A multiplexer implemented substantially in the form of software, which enables the multiplexer to be integrated with a supervisory platform into one unit. The multiplexer may contain a database which stores a mapping of the address of the devices to the corresponding port/channels to which the devices are connected. An emulation block implemented in software examines the address in each command/response and forwards the command/response appropriately. Due to the software implementation, some of the commands may be blocked (from being forwarded). According to another aspect, data required to generate a response may be retrieved from a controller block (instead of retrieving from the device), thereby reducing the overhead on the devices.

L'invention concerne un multiplexeur implémenté pratiquement sous forme de logiciel, ce qui permet au multiplexeur d'être intégré à un plate-forme de supervision dans une unité. Ledit multiplexeur peut renfermer une base de données servant à stocker un mappage de l'adresse des dispositifs aux ports/aux canaux correspondants, auxquels sont connectés lesdits dispositifs. Un bloc d'émulation implémenté dans le logiciel permet d'examiner l'adresse dans chaque commande/réponse et d'envoyer la commande/réponse de manière appropriée. En raison de l'implémentation du logiciel, certaines commandes peuvent être bloquées (à l'envoi). Selon un autre aspect, des données requises pour engendrer une réponse peuvent être extraites d'un bloc du contrôleur (au lieu d'être extraites du dispositif), ce qui permet de diminuer le surdébit au niveau des dispositifs.
