Patent

CA 2653020

In a field device (1) for use in an AS-interface network (2), the invention proposes implementing a different number of logic slaves (3) on the basis of the allocated address, which slaves can be addressed in the standard mode or in the extended addressing mode using the allocated address. It is thus possible to provide slaves having different profiles in a field device, which can be used to interchange different types of data. A method which can be used to address a field device having different slaves in a simple manner while avoiding double addressing is also proposed.

La présente invention concerne la réalisation, dans un appareil de terrain (1) pour l'utilisation dans un réseau d'interface AS (2) en fonction de l'adresse attribuée, un nombre différent d'esclaves logiques (3) qui peuvent être interpellés en mode d'adressage standard ou avancé avec l'adresse attribuée. Ainsi, des esclaves peuvent être mis à disposition dans un appareil de terrain avec différents profils, lesquels permettent d'échanger différents types de données. L'invention concerne en outre un procédé permettant d'adresser un appareil de terrain avec différents esclaves en évitant de manière simple les adressages doubles.
