Input inhibit

[Steven58]

Hi all,

I have been asked by the company I work for to make some modifications to a Omron CP1L, using CX Programmer.

Part of the program, which I am working on has 12 inputs which turn on at random times, usually only 3 at any one time, and 12 outputs which corespondent to the 12 inputs, simple!

I have been asked to only let 3 outputs come on at any onetime( the first 3 that are requested) no matter how many inputs come on. If then 1 output goes off, this then will let another 1 output come on.

Any ideas how I can program this inhibit type system?

Thanks

Maybe the BCNT instruction could help you?
