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

ddressing

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.
