Module Data, Status, and Configuration 43
1769-BOOLEAN Module Input Image
The 1769-BOOLEAN module input image file represents real input data
states and output state data echo. Input word 0 contains the state of the
module's real inputs IN 0 through IN 7 in bits 0
…
7. Input word 1 contains the
directed state of the module's outputs OUT0 through OUT3 in bits 0
…
3.
These output data echo bits indicate the state of the module's output control
circuits and do not represent the actual state of the outputs.
1769-BOOLEAN Module Output Image
The 1769-BOOLEAN module output image file represents directed output
states in Direct Control mode and virtual input data states. Output word 0
contains the states to which the module's outputs will be set when the outputs
are configured for Direct Control mode.
Module outputs OUT0 through OUT3 are set in Direct Control mode using
output file word 0 bits 0
…
3. Output word 1 contains the values of the virtual
inputs V0 through V7 in bits 0
…
7. These virtual inputs can be controlled in
the customer's user program and can be used in a module output's Boolean
expression when the output is configured for Boolean Control.
1769-BOOLEAN Module Configuration File
The 1769-BOOLEAN module configuration file contains information that
you use to define the module's operation.
The configuration file is explained in more detail in 1769-BOOLEAN Module
Configuration Data File on page 46.
TIP
You can access information in the input image file using the
programming software configuration screen.
TIP
You can access information in the output image file using the
programming software configuration screen.
TIP
Not all controllers support program access to the configuration
file. Refer to your controller’s user manual.
