Compatibility Precautions for replacement
The conversion speed of Q68ADV/I
to A616AD has become quick. And
then, on Q68ADV/I, the noise that did
not import on A616AD can be
imported as analog signal. In this
case, use the averaging
processing
function to remove the effect of noise.
Consider
replacement with multiple
Q68ADV/I.
I/O occupied points has changed to
