Introduction The introduction of electronics has resulted in great changes in industrial control engineering. Together with automated machinery, whose application possibilities were expanded through electronic controls, these changes have also led to new technologies and branches.
Controllers In addition to the energy supply, control elements are required for the operation of machines and processes in almost all areas of manufacturing. It must be possible to initiate, control and monitor the operation of any given machine or process.
In the past, control tasks were solved with conventional control technology by individually - that is, dependent on the task - wiring contacts and relays. Today programmable logic controls are largely used to solve automation tasks.
Totally Integrated In order for companies to remain competitive, it is not enough to isolatedly
Automation automate only individual processing stations or machines. The demand for more flexibility with higher productivity can only then be fulfilled when the individual machines are integrated in the entire system. The information flow between all components is essential for the functioning of the entire system.
Production processes are no longer seen as individual partial processes, but rather as integral components of an entire production process. Also, the entire process is also no longer structured centrally as hierarchical. Now the process is structured as distributed and autonomous individual elements.
The total integration of the entire automation environment is today made possible with the help of:
• common configuring and programming of individual partial systems
• common data management
• common communication between all participating automation components.
