ST100 Series Foundation Fieldbus
Fluid Components International LLC 3
Introduction
This manual describes the ST100 Foundation Fieldbus features, its operation and configuration. The ST100 can provide up to 4 different process vari-
ables. It provides Flow, Temperature, Flow Totalizer and Pressure, as outputs. The flow output can be selected as volumetric, mass or velocity units.
The basic ST100 can support up to two flow sensors providing the average flow of the two sensors in a single output.
Foundation Fieldbus differs from any other communication protocol, because it is designed to resolve process control applications instead of just
transfer data in a digital mode.
This document is written to be used with all members of the ST100 series product line configured with Foundation Fieldbus digital communication
Protocol.
Foundation Fieldbus is provided through an extension card that is fully integrated into the ST100 instrument.
Definition
AI Block: Analog Input Block. This block receives the ST100 Process Data Variables from the Process Data Transducer Block and makes the process
data available for the function blocks.
There are 4 AI blocks in the ST100, these are the Flow AI Block, Temperature AI Block, Totalizer AI Block and the Pressure AI block. Not all Process
Variables are available in every member of the ST100 family.
TB Block: Transducer block. This block makes the connection to the ST100 signal processing hardware of the ST100, presents the process vari-
ables, and facilitates the instrument setup through Foundation Fieldbus.
PID Block: The Proportional, Integral, Derivative, control function block offers a lot of control algorithms that use the Proportional, Integral, and
Derivative Terms. The algorithm of the ST100 PID is the non-iterative, ISA version.
RS Block: The Resource block contains basic FF information about the ST100 and some configuration data.
FF Configurator: Is a software tool used to access data and configure FF devices.
DD Files: The Device Description Files are used by configuration software, like the NI configurator or handheld configurators like the Emerson 475, or
other FF hosts. The DD files describe the FF device, they also allow for custom manufacturer specific features to be added to a FF device, and provide
access to the instruments custom features to the host.
FCI Configurator: A 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 or the Ethernet Service port.
