Terms in Industrial IoT

The entries explain technical terms from the Industrial IoT and lead to the service in which they occur.

A

AASAsset Administration Shell
Standardised digital image of an asset according to IEC 63278 that describes data and functions in submodels in machine-readable form. Administration shell and product passport
Anomaly detection
Method that finds deviations from normal behaviour in measured data, for example unusual vibrations of a spindle. Data analysis and forecasting
Aurora
Data Acquisition and Monitoring Suite of IQstruct Engineering. It connects controllers, machines and measuring devices via common industrial protocols and processes the data without programming. Middleware and data flow

B

BACnetBuilding Automation and Control Networks
Communication protocol of building automation according to ISO 16484-5 for heating, ventilation, air conditioning and access. Building and process automation
Broker
Central instance in MQTT that receives the messages of the senders and passes them on to all receivers with a matching subscription. Middleware and data flow

C

Campus network
Private mobile network on a company site, for example based on 5G, with its own frequency and its own administration. Network and wireless
Cloud
Computing power, storage and services are provided over the internet from the data centres of a provider. Cloud and third-party systems
Condition monitoring
Continuous measurement of condition variables of a machine that makes wear and deviations visible early. Predictive maintenance

D

Dashboard
Screen view that summarises key figures and measured values in charts and gauges. Production data and analysis
Digital twin
Digital image of a plant, a machine or a product with geometry, behaviour and data. It accompanies the object through planning, operation and conversion. Automation & Virtual Commissioning
DPPDigital product passport
Digital data record under the EU Ecodesign Regulation that describes origin, composition, repair and recycling of a product. Administration shell and product passport

E

Edge computing
Data are processed close to the machine on a device in the plant before they go to central systems or a cloud. Edge hardware
Edge device
Industrial computer at the machine that acquires data from controllers and sensors, pre-processes them and passes them on. Edge hardware
Energy monitoring
Continuous measurement and analysis of the energy consumption of plants, buildings and supply networks. Energy data management
ERPEnterprise resource planning
Business software for orders, materials, purchasing, warehouse and finance of a company. Cloud and third-party systems
EtherCATEthernet for Control Automation Technology
Real-time Ethernet fieldbus in which one telegram serves all nodes as it passes through. Industrial protocols

F

Fieldbus
Bus system that connects field devices such as sensors and actuators to the controller. Industrial protocols

G

Gateway
Device or software that translates between two protocols or networks, for example from a fieldbus to MQTT. Middleware and data flow

I

IDTAIndustrial Digital Twin Association
Association that develops the Asset Administration Shell as an open standard and publishes submodels. Administration shell and product passport
IIoTIndustrial Internet of Things
Networking of machines, sensors and controllers in industry whose data are acquired, transmitted and analysed. Industrial IoT
IO-Link
Point-to-point interface according to IEC 61131-9 through which sensors and actuators transmit parameters and diagnostic data in addition to the switching signal. Data acquisition and connectors
ISO 50001
International standard for energy management systems according to which a company records, evaluates and systematically reduces its energy consumption. Energy data management

L

LoRaWANLong Range Wide Area Network
Radio standard for small amounts of data over long distances at low energy demand, suited to battery-powered sensors. Network and wireless

M

MESManufacturing execution system
Production control system that steers orders on the shop floor, records machine and operating data and reports back to the ERP. Cloud and third-party systems
Middleware
Software between data sources and target systems that collects, converts, buffers and distributes data. Middleware and data flow
Modbus
Widely used protocol that reads and writes the registers of a device over a serial line (Modbus RTU) or Ethernet (Modbus TCP). Industrial protocols
MQTTMessage Queuing Telemetry Transport
Lean protocol based on publish and subscribe. A broker distributes the messages between senders and receivers. Industrial protocols

N

NB-IoTNarrowband Internet of Things
Mobile radio standard for sensors with small amounts of data that also connects inside buildings and basements. Network and wireless

O

OEEOverall equipment effectiveness
Key figure calculated from availability, performance and quality of a plant. Production data and analysis
OPC UAOpen Platform Communications Unified Architecture
Vendor-independent standard for secured data exchange between machines, controllers and IT systems, with its own information model. Industrial protocols

P

PDA/MDAProduction data acquisition and machine data acquisition
Acquisition of order, personnel and machine data in production, for example quantities, running times and downtimes. Data acquisition and connectors
Predictive maintenance
Maintenance that schedules service from condition data such as vibration, temperature or current draw before a failure occurs. Predictive maintenance
PROFINETProcess Field Network
Industrial Ethernet protocol for real-time exchange between controllers and field devices. Industrial protocols

S

Submodel
Building block of an Asset Administration Shell that describes one aspect of an asset, for example nameplate, technical data or carbon footprint. Administration shell and product passport

Database that stores measured values with a time stamp and answers queries over periods quickly. Production data and analysis

W

WLANWireless local area network
Radio network according to IEEE 802.11 for computers, tablets and mobile devices in office and hall. Network engineering
