Machine/Application/Device Module Relationship
The machine module monitors the current state of the overall machine and based on the state and/or requests from the HMI
terminal, broadcasts out commands to both the application and device modules. The individual modules perform a predefined
task based on the command. Some of the commands may be ignored depending on the module type.
Each of the modules are defined as individual programs in the Logix Project.
Each program contains all of the necessary logic to interact with the other configured modules. This interface between each of
the modules is accomplished via the Monitor and Control routines located in each of the programs. The machine commands and
corresponding module status is routed through the Monitor and Control routines. This lets the modules operate independently in
a modular structure.
