Interconnecting fieldbuses through ATM
نویسندگان
چکیده
Networks in the area of factory automation, named field-buses, have been developed to fulfill real-time requirements. However, they can only cover areas such as factory halls or buildings. This paper describes a model for a internetworking unit connecting field-buses via ATM networks, in order to break these limits. A remote bridge is used to span longer distances between field-bus components in a separated field-bus. The second version of a bridge acts like a multiport bridge connecting several independent field-buses. The emphasis is laid on the investigation to the quality of service requirements the transport channel provided by the ATM network has to meet. By means of the wide spread field-bus PROFIBUS, standardized by the German standardization office, the implications for real-time applications and the system behavior are considered.
