Redundant Subsystem Redundant Subsystem is a backup or duplicate subsystem that can maintain or restore function if the primary subsystem fails. It adds fault tolerance through duplication. Hardware Refuge Chamber Communications The communication systems and equipment integrated into underground mine refuge chambers, typically combining multiple independent methods — through-the-earth transceivers and hardened cable-based connections — to maintain a survivable communication path… Hardware Remote Operations Remote operations is the management of assets, processes, or services from a distant control location using communications, telemetry, and supervisory tools. It may include oversight, control action, troubleshooting, and escalation. Operations Remote Terminal Unit A Remote Terminal Unit is a field device that collects telemetry and communicates control or status data for remote operations, commonly used in SCADA systems to extend monitoring and control… Hardware Robotics Robotics is the design and operation of machines that sense their environment, process input, and act on the physical world. Concept/Framework Safe Mode Safe Mode is a reduced-function operating state entered to protect a system after a fault, anomaly, or loss of normal control. It preserves safe operation. Operations Safety Instrumented System Safety Instrumented System is a protection system that monitors conditions and takes automatic action to bring a process to a safe state when needed. It exists to reduce hazardous outcomes. Operations SCADA SCADA is a supervisory control and data acquisition system used to monitor and control distributed industrial processes. It collects telemetry from field devices and supports operator actions. Operations Scan Cycle Time Scan Cycle Time is the time required for a controller to read inputs, execute logic, and update outputs once in a control loop iteration. Operations Secure Remote Access OT The set of controls and architecture enabling authorized remote connectivity into operational technology systems for diagnostics, maintenance, or monitoring purposes, implemented to preserve IT-OT boundary security rather than granting unrestricted… Concept/Framework
