Moving Average
Processing
This function calculates the average value (moving average) of the previous
eight inputs, and uses the resulting value as conversion data. When the input
value fluctuates frequently, averaging can be used to produce a stable input
value, as shown in the following diagram.
Setting Procedure (Example: DeviceNet Configurator)
1,2,3... 1. In the Network Configuration Window for the Slice I/O Terminal, double-
click the icon of the Analog Input Unit that is to be set. Alternatively, right-

be performed, and select the Moving Average Check Box in the Function
Choice Area.
5. Return to the General Tab Page, click the Download Button, and then
click the Reset Button to reset the Unit.
6. Click the OK Button to exit.
Scaling The default setting is used to perform AD conversion of analog input values,
scaling them to a count between 0 and 6,000. Scaling can be used to change
scaled values that correspond to the input signal range into other values
required by the user (industry unit values). Scaling also eliminates the need
