The input data file lets you access module input read data for use in the control
program, via word or bit access. The data file structure is shown in the table
below. For each module, word 0, bits 0
values of the real inputs. For each module, word 1, bits 0
file contain the state of the module's output control circuits.

TIP
Direct Control of Module Outputs
The module's outputs can be directly determined by the control program
when the outputs are configured to have Boolean Control disabled.
Refer to Output Control (DB) on page 51, for information on configuring the
module's outputs for direct control mode.
When a module output has Boolean Control disabled, the directed state of that
output is controlled by the corresponding bit (OUT0 through OUT3) in the
output data file. Setting the bit (1) turns the output ON, clearing the bit (0)
turns the output OFF.
