I am not much of a programmer but about 2 years ago I made a 'cheap n cheerful' little unit that dispensed chemicals.
I used a binary selector switch to give me 0 to 7 selections using only 3 inputs.
Each one of those '8' selections set a different time to the dispensing valve.
They now want more time selections and I have 3 inputs spare but for the life of me I can't work out how many extra selections I can have with 2, 3 input binary switches.
I think 16, but maybe it's a lot more
Can you help
Oh, the plc is a small Mitsubishi FX 1n
