Abstract

Systems and methods for facilitating communication with Foundation Fieldbus linking devices are described. A plurality of Foundation Fieldbus linking devices may be identified by a gateway device that includes one or more computers. A single virtual address representative of the plurality of linking devices may be determined by the gateway device. Communications between the plurality of linking devices and an external system may the be facilitated by the gateway device, and the virtual address may be utilized to represent the plurality of linking devices to the external system.
