■ Filter
The analog input is filtered so it reaches approximately 99% of the analog input in the set time. Rapid fluctuations in
the analog input can be reduced by setting the filter, but increasing the filter slows down the tracking of fluctuations
in the analog input. The filter must be set for each channel.

■ 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.
Filter Description
0 msec The value is not filtered.
50 to 50,000 msec
The analog input filter can be set in 50 milliseconds increments.
The analog input is filtered so that approximately 99% of the analog input is reached in the
specified filter.
