Hi!
I've found this on
cFP-AI-110 Operating Instructions, pag. 8:
"The filter setting determines the rate at which the [c]FP-AI-110
samples the inputs. The [c]FP-AI-110 resamples all of the channels
at the same rate. If you set all of the channels to the 50 or 60 Hz
filter, the [c]FP-AI-110 samples each channel every 1.470 s or
every 1.230 s, respectively. If you set all of the channels to 500 Hz
filters, the module samples each channel every 0.173 s. When you
select different filter settings for different channels, use the
following formula to determine the sampling rate.
(number of channels with 50 Hz filter) ×184 ms +
(number of channels with 60 Hz filter) ×154 ms +
(number of channels with 500 Hz filter) × 21.6 ms =
Update Rate"
