The greatly increased demands on communications in the automation solutions of modern systems and machines means that the wiring of individual signals is no longer practicable. In order to limit wiring effort and space required, data exchange must be performed by means of a fieldbus. The main reason for this is the increasing quality and quantity of signal to be exchanged. This tendency is particularly pronounced in the large amounts of diagnostic information that must be processed in monitoring functions, for example. Such a communications network fieldbus consists of a number of individual components such as controllers, drives, sensors, and actuators. On top of that, there are plugs, clamps, and other connectors as well as control units and visualisation systems. It is just in this fast-growing area that Bürklin Elektronik' range offers high-quality component for all commonly used I/Os and fieldbus systems.
