Orion Instruments Jupiter 2xx FOUNDATION Fieldbus - Manual (Page 5)

57-649 Jupiter Magnetostrictive Transmitter - F OUNDATION fieldbus™ 5
Details regarding cable specifications, grounding, termination,
and other network information can be found in IEC 61158
or the wiring installation application guide AG-140 at
www.fieldbus.org.
1.2 Benefits
The benefits of F OUNDATION 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. Orion
Instruments Jupiter device registration can be found at
www.fieldbus.org. Choose Magnetrol as the device manu-
facturer when searching for the registration.
2. Operation: With control now taking place within the
devices in the field, better loop performance and control are
the result. A F
OUNDATION fieldbus ™ system allows for mul-
tiple 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.
1.3 Device Configuration
Device Descriptions
The function of a F OUNDATION fieldbus ™ device is deter-
mined by the arrangement of a system of blocks defined by
the Fieldbus Foundation. The types of blocks used in a typi-
cal User Application are described as follows:
Resource Block describes the characteristics of the
F
OUNDATION
fieldbus ™ device such as the device name,
manufacturer, and serial number.
Function Blocks are built into the F
OUNDATION
fieldbus ™
devices as needed to provide the desired control system
behavior. The input and output parameters of function
blocks can be linked over the Fieldbus. There can be
numerous function blocks in a single User Application.
Transducer Blocks contain information such as calibration
parameters and sensor type. They are used to connect the
sensor to the input function blocks.
