1. Fieldbus Foundation, Austin, TX (United States)

An all-digital, serial, two-way communications system that interconnects sensors, actuators, and controllers, Foundation fieldbus serves as a local area network (LAN) for instruments used in process and other manufacturing automation applications. The Fieldbus Foundation`s (FF) technology incorporates function blocks that distribute control across the network. Function blocks automatically support alarms, trends, and multiple failure-report levels, without the need for higher-level intervention, and also provide a built-in plant-instrumentation database. Foundation fieldbus will connect individual control devices and may link to a 1.0 Mbit/sec or 2.5 Mbit/sec fieldbus serving as a field communication backbone. It is intended for integrated process-control networks that perform closed-loop continuous control, batch sequencing, recipe management, and data-gathering tasks. The 1.0/2.5 Mbit/sec (H2) bus it also suited for complex logic functions in discrete control networks. 4 figs.
