Efficient Way to Detect Large Number of Inputs in Logic

[cwal61]

Wow, didn't know we had so many FSC haters. I still say that's the way I would do it. Making AOI's or UDT's!!!! talk about a Bubba Stumper. I would align my array with the bin Number 1-125 and use Control.pos for Fault detection and Display. A simple expression [ArrayInput1 <> ArrayOutput1] and one line of code. If Control.Fd for Time then Fault.

FSC will find the bits...that's not the issue. The issue is all the logic required to set them in the first place.

I can name that tune with 2 lines of Logic.

I wouldn't call a UDT a bubba stumper. If anything, a well constructed UDT should make it clearer to Bubba.

If he can't understand XIC Bin[1].Door_Is_Open then he should not be in there at all.

Alaric, I Agee but if we are going to Assume Bubba can Read... Then A Rung Comment would fix any problem.

I personally would use a UDT, exploring a single timer for both functions. View your current scan time to see if your anywhere close to your 'bounds'. You could probably go over your code and free up a bunch of space by reassigning bools if need be.

Wouldn't the DDT do what is required?

Doug,

I believe this instruction (DDT) changes the reference to match the source after the comparison. This compares DINT array's(double words) and not bits. So not sure if this will work. But this could come in handy one day. Did not know this even existed.

Thanks.
