A digital twin that places live data inside a 3D model of the plant, so every sensor and alarm appears at its physical location rather than as a tag name in a list.

Industrial IoT glossary
The factory-data vocabulary, in plain English.
39 terms you will meet when connecting machines, monitoring production, simulating lines, tracking assets and reporting carbon — each explained in a sentence or two.
- Simulation & digital twins3D spatial digital twin
- Simulation & digital twinsAgent-based modellingABM
Simulating individual actors — operators, AGVs, robots — each following their own rules, to see how their behaviour and interactions affect the whole system.
LinkSim- Connectivity & edgeAutonomous protocol discoveryAuto-detection
A gateway capability that scans its ports and network, identifies which protocol each connected device speaks and maps its data points automatically — instead of an engineer configuring every register by hand.
LinkEdge LE-100- Carbon complianceBEEBureau of Energy Efficiency
The Government of India agency under the Ministry of Power that administers energy-efficiency programmes and the compliance side of India's carbon market.
- Location & safetyBluetooth Channel SoundingBluetooth 6.0
A Bluetooth 6.0 feature that measures distance between devices using phase and round-trip timing, enabling accurate indoor positioning with low-cost tags.
LinkTrack- Simulation & digital twinsBottleneckConstraint
The step in a process that limits the output of the whole line. Improving anything other than the bottleneck does not raise total output.
LinkSim- Carbon complianceCarbon Credit CertificateCCC
A tradeable certificate issued under CCTS when a plant reduces its emission intensity beyond its target.
IronTrust- Carbon complianceCBAMCarbon Border Adjustment Mechanism
The European Union's mechanism that puts a carbon price on certain imported goods, such as steel, aluminium and cement, based on the emissions embedded in producing them.
IronTrust- Carbon complianceCCTSCarbon Credit Trading Scheme
India's carbon market framework, under which notified industrial plants must reduce their greenhouse gas emission intensity against targets and can trade Carbon Credit Certificates.
IronTrust- Simulation & digital twinsDigital twin
A live virtual model of a physical asset, line or plant, kept up to date with real data so teams can monitor, analyse and test changes without touching the real equipment.
LinkTwin- Simulation & digital twinsDiscrete-event simulationDES
Modelling a production system as a sequence of events — a job arrives, a machine starts, a machine breaks down — to predict throughput, queues and bottlenecks over time.
LinkSim- Location & safetyDwell time
How long an asset or batch stays in one place or zone. Long dwell times in staging areas signal waiting waste or bottlenecks.
- Connectivity & edgeEdge gatewayIndustrial gateway
A rugged device installed near the machines that reads data from PLCs, meters and sensors, converts it into a common format and sends it securely to dashboards or the cloud.
LinkEdge LE-100- Carbon complianceGEIGreenhouse gas emission intensity
Greenhouse gas emissions per unit of product — for example tonnes of CO₂-equivalent per tonne of output. CCTS targets are set as GEI reductions.
IronTrust- Location & safetyGeofenceMonitored zone
A virtual boundary drawn on a floor plan or 3D model. Rules trigger when a tracked asset enters, leaves or stays too long inside it.
LinkTrack- Monitoring & analyticsHMIHuman–machine interface
The screen an operator uses to see and interact with a machine or process — gauges, trends, alarms and buttons.
- Connectivity & edgeIIoTIndustrial Internet of Things
Connecting factory machines, sensors and controllers to software so their data can be collected, analysed and acted on — the industrial counterpart of consumer IoT.
What is Link360- Connectivity & edgeIndustrial protocolFieldbus, machine protocol
The "language" a machine or controller uses to share data, such as Modbus, OPC UA, PROFINET, EtherNet/IP or MTConnect. A plant often runs many of them side by side.
Protocols LinkEdge supports- Monitoring & analyticsISA-18.2Alarm management standard
The international standard for managing industrial alarms across their life cycle — so operators see fewer, more meaningful alarms.
- Monitoring & analyticsMESManufacturing execution system
Software that tracks and manages production on the shop floor — orders, output, downtime, quality and traceability — between the machines and the business (ERP) systems.
LinkVision- Monitoring & analyticsMicro-stoppageMinor stop
A short, often unrecorded interruption — a few seconds to a few minutes — that individually looks harmless but adds up to large hidden losses in output.
- Connectivity & edgeModbusModbus TCP / RTU
One of the oldest and most widely used industrial protocols. Modbus RTU runs over serial cables (RS-485); Modbus TCP runs over Ethernet. Data is read as numbered registers.
- Connectivity & edgeMQTT
A lightweight publish/subscribe messaging protocol widely used to stream IoT data from edge devices to servers and cloud platforms.
- Carbon complianceMRV / dMRVMonitoring, reporting & verification
The process of measuring emissions, reporting them and having them independently verified. Digital MRV (dMRV) automates this with data captured directly from equipment.
IronTrust- Connectivity & edgeMTConnect
An open standard for reading data from CNC machines and other machine tools — spindle speed, feed rate, program status, alarms and more.
- Monitoring & analyticsOEEOverall equipment effectiveness
A standard measure of how productive a machine or line is: Availability × Performance × Quality. 100% means producing only good parts, as fast as possible, with no stops.
LinkVision- Connectivity & edgeOPC UAOpen Platform Communications Unified Architecture
A vendor-neutral industrial standard for exchanging machine data securely, with built-in information models that describe what each value means.
- Monitoring & analyticsP&IDPiping and instrumentation diagram
An engineering drawing of a process showing pipes, valves, pumps, instruments and control loops. Often the starting point for SCADA screens.
LinkVision- Connectivity & edgePLCProgrammable logic controller
The industrial computer that controls a machine or process — reading inputs such as switches and sensors and driving outputs such as motors and valves. Most machine data starts here.
- Monitoring & analyticsPredictive maintenance
Using live sensor data — vibration, temperature, current and more — to spot equipment degradation early and plan repairs before a breakdown, rather than on a fixed schedule or after failure.
LinkVision- Location & safetyRTLSReal-time location system
Technology that continuously tracks where tagged assets, vehicles and people are inside a building, using fixed anchors and wireless tags.
LinkTrack- Monitoring & analyticsSCADASupervisory control and data acquisition
Software that shows live process and machine status to operators, raises alarms and, where permitted, lets them send commands back to equipment.
LinkVision- Location & safetySpaghetti diagramTravel map
A map tracing the actual paths people and vehicles take across a facility, used to expose unnecessary travel and congested routes.
LinkTrack- Connectivity & edgeStore-and-forwardEdge buffering
Keeping data in local storage on the gateway when the network link drops, then sending it once the link returns — so no readings are lost during outages.
LinkEdge LE-100- Connectivity & edgeTagData point, signal
A single named value read from a machine — for example a temperature, a counter or a motor current. A plant can have thousands of tags.
- Monitoring & analyticsTime-series historianProcess historian
A database built to store large volumes of time-stamped machine data for trends, playback, analysis and audits.
- Location & safetyUWBUltra-wideband
A short-range radio technology that measures distance very precisely, used for high-accuracy, high-refresh indoor positioning of fast-moving assets.
LinkTrack- Monitoring & analyticsVibration FFT analysisFast Fourier transform
Breaking a vibration signal into its frequency components. Specific frequencies point to specific faults such as bearing wear, imbalance or misalignment, often weeks before failure.
- Simulation & digital twinsWhat-if scenario
A simulation run that tests a proposed change — a new machine, a different shift pattern, a new layout — before any money is spent on the real floor.
