A communication protocol for a lighting control system having a plurality of control devices coupled to a communication link uses a polling technique to coordinate the transmission of digital messages between the control devices. When the control devices are powered up, one of the control devices is established as a "master" device. During normal operation, the master device transmits a standard poll message to each of the control devices in succession using a unique semi-permanent Poll ID for each of the control devices. The master device periodically transmits a Poll-ID-Request poll message to the control devices allow those devices that do not have a Poll ID to request a Poll ID. If a control device determines either that the master device is not transmitting poll messages to it, or that another control device has the same Poll ID, the control device drops its Poll ID and acquires another Poll ID.

L'invention porte sur un protocole de communication pour système de commande d'éclairage qui comprend une pluralité de dispositifs de commande couplés à une liaison de communication, lequel protocole de communication fait appel à une technique de sondage pour coordonner la transmission de messages numériques entre les dispositifs de commande. Lors de la mise sous tension des dispositifs de commande, l'un des dispositifs de commande est établi comme dispositif "maître". Au cours d'un fonctionnement normal, le dispositif maître transmet à chacun des dispositifs de commande successivement un message de sondage standard en utilisant un ID de sondage semi-permanent pour chacun d'eux. Le dispositif maître transmet périodiquement aux dispositifs de commande un message de sondage "demande d'ID de sondage" afin de permettre aux dispositifs qui ne possèdent pas d'ID de sondage de demander un ID de sondage. Si un dispositif de commande détermine que le dispositif maître ne lui transmet pas de messages de sondage, ou qu'un autre dispositif de commande possède le même ID de sondage que lui, le dispositif de commande abandonne son ID de sondage et acquiert un autre ID de sondage.
