's and AND NOT.
I now understand that just because you can does not mean you should. Using some instructions may make the code hard to decipher for some.
I know many feel that noone needs to EVER look at their code etc...., but at some point it may be necessary.
Its hard enough just trying to learn all the instructions etc for different brands.
Why not get together and decide on ONE simple method, regardless of rung count etc., that will do the job and anyone should understand?
OHHH I forgot, y'all are engineers, my sincere apologizes.
