Omron SYSMAC NX series User Manual

The High-speed Analog Input Units convert input signals based on the Digital Filter Processing Pe-
riod. Converted analog input data is stored in moving average buffers to perform the moving aver-
age processing. If the moving average count is not reached, the analog input data stored in the buf-
fers is processed as moving average data. The moving average data is output as an analog input
value at the timing of sampling.
