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. The non-volatile memory stores firmwares for reconfiguring the reconfigurable circuit in accordance with each of the several optional fieldbus networks.
