ST100 Series HART
Fluid Components International LLC 1
Introduction
This manual describes the ST100 HART protocol 7.3 features, its operation and configuration. The ST100 can provide up to 4 different process
variables. It provides Flow, Temperature, Flow Totalizer, and Pressure, as outputs. The flow output can be selected as Volumetric, Mass
or Velocity units. The ST102 and ST112 can support up to two flow sensors and provides the average flow of the two sensors in a single output.
This documents is written to be used with all members of the ST100 product family configured with the HART 7.3 communication Protocol.
The HART output is provided through an extension card that is fully integrated into the ST100 instrument.
Definition
Universal HART Commands
A collection of commands that must be supported by All HART compatible devices. The Universal Command Specification establishes the minimum
Application layer support required of all HART devices. The Application layer defines the commands, responses, data types and status reporting sup-
ported by the Protocol.
Common Practice HART Commands
A collection of commands applicable to a wide range of devices. These commands shall be supported by devices whenever possible. The HART Com-
mon Practice Commands enhances interoperability by providing additional standardized, device-independent commands.
Device Specific Commands
Commands defined by the manufacturer according to the need of the Field device. The manufacturer of the Field device controls these commands.
The FCI ST100 family of products has 20 manufacturer specific commands.
EDDL/DD Files
Text files interpreted by the host system. The EDDL file is a file that tells the host what functionality the device (ST100) has, and how the functionality
is invoked. The EDDL also tells the host to do common maintenance functions such as calibration, configuration check status of individual sensors,
change engineering units, etc.
FCI Configurator
A PC software tool that gives access to the ST100 functions and features. It facilitates basic instrument setup and configuration, as well as advance
functions. The FCI configurator can interface through the ST100 USB Service port on the Ethernet Service port.
