I/O Memory Mapping
Output Data File
For each output module, the output data file contains the controller-directed state of the discrete
output points. Bit positions 0…7 correspond to output terminals 0…7.
w = write only, 0 = always at a 0 or OFF state
Addressing
The 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.
