The basic concepts that can be found in the relevant international standards have been taken as a basis for the development of the model. The model is formally described in Express since it is a well assessed data modeling language for which a graphical subset also exists. Several tools for processing Express models are widely available nowadays on different platforms. Hence, the model can be translated into a corresponding representation for a specific host language with relatively little effort. The basic aim is that of providing a common understanding of the device features through the structured organization of data, parameters, event and actions so that interoperability is guaranteed independently of the specific fieldbus technology used in the network. Each device is described using the entity relationship approach and takes advantage of the inheritance property which leads to a simple and immediate description of new device features which can be added to the hierarchy without affecting the existing structure of the model. As an example, the paper also shows how the proposed general model can be refined to describe a particular class of real devices including more specific attributes and events.","PeriodicalId":433593,"journal":{"name":"Proceedings 1997 IEEE International Workshop on Factory Communication Systems.

These devices communicate through particular common bus networks, called fieldbuses, using communication protocols developed to guarantee precise delivery times for the variables transmitted. In process control environments, different control units may need to share the data collected by a sensor, or to broadcast processed data to the various actuation units. Thus, transactions involving one producer and several consumers of a real time variable have to be supported. The transaction model proposed is based on the definition of a group associated to each real time variable. A group is a set of entities comprising the producer of the variable and its consumers. The paper proposes a time constrained group communication approach for real time distributed process control, and presents two transaction models suitable for the scenarios typical of Industrial Process Control & Measurement Systems. In particular, the authors focus on the mapping of the group communication model onto the data link layer protocol of the IEC/ISA FieldBus, as it provides a series of facilities which help the application process to check that some of the required time constraints are met.","PeriodicalId":433593,"journal":{"name":"Proceedings 1997 IEEE International Workshop on Factory Communication Systems.
