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.
ATTENTION
EXPLOSION HAZARD
• In Class I, Division 2 applications, the bus connector must be fully
seated and the bus connector cover must be snapped in place.
• In Class I, Division 2 applications, all modules must be mounted in
direct contact with each other as shown on page 6. If DIN-rail
mounting is used, an end stop must be installed ahead of the controller
and after the last 1762 I/O module.
