2.8.2 Benefits
The benefits of Fieldbus can be found throughout all phases
of an installation:
1. Design/Installation: Connecting multiple devices to a single
pair of wires means less wire and fewer I/O equipment.
Initial Engineering costs are also reduced because the
Fieldbus Foundation
™ requires interoperability, defined as
“the ability to operate multiple devices in the same system,
regardless of manufacturer, without a loss of functionality.”
All F OUNDATION fieldbus devices must be tested for
interoperability by the Fieldbus Foundation. MAGNETROL
Model 705FF device registration information can be found
at www.fieldbus.org.
2. Operation: With control now taking place within the
devices in the field, better loop performance and control are
the result. A Fieldbus system allows for multiple variables to
be brought back from each device to the control room for
additional trending and reporting.
3. Maintenance: The self-diagnostics residing in the smart
field devices minimizes the need to send maintenance
personnel to the field.
