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.

Denition

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 or the Ethernet Service port.

Installation

General

For details on the general mounting, placement of sensor head and mounting options see the Basic User Manual, 06EN003400.

Electrical Wiring

Access the wiring terminal block by removing the rear electrical connection cover. This cover can be locked closed by the cover locking screw.

Release the cover locking screw and remove the cover.

Cable access to wiring connections is obtained through one of the four conduit outlets, see Figure 6 below.

Figure 1 - HART Output Wiring Table

The HART connections for the ST100 are located in the back panel. The connector for the HART is P1A; the pins are labeled “CH1” and “RTN 1/2”.

The ST100 HART connections are non- polarized, but polarity needs to be observed for other manufacturer’s devices. Connect the HART bus cable as

noted below. See Appendix A for Channel 1 HART Connections on instruments shippped before April 2012.

Topology and Network Conﬁguration

The ST100 supports Multidrop topology. In multidrop operation, the devices exchange data and measured values only via the HART protocol/HART

Network. In Network conﬁguration the analog current signal serves just to energize the two-wire devices, providing a current of 4 mA per instrument.

In multidrop mode, up to 15 ﬁeld devices are connected in parallel to a single wire pair or segment (Figure 4). The host distinguishes the ﬁeld devices

by their preset addresses that range from 1 to 255. The factory preset address is 0.

Operation

Functional Description

The primary function of the HART protocol is to present the instruments process data through its process data commands. Command 1, command 3

and command 9.

The ST100 does not implement the HART Burst mode. A HART master that supports HART 7.0 and higher is required. A HART communicator that

supports HART 7.0 and higher is required (e.g., Emerson 475 Communicator.)

Process Data Operation

Even though HART 7.0 is compatible with older versions of the HART protocol, the ST100 HART implementation and commands 1 and 3 are still sup-

ported, they contain the Flow Variable only, for the full set of Dynamic variables it is recommended that the HART master use command 9 to request

process data of dynamic variables and status.

ST100 HART Process Data Organization

It is important to brieﬂy review how the ST100 Process data is organized under the HART command 9. For Details on Command 9 see the HART

Speciﬁcation “Universal Commands Speciﬁcation” HCF_SPEC-127, Revision 7.1.

Not all the variables described in this section are available in all conﬁgurations of the ST100 ﬂow meter. For example not all conﬁgurations have

Process Pressure, and instruments that output Mass Flow or Volumetric ﬂow, the Flow Totalizer may be turned on or off.

The following are the ST100 process variables that are provided through HART command 9.

There are 3 ﬂow classes or types, and these are “Exclusively OR” meaning that only one class of ﬂow is active at a time.

PROCESS VARIABLE SLOT # HART VARIABLE CODE

DESCRIPTION DEVICE VARIABLE CODE DEVICE VARIABLE

CLASSIFICATION

VOLUMETRIC FLOW * 0 PRIMARY VARIABLE 0 66

MASS FLOW * 2 PRIMARY VARIABLE 2 72

VELOCITY FLOW * 4 PRIMARY VARIABLE 4 67

VOLUME (TOTALIZER) 1 SECONDARY VARIABLE 1 68

MASS (TOTALIZER) 3 SECONDARY VARIABLE 3 71

TEMPERATURE 5 TERTIARY VARIABLE 5 64

PRESSURE 6 QUATERNARY VARIABLE 6 65

* Implies an “Exclusive OR” Releationship

Under the “Device Variable Status” parameter, for each process variable, only the four most signiﬁcant bits are used.

The two most signiﬁcant bits contain

“Process Data Status”: 11 = good

01 = Poor Accuracy

10 = manual/ﬁxed

00 = bad

The two bits after the two most signiﬁcant contain

“Limit Status”: 11 = constant

01 = low limited

10 = high limited

00 = not limited

Device variable status example: 1100XXXX.X, variable values indicated in positions represented by an ‘X’ can be ignored.

Device Description Files

EDDL Files

TThe ST100 EDDL ﬁles are support ﬁles that provide an extended description of each object in the Virtual Field Device (VFD), and provide information

needed for a control system or host to understand the meaning of the data in the VFD including the human interface. The EDDL ﬁle can be thought as

a “driver” for the device.

FCI provides two types of ﬁles; ﬁrst the standard EDDL ﬁles located in the folder A67F0101, and the Emerson 375 and 475 ﬁles located in the folder

DDP.

A67F0101Folder:

0101.fm8

A67F0101.ddl

DDP Folder:

00A67F0101.hdd

00A67F0101.hhd

0101.fm8

A67F0101.ddl

Loading the DD Files to the 475 Field Communicator

In order to load the DDPs into the Field Communicator the “Easy Upgrade Utility from EMERSON must be used. Below is the procedure for how to

load DD ﬁles into the 475-Field communicator.

Open Field Communicator Easy Upgrade Utility program and click Utilities on the left hand menu; select Import DDs from local source. The following

window should pop up:

Select the FCI ﬁles and press “OK”.
