Key Points Collects data from distributed points Supports monitoring and automation Used in industrial and environmental systems Often combines sensing and communications Operates at the Access layer connecting field devices to control and analytics systems Enables visibility into physical conditions…
Key Points Management Plane separates management functions from forwarding and decision-making functions Provides interfaces and processes for operators or tools to manage system behavior Used in routers, switches, cloud systems, and operational platforms Requires secure, out-of-band reachability independent of user…
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 Buffers messages between systems Supports asynchronous processing Common in distributed architectures Helps decouple producers and consumers Absorbs bursts and smooths workload differences Improves resilience through loose coupling Definition Message Queue is an asynchronous messaging system that stores messages…
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 Alignment of system time values across devices or platforms Used to coordinate logging, control, scheduling, and event ordering Operates across telecom, industrial systems, distributed computing, and measurement environments Supports consistent interpretation of when events occurred Definition Time Synchronization…
Key Points Control method that acts before error grows large Responds to input conditions or disturbances in advance Often combined with feedback control for better performance Used in industrial automation, process control, and systems with known disturbances Definition Feedforward Control…
Key Points Preserve local autonomy while cooperating Used in political, operational, and network contexts Can describe federated cooperation structures Often imply shared objectives with independent control Coordination without full centralization Definition Confederations are groups of autonomous systems or organizations that…
Key Points Alarm Management System is a software system for handling alarms and operator notification Used in operational and control contexts Prevents operators from being overwhelmed by too many or poorly designed alarms Used in industrial automation, control rooms, utilities,…
