Distributed Controllers

The decentralization of intelligence helps hugely in making machines and plants more flexible and is thus becoming a decisive competitive factor. Increasing networking makes it possible to integrate autonomous, intelligent units at the field level into the system-wide communication system. The SIMATIC ET 200 I/O system can be expanded using integral, intelligent controllers. This gives rise to Distributed Controllers.
