Chapter 3 ControlLogix Analog I/O Module Features
In integer mode, input modules generate digital signal values that correspond
to a range from -32,768…32,767 counts.
The table lists the conversions of a generated digital signal to the number
of counts.
Output modules let you generate an analog signal at the screw terminals that
correspond to a range from -32,768…32,767 counts.
