5. Q: I feel that the reaction time of analog module in I-87K is slow. Why

does it?
A: It is due to low sampling rate. Beside the I-87017 series module,
the remainder analog input module has sampling rate with 10Hz
maximum. If you want to use the high sampling module, I-8017H and
I-87017 is the best choice.

6. Q: how can I use the additional function of I-87082?

A: Please refer to the “

Byte Order and Data Address”

chapter in

the PROFI-8455 user’s manual.
