What is automation technology?

Automation technology is a field of engineering and information technology that deals with the development, implementation and optimisation of systems and processes for the automatic control and regulation of technical processes. The aim is to minimise human intervention in industrial and technological processes in order to increase efficiency, precision, productivity and safety. Automation technology encompasses various technologies and methods:

Automation systems:
Systems for controlling and monitoring processes. This can include the implementation of software, hardware and sensors for collecting and processing data.
Programmable logic controllers (PLCs):
Intended for the automation of machines and systems. PLCs enable the programming of logic and sequences for various applications.
Industrial robotics:
Use of robots and automated systems for tasks such as assembly, packaging, material transport and other industrial processes.
Sensors and actuators:
Integration of sensors for capturing environmental data and actuators for implementing control signals. This enables feedback and the control of processes.
Process control engineering:
Development of control systems for monitoring and controlling industrial processes. This includes the visualisation of process data and interaction with operating personnel.
Machine and system automation:
Automation of production processes, production systems and machines in order to improve efficiency, accuracy and quality.
Integrated systems and networking:
Integration of various automated systems and networking of devices via communication protocols, such as the Industrial Internet of Things (IIoT).
Process optimisation and control engineering:
Application of control engineering to optimise processes and to ensure compliance with specified parameters.

Automation technology and sensors

The connection between sensors, automation technology and the Industrial Internet of Things (IIoT) lies in their integrated application to create intelligent, networked and autonomous systems in industrial environments. Sensors continuously record data from the environment. In industrial applications, this can be temperature data, pressure measurements, vibrations, humidity values and much more. This data is used to monitor the condition of machines and processes. The collected sensor data is forwarded to automation systems in real time. These systems can make decisions based on the data and automatically execute actions to optimise processes or react to changing conditions. For example, the temperature in an industrial furnace can be controlled automatically. The IIoT enables the networking of sensors, automation systems and other devices. Sensor data can be transmitted wirelessly or via wired networks to central control systems or cloud platforms. This enables processes to be monitored, analysed and controlled centrally. The IIoT makes it possible to analyse large amounts of data (big data) in real time. This data analysis can be used to identify patterns, predict maintenance requirements, optimise processes and improve efficiency.

The seamless connection between sensors, automation technology and IIoT creates an intelligent, networked infrastructure that helps companies to make their production more efficient, reduce costs, improve quality and respond flexibly to changing requirements.

Sensors

Sensors are devices that detect physical or chemical properties of the environment and convert them into electrical signals. In automation technology, sensors are used to collect data on the condition of machines, environments or processes. This data can include parameters such as temperature, pressure, speed, position and many others.

Automation technology

Automation technology uses sensor data to control and monitor automated processes. By programming control systems, machines and systems are controlled in such a way that they function optimally and efficiently. Sensors play a crucial role here, as they provide the feedback and real-time information needed to automate processes.

Industrial Internet of Things (IIoT)

The IIoT refers to the networking of devices, sensors, machines and systems in industrial environments via the Internet. The IIoT extends conventional automation by enabling bidirectional communication between the various components and collecting and analysing large quantities of real-time data.
