When a module's I/O point fault LED displays a fault, which option is configured to allow these features?

The option that allows the features necessary for the I/O point fault LED to display a fault is enabling diagnostics. When diagnostics are enabled in a ControlLogix system, the controller can monitor the health and status of I/O modules and their point-level inputs or outputs. This includes detecting faults such as short circuits, open circuits, or other abnormalities that may affect operation.

With diagnostics active, the system provides real-time information about the status of each I/O point, and the fault LED can indicate any issues effectively, facilitating troubleshooting and maintenance. This capability is essential for ensuring the reliability and safety of control applications, as it allows operators and technicians to quickly identify and respond to faults that could impact the system's performance.

Other options, while relevant to different functionalities within the system, do not directly contribute to the ability of the I/O point fault LED to indicate a fault condition. They may serve different purposes, such as managing process alarms or filtering signals, but they do not directly engage with the fault detection mechanism that influences the LED status.
