Abstract: A reconfigurable interface device for providing access to a plurality of fieldbus networks. The interface device includes a reconfigurable circuit which provides access to a selected fieldbus network from among several optional fieldbus networks. According to an embodiment, the reconfigurable circuit includes a plurality of media units, each media unit providing access to one of the several optional fieldbus networks, and a switch unit coupled to each of the plurality of media units, the switch unit activating a media unit corresponding to the selected fieldbus network, and deactivating remaining media units. A reconfigurable control device is provided for controlling and monitoring a plurality of fieldbus networks. The control device includes a host, having a server and non-volatile memory, and a reconfigurable interface device having a reconfigurable circuit.

Abstract: An interface device for interfacing a computer to a Fieldbus control system thereby allowing the computer to configure, control, and monitor components such as sensors and actuators which are coupled to the Fieldbus. The interface device connects to a serial port of the computer and to a Fieldbus, providing the necessary formatting of data and conditioning of signals exchanged between the Fieldbus and the computer. The interface device is powered entirely or partially from the computer via the serial port and thus does not further load a Fieldbus to which it is connected. The interface device is also portable and is thus well suited for interfacing a portable computer to a Fieldbus system in the control room or the field, e.g., close to the Fieldbus components to be monitored or controlled.
