Key Points Process Variable is the measured value used by a control system It exists to represent the current state of the process relative to a target The process variable is compared with a setpoint to determine control action Used…
Key Points Process Gain is defined for network or system use Ratio or relationship between input change and output change Used in operational and control contexts Characterizes process sensitivity and supports control tuning Controller settings depend on how strongly the…
Key Points Control Signal Resolution is the smallest representable change in a control signal Used in operational and control contexts Exists to describe the granularity of a control output Used in industrial automation, instrumentation, and motion systems Resolution affects how…
Key Points Phase Alignment is the adjustment of phase relationship between signals or clocks Used across network and system environments to support coherent transmission Critical in radio systems, clocks, signal processing, and industrial synchronization Requires measurement of relative phase difference…
Key Points Separates onboard traffic domains Improves security and policy enforcement Common in connected vessels and OT environments Often separates operational, crew, guest, and control traffic Operates at the Access layer with compliance implications Definition Vessel Network Segmentation is the…
Key Points Adjustment of control parameters for desired loop response and stability Used in operational and control contexts Balances overshoot, settling time, and steady-state error Essential for industrial automation, process control, robotics, and regulated physical systems Definition Control Loop Tuning…
Key Points Feedback Control is defined for network or system use Control method based on measured output and corrective action Used in operational and control contexts Foundation of most closed-loop regulators Definition Feedback Control is a control approach that uses…
Key Points Monitors software liveness Triggers recovery on timeout Used in embedded and critical control systems Detects stalled, hung, or unresponsive behavior Expects periodic service or heartbeat events from software Definition Watchdog Timer is a timer that resets or triggers…
Key Points Built for industrial automation communication Supports controller, device, and I/O interaction Often used with deterministic or prioritized traffic Integrates with plant and machine systems Runs over Ethernet infrastructure Supports cyclic and acyclic data exchange Definition Profinet is an…
Key Points Uses feedback to regulate behavior Found in industrial and automation systems Supports stability and setpoint tracking Can be open or closed depending on design Continuously or periodically senses process state, calculates error relative to desired state, and adjusts…
