INTERFACE MODULE FOR USE WITH NETWORK OF DEVICES MODBUS AND NETWORK OF DEVICES FIELDBUS Russian patent published in 2009 - IPC G06F13/40 

FIELD: physics, guidance.

SUBSTANCE: invention concerns the automated control systems of technological process. Interface module is operatively related to the Fieldbus network of guidance of process and the Modbus network of guidance of process. The interface module stores a database of a card of registers in which parametres of guidance of processes and the functional blocks in field devices of the Fieldbus network of guidance are mapped by process under numbers of registers of network Modbus of guidance of process. After mapping of parametres Fieldbus of guidance by process in registers Modbus, the interface module is adapted to transmit messages-inquiries on network Fieldbus of guidance of process to field devices Fieldbus for current values of parametres of guidance of process. And also, to accept reciprocal messages from field devices Fieldbus; to maintain current values of parametres of guidance of process in a database of a registers card.

EFFECT: expansion of functionality due to information interchanges maintenance between various networks.
