Input Memory Map
For each input module, the input data file contains the current state of the field input points. Bit
positions 0…15 correspond to input terminals 0…15.
r = read only 0 = always at 0 or OFF state.
The input addressing scheme for 1762 expansion I/O is shown below.
(1) I/O located on the controller (embedded I/O) is slot 0. I/O added to the controller (expansion I/O) begins with slot 1.
