What occurs when the controller encounters a minor fault?

When a controller encounters a minor fault, it is designed to continue running while maintaining its operational integrity. This approach is vital in industrial applications where continuous operation is crucial, even in the face of less critical issues. The logic behind this design is to avoid unnecessary downtime which could disrupt production processes, and instead, the system can often still perform safely or in a degraded mode.

In cases of minor faults, the controller may alleviate the specific problem while logging the fault for later analysis or action. This allows operators time to assess the situation without immediate panic or the need for manual intervention. It fosters a more resilient system that can handle less severe faults gracefully rather than shutting down completely or requiring a reboot, which could be disruptive. This design philosophy ensures that systems remain operational and allows for better fault tolerance.
