It occured to me if a person is teaching themselves PLC programming
I do something that may help others like me. Lets say you want to
increment a counter for what ever reason in your "practice" Ladder-Logic program;
instead of pressing a switch (that is hard wired to your input module)
ON and OFF all the time, use the REAL TIME CLOCK(S42/0) of the PLC(I'm using SLC 5/03).
Using a XIC contact, address the contact as S42/0. Now the contact opens
and closes one second at a time. Place this contact in front of a (lets say)
up-counter and now the counter will increment 1 at a time per second; without you
having to touch anything. I hope this can maybe be helpful.
