Schedulability Analysis of Real-Time Traffic in WorldFIP Networks: an Integrated Approach

The WorldFIP protocol is one of the profiles that constitute the European fieldbus standard EN-50170. It is particularly well suited to be used in distributed computer-controlled systems (DCCS) where a set of process variables must be shared among network devices. To cope with the real-time requirements of such L. Almeida, E. Tovar, J. A. Fonseca and F. Vasques 2 / 29 systems, the protocol provides communication services based on the exchange of identified variables
