Sampling Time
Analog values are converted to digital values at the interval of the sampling time. Depending on the analog I/O
module, you may be able to change the sampling time setting.

*1 When the
Sampling Time
is set to 30 milliseconds, the modules may be more easily affected by commercial power supply
noise (50/60 Hz noise) and fluctuations in input values may become larger. If there are large fluctuations in input values,
change the
Sampling Time
to 120 milliseconds.
