Hey everybody,
I recently discovered what kind of overhead is involved in polling several channels on the same cFP module separately (the software has to ping the module via ethernet each time) so I've been going through my code and updating it to poll a module and pull the data needed from there.
This was easy enough on all my DIs (although bit masking is something I haven't done in years), but I'm at a loss with my AIs. If I scale them in MAX, they come out with ridiculous values. If I don't scale them in MAX, they come out looking fairly normal, but some are still ridiculous.
Just for clarity, the original instance was me polling AI-111-ch0, then AI-111-ch1, etc.
Now, I poll AI-111-ch0/1/3/4/5/6 etc etc, but with ununsed channels interspersed (I didn't wire it, so don't look at me).
Should I set the FP I/O Point to only include the used channels, and would they then be sorted in the data array after an FP Read? Or should I include all channels, and then index the FP Read array by channel number? Nothing seems to be working.
