The following I/O memory mapping lets you configure the 1769-OA8 module.

Output Module's Input Data File

For each module, slot , input data file word 0 contains the state of the module's
output data (output data echo) file word 0. During normal operation, these input
bits represent the logic state that the outputs are directed to by the control
program. They are also dependent upon these configurations:
Program mode configuration, if supported by the controller
Fault mode configuration, if supported by the controller
For the 1769-OA8, bits 8 to 15 are not used.

The output module's input data file reflects the output data echo of the
IMPORTANT
module, not necessarily the electrical state of the output terminals. It
does not reflect shorted or open outputs.
It is important to use this input word if the controller adapter supports
the Program mode or Fault mode function, and if it is configured to use
them.
