Note Word (n + 1) can be used for either the range code or the analog output set
value.
Connecting the Analog I/O
Unit and Setting the DIP
Switch
This section describes how to connect an Analog I/O Unit to the CPU Unit.
Setting the Averaging Function
DIP switch pins 1-1 and 1-2 are used to set the averaging function. When
averaging is enabled, a moving average of the last eight input values is output
as the converted value. The averaging function can be set separately for ana-
log inputs 1 and 2.
