A multi-protocol smart field device uses a Fieldbus communication protocol to communicate process control information and uses a HART communication protocol to enable local configuration of the field device via a hand-held HART communicator. The multi-protocol smart field device includes a first communications interface communicatively coupled to a digital data bus that is adapted to process HART communications which are received from and which are sent to a HART hand-held communicator. The multi-protocol smart field device further includes a second communications interface communicatively coupled to the digital data bus that is adapted to process Fieldbus communications. Additionally, the multi-protocol smart field device includes a first filter coupled between the first communications interface and the digital data bus that substantially attenuates signals having frequencies associated with Fieldbus communications and a second filter coupled between the second communications interface and the digital data bus that substantially attenuates signals having frequencies associated with HART communications.

L'invention se rapporte à un dispositif de champ intelligent multiprotocole utilisant un protocole de communication Fieldbus afin de communiquer des informations de commande de processus, et utilisant un protocole de communication HART afin de mettre en place une configuration locale du dispositif de champ au moyen d'un communicateur HART émetteur-récepteur portatif. Ce dispositif de champ intelligent multiprotocole comprend une première interface de communication qui est couplée de manière communicante au bus de données numériques conçu de manière à traiter des communications HART reçues depuis et transmises vers un émetteur-récepteur portatif HART. Ledit dispositif de champ intelligent multiprotocole comporte également une seconde interface de communication qui est couplée de manière communicante au bus de données numériques adapté de manière à traiter des communications Fieldbus. De plus, ce dispositif de champ intelligent multiprotocole comprend un premier filtre couplé entre la première interface de communication et le bus de données numériques qui atténue sensiblement les signaux dont les fréquences sont associées aux communications Fieldbus, et un second filtre couplé entre la seconde interface de communication et le bus de données numériques qui atténue sensiblement les signaux dont les fréquences sont associées aux communications HART.
