OBJECT ORIENTED TIMED MESSAGING SERVICE FOR INDUSTRIAL ETHERNET: A FIELDBUS LIKE ARCHITECTURE FOR POWER PLANT CONTROL AND FACTORY AUTOMATION

摘要

This paper describes an object oriented timed industrial messaging service suited to industrial Ethernet. We use an object oriented middleware technology able to run over Ethernet and TCP/IP. This framework addresses fieldbus architectures for power plant control and factory automation. The services provided by our prototype for data access are similar to the one offered by TASE.2. TASE.2 is a companion standard of the ISO Manufacturing Message Specification, dedicated to the utility domain. More precisely our work maps a subset of the TASE.2 specification to an ORB environment. We are interested to TASE.2 block 1 (periodic data exchange), block 2 (event based data exchange), and block 5 (device control). Our services are specified with CORBA IDL. Our result has a general scope and can be used for any factory network built on top of industrial Ethernet.
