Key Points Industrial data exchange standard Used with automation and SCADA systems Supports vendor interoperability Predecessor and context for OPC UA Provides common interface for industrial data access Historically important bridge for industrial system integration Definition OPC is an industrial…
Key Points Analytical model used to predict maintenance need or failure risk Uses condition data, historical behavior, and operating patterns to estimate equipment degradation Enables maintenance planning before failure occurs Supports operational automation and improved asset management Cross-industry relevance in…
Key Points State Estimation is defined for network or system use. Inference of hidden or internal system state from available data. Used in operational and control contexts. Works by combining observations with a model to estimate values that are not…
Key Points Scan Cycle Time is the duration of one controller input-read, logic-execute, output-update cycle Used in PLCs, industrial controllers, and automation systems Affects controller responsiveness and the maximum rate of control updates Constraints include program size, input and output…
Key Points Industrial communication protocol for automation and field device connectivity Operates at the field-level communication layer in industrial systems Used in manufacturing, process systems, and installed industrial networks Many existing industrial installations continue to depend on Profibus Constraints include…
Key Points Enforces one-way data movement between domains Used to separate trusted and less trusted security domains Common in critical infrastructure and industrial security environments Prevents reverse flow of data across security boundaries Operates as a hardware or logical enforcement…
Key Points Designed for protective action rather than normal control Uses sensors, logic solvers, and final elements to detect hazardous conditions Initiates protective response before risk becomes unacceptable Distinct from normal process control because its purpose is protection Common in…
Key Points Integrated hardware and software used to control industrial or infrastructure processes Used in industrial automation and related system contexts Operates across manufacturing, utilities, energy, transport, and other industrial environments Includes sensors, controllers, actuators, and communications networks Supports physical…
Key Points Process Control is a defined function in industrial automation and control systems Regulation of industrial or physical processes toward target operating conditions Works by measuring process variables, comparing them with setpoints, and applying control actions Used in manufacturing,…
Key Points Detects or resists false timing inputs Supports secure synchronization Important where timing affects control or navigation Validates timing sources and compares multiple references Rejects inconsistent or suspicious timing inputs Definition Anti Spoof Timing is timing protection that detects…
