| Unlike proprietary network
protocols, FOUNDATION fieldbus is neither owned by any individual
company, or regulated by a single nation or standards body. The technology
is controlled by the Fieldbus Foundation, a not-for-profit organization
consisting of more than 100 of the world's leading controls and
instrumentation suppliers and end users. |

| FOUNDATION Fieldbus
is an all digital, serial, two-way communication system that interconnects
devices in the field such as sensors, actuators, and controllers.
FOUNDATION Fieldbus is a Local Area Network (LAN) for instruments, with
built-in capability to distribute a control application across the
network. The benefits of fieldbus
span the life cycle of a plant, from planning and installation through
ongoing operations and maintenance. Interoperability is an added bonus.
The definition of interoperability is "the ability to operate
multiple devices, independent of manufacturer, in the same system, without
loss of minimum functionality." |
| Fieldbus allows many devices
to connect to a single pair of wires. This means less wire, fewer
intrinsic safety barriers, and fewer marshaling panels so your
installation costs are reduced. Connecting multiple field devices to a
single bus also means reduced I/O and control equipment needed, including
card files, cabinets, and power supplies. |
 |
|
| Engineering and
commissioning costs are also reduced because FOUNDATION™
fieldbus function blocks are quickly and easily linked to build a complete
control strategy -- entirely at the field device level. |
| The consistent block-oriented
design of function blocks allows distribution of functions in field
devices from different manufacturers in an integrated and seamless
fashion. |
