Specifications and reference data

A.2.9 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.

A.2.10 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.

A.2.11 FOUNDATION fieldbus Diagnostics Suite (Option Code D01)

The 3051C FOUNDATION fieldbus Diagnostics provide Abnormal Situation Prevention (ASP)

indictation. The integral statistical process monitoring (SPM) technology calculates the mean

and standard deviation of the process variable 22 times per second. The 3051C ASP algorithm

uses these values and highly flexible configuration options for customization to many

user-defined or application specific abnormal situations. The detection of plugged impulse lines

is the first available predefined application.

A.2.12 Low Power (output code M)

Output

Three wire 1–5 Vdc or 0.8–3.2 Vdc (Option Code C2) user-selectable output. Also user

selectable for linear or square root output configuration. Digital process variable superimposed

on voltage signal, available to any host conforming to the HART protocol. Low-power

transmitter operates on 6–14 Vdc with no load.

Power Consumption

3.0 mA, 18–36 mW
