CA 2379038

A master controller (28) in a control area network system in a larger control area network (16, 18) may have a plurality of devices (33) coupled thereto. The master controller may further include a device manager (51) which provides a virtual device (58). The virtual device operates to link a state associated with the virtual device to a plurality of states associated with the devices such that the respective states are maintained in a substantially similar condition. The substantially similar condition is maintained by propagating a change in the state of the virtual device to a change in the state of the devices and a change in the state of one or more of the devices is propagated to the virtual device and all other devices.

L'invention concerne un contrôleur (28) maître d'un système de réseau de zone de commande se trouvant dans un réseau (16, 18) de zone de commande plus vaste, ledit contrôleur comprenant une pluralité de dispositifs (33) qui lui sont couplés. Le contrôleur maître peut également comprendre un gestionnaire (51) de dispositif constituant un dispositif (58) virtuel. Ce dispositif virtuel sert à relier un état associé au dispositif virtuel à une pluralité d'états associés aux dispositifs de façon à maintenir les états respectifs dans un état sensiblement similaire. Cet état sensiblement similaire est conservé par émission d'une modification de l'état du dispositif virtuel applicable à l'état des dispositifs, une modification de l'état d'un ou de plusieurs dispositifs étant émise vers le dispositif virtuel et tous les autres dispositifs.
