Specifications and Reference Data
FOUNDATION Fieldbus
Power supply
External power supply required; transmitters operate on
9.0 to 32.0 Vdc transmitter terminal voltage.
Current draw
17.5 mA for all configurations (including LCD display
option)
F
OUNDATION Fieldbus Parameters
Standard function blocks
Resource block
 Contains hardware, electronics, and diagnostic
information.
Transducer block
 Contains actual sensor measurement data including
the sensor diagnostics and the ability to trim the
pressure sensor or recall factory defaults.
LCD block
Configures the local display.
2 Analog input blocks
 Processes the measurements for input into other
function blocks. The output value is in engineering or
custom units and contains a status indicating
measurement quality.
PID block with auto-tune
 Contains all logic to perform PID control in the field
including cascade and feedforward. Auto-tune
capability allows for superior tuning for optimized
control performance.
Backup Link Active Scheduler (LAS)
The transmitter can function as a Link Active Scheduler if
the current link master device fails or is removed from the
segment.
Software upgrade in the field
Software for the 3051SF with F
OUNDATION Fieldbus is easy
to upgrade in the field using the F
OUNDATION Fieldbus
Common Device Software Download procedure.
PlantWeb alerts
Enable the full power of the PlantWeb digital architecture
by diagnosing instrumentation issues, communicating
advisory, maintenance, and failure details, and
recommending a solution.
Advanced control function block suite
(option code A01)
Input selector block
 Selects between inputs and generates an output using
specific selection strategies such as minimum,
maximum, midpoint, average, or first “good.”
Arithmetic block
 Provides pre-defined application-based equations
including flow with partial density compensation,
electronic remote seals, hydrostatic tank gauging,
ratio control, and others.
Signal characterizer block
 Characterizes or approximates any function that
defines an input/output relationship by configuring up
to twenty X, Y coordinates. The block interpolates an
output value for a given input value using the curve
defined by the configured coordinates.
Integrator block
 Compares the integrated or accumulated value from
one or two variables to pre-trip and trip limits and
generates discrete output signals when the limits are
reached. This block is useful for calculating total flow,
total mass, or volume over time.
Output splitter block
 Splits the output of one PID or other control block so
that the PID will control two valves or other actuators.
 Control Selector Block
 Selects one of up to three inputs (highest, middle, or
lowest) that are normally connected to the outputs of
PID or other control function blocks.
Schedule Entries 14 (max.)
Links 30 (max.)
Virtual Communications Relationships (VCR) 20 (max.)
