(1) Filter
The analog I/O cartridge's analog input is filtered so it reaches approximately 99% of the analog input in the specified filter.
Even when the analog input varies rapidly, the filtered analog input value can be made to vary smoothly by setting the filter.
When the filter is set to a large value, the tracking of the filtered analog input value becomes slower in regard to the fluctuations
in analog input.
