INTERBUS has been developed as a sensor/actuator bus system for the transmission of process data to increase productivity of machines and plants, while at the same time cutting costs. Today the INTERBUS technology is known as mature and solidly and is standardized in the IEC 61158 and IEC 61784. With its special transmission procedure and ring topology, the INTERBUS system provides not only excellent performance characteristics, such as fast, cyclic and time-equidistant data communication, but also simple handling, comprehensive diagnosis functions to minimize downtime, as well as a high degree of immunity to interference by using fiber optics. It is these characteristics, in combination with the inexpensive connection of sensors and actuators that have led to the rapid acceptance of the fieldbus system. Currently (March 2014) there are over 18.6 million installed INTERBUS nodes available.

Due to the increasing change of fieldbus technologies in direction Ethernet for users the integration of the technology INTERBUS and the creation of efficient and investment-protecting migration ways are of essential meaning. Thus an optimum integration of INTERBUS into PROFINET has been created. The today's stable INTERBUS technology has just to be technically maintained. Hence, the former INTERBUS Club and PROFIBUS User Organization (PNO) have decided to integrate its maintenance activities into PI.
