Error Detection Error Detection is the process of identifying whether data has been altered or corrupted. It is used to confirm that information arrived intact. Protocol Ethernet/IP Ethernet/IP is an industrial network protocol that uses Ethernet infrastructure to carry automation communication between controllers, devices, and I/O systems. Protocol Fail Safe Fail Safe is a design principle in which a system defaults to a safe state when a failure or abnormal condition occurs. It prioritizes safety over continued operation. Operations Fail-Operational System Fail-Operational System is a system designed to continue operating after a fault, often with reduced capability rather than immediate shutdown. It preserves operation through failure conditions. Operations Failure Domain A failure domain is the set of components or functions that share a common risk of concurrent failure because they depend on the same underlying element. Concept/Framework Fatigue Monitoring System A system that detects signs of operator drowsiness or impaired alertness in real time, commonly through computer-vision-based eye and facial monitoring, triggering an alert or intervention before fatigue-related performance degradation… Concept/Framework Fault Classification Fault Classification is the process of categorizing an observed fault condition into one of a defined set of fault classes so that a system or operator can apply the correct… Concept/Framework Fault Detection And Isolation Fault Detection And Isolation is the process of identifying that a fault has occurred and determining where it is located or what component caused it. Operations Fault Management System Fault Management System is the logic and supporting software that detects, isolates, and responds to faults within a platform or subsystem. Software Fault Tolerance Fault Tolerance is the ability of a system to continue operating correctly despite component failures or errors. Operations
