May be you should use specific module interrupt OB's |

Hello got_fr even though the basic conversion time per channel is 52 micro seconds, the basic execution time of the module is 0.42 milli seconds (assuming interference supression is set to "None", see the module specification manual for more). I'm afraid to say that what you are plannig to dowith this card (e.g. make an average value with 100 sample in less than 1 ms) is not possible. |

Hello got_fr
I wish I'd knew the answer to that (as this can be easily misleading unless you read the "fineprint" in the specification)
No (this is as good as it gets as far as I know)
You are bound by thecyclic or interrupt driven execution speed of the CPU. Ido wonder though why you needyour AI signal to be able to change faster than you can actually evalute it via the logic and as such react to it (what are you trying to do, perhaps there are other ways to achieve it)? I hope this helps |
