Abstract
An interface module is operatively coupled to a Fieldbus process control network and a Modbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a register map database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to register numbers of the Modbus process control network. Once the Fieldbus process control parameters are mapped to the Modbus registers, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the register map database.
