7.2  Program Examples

Conditions in the program

This program reads digital output values from the A/D converter module's CH1, CH3, CH5, and CH7 where A/D conversion is 
enabled.
The A/D conversion takes place in CH1 and CH7 by means of sampling processing; in CH3 by means of averaging 
processing for 50 samples; and in CH5 by means of moving average for 10 samples.

Parameter settings

Perform initial settings in the parameter settings of the engineering tool. The auto refresh setting does not need to be changed 
here.
For details on the parameter settings, refer to the following.
