9. Configuration Database
This appendix defines and describes the parameters in the configu-
ration database shown in the following table.
In the following a number in braces {#} indicates the maximum string
length for alphanumeric parameters.
9.1. Flowtube Parameters
• Model Code (MSCode) [alphanumeric entry, {16}]
This is a manufacturer defined quantity. It resides on the VFM 3100
tag and in the database if the electronics and flowtube are shipped
as a unit.
Default: ‘blank’, if electronic module is shipped alone
• Meter Body Serial Number [alphanumeric entry, {16}]
This is a manufacturer defined quantity. It resides on the VFM 3100
tag and in the database, if the electronics and flowtube are shipped
as a unit.
Default: ‘blank’, if electronic module is shipped alone
• Reference K-Factor [numeric entry]
This is the reference calibration factor. It is entered as a pure number.
The value of the number is sufficient to define the proper units, i.e.,
pulses/ft
3 or pulses/liter. It resides on the VFM 3100 tag and in the
database, if the electronics and flowtube are shipped as a unit.
Default: ‘blank’ if electronic module is shipped alone
9.2. Identification Parameters
Tag [alphanumeric entry, {8}]
This is a user defined quantity.
Default: ‘blank’
Descriptor [alphanumeric entry, {16}]
This is a user defined quantity.
Default: ‘blank’
Date [numeric entry, {6}]
This is a user defined quantity. In the case of the HART Configurator
the Date (XXXXXX) is expressed as MMDDYY, for the Local Configu-
rator it is express as YYMMDD.
Default: HART = 051194, Local = 940511
Message [alphanumeric entry, {32}]
Default: ‘blank’
Polling Address [numeric entry, {2}]
This is a user defined quantity. The HART protocol allows the
connections of up to 15 HART devices on a single twisted pair of wi-
res, or over leased telephone lines, a concept known as ‘multidrop-
ping’. In a multidrop installation, each transmitter is identified by a
unique address (1-15) referred to as the polling address. In the multi-
drop mode, i.e., a non-zero polling address, the analog output of the
transmitter is set to a fixed value of 4 mA. For a non-multidrop instal-
lation, i.e., a single transmitter loop, the polling address of the trans-
mitter must be set to zero if the analog output is intended to indicate
flow (4-20 mA).
Default: 0
