What is required for every module to operate in a ControlLogix system?

In a ControlLogix system, every module requires an owner that holds the I/O configuration. This is essential because, in the ControlLogix system architecture, each module, such as Input/Output modules, communicates and functions based on the configuration and control provided by the controller. The controller acts as the primary decision-maker in the system, managing how the modules interact with each other and ensuring that the data is processed correctly.

Having an owner for the I/O configuration means that the system maintains a clear structure and organization, allowing the controller to efficiently map signals from I/O devices to internal variables and control logic. This ownership is critical to making the system robust and ensuring that all modules function correctly within the larger framework of the ControlLogix environment.

While a power source is also necessary for module operation, it is not the unique element that defines the system's interaction and configuration. Similarly, while communication and network access may be important for data transfer, it is the established ownership of the I/O configuration that fundamentally organizes how the modules operate together in response to program logic and control strategies.
