Hello,
I'm new to this forum.
I have a problem to solve and I want to ask for some guidance (not a solution).
It's a conveyor belt with small and long baskets. Small ones are to be ejected further along the belt.
My question is: does Siemens S7-300 have any sort of memeory that I can store info that the small basket has been detected and will use this info after some time (when the small basket arrives at the point of ejection), while the detectors are busy surveying another basket?
At the moment, once the small basket is detected and is heading on its way to the ejector, the detectors may detect a long basket and disarm the ejector before small basket arrives. (According to my current logic).
I thought of inserting a shift register and then fire an ejector on timer. But I think it's too difficult for me. I'm a begginer.
So my question is: can it be done just with timers? Or combinantion of timers and counters?
Does it require something called subrutine?
Thanks,
Kch
