8 DESCRIPTION OF HART INTERFACE

SMARTPAT COND 7200

8.1 General description

The open HART^® protocol, which can be used for free, is integrated into the sensor for communication.

Devices which support the HART^® protocol are classified as either operating devices or field devices. When it comes to operating devices (Master), both manual control units (Secondary Master) and PC-supported workstations (Primary Master) are used in, for example, a control center.

HART^® field devices include sensors, signal converters and actuators. The field devices range from 2-wire to intrinsically safe versions for use in hazardous areas.

The HART^® data are superimposed over the analogue 4...20 mA signal via FSK modem. This way, all of the connected devices can communicate digitally with one another via the HART^® protocol while simultaneously transmitting the analogue signals.

When it comes to the field devices and secondary masters, the FSK or HART^® modem is integrated. If a PC is used, an external modem must be connected to the serial interface (USB interface). There are, however, other connection variants which can be seen in the following connection figures.

8.3 Connection variants

The sensor is a 2-wire device with a passive 4...20 mA current output and HART^® interface.

• Multidrop mode is supportedMultidrop mode is supportedMultidrop mode is supportedMultidrop mode is supported

In a multidrop communication system, up to 32 devices can be connected to a common transmission cable.

• Burst mode is not supportedBurst mode is not supportedBurst mode is not supportedBurst mode is not supported

In the burst mode a slave device transfers cyclic pre-defined response telegrams, to get a higher rate of data transfer.

There are two ways of using the HART^® communication:

• as Point-to-Point connection and

• as Multidrop connection, with 2-wire connection.

CAUTION!

For installation in a multidrop communication system please consider the voltage drop for the 250 Ω loop resistance for HART^® communication. The supply voltage has to be adjusted.

SMARTPAT COND 7200

8.3.1 Point-to-Point connection - analogue / digital mode

Point-to-Point connection between the sensor and the HART^® Master.

The current output of the sensor is passive.

8.4 Inputs/outputs and HART ^® dynamic variables and device variables

Code = device variable code

The HART^® dynamic variable PV can be switched between conductivity and resistivity. If the PV is mapped to conductivity, the SV is mapped to resistivity and vice versa.

8.5 Field Communicator 475 (FC 475)

The Field Communicator is a hand terminal from Emerson Process Management that is designed to configure HART^® and Foundation Fieldbus devices. Device Descriptions (DDs) are used to integrate different devices into the Field Communicator.

8.5.1 Installation

The HART^® Device Description for the sensor must be installed on the Field Communicator.

Otherwise only the functions of a generic DD are available to the user and the entire device control is not possible. A "Field Communicator Easy Upgrade Programming Utility" is required to install the DDs on the Field Communicator.

The Field Communicator must be equipped with a system card with "Easy Upgrade Option". For details consult the Field Communicator User’s Manual.

8.6 Field Device Tool / Device Type Manager (FDT/DTM)

A Field Device Tool Container (FDT Container) is basically a PC program used to configure a field device via HART^®. To adapt different devices, the FDT container uses a so-called Device Type Manager (DTM).

8.6.1 Installation

If the DTM for the sensor has not yet been installed on the FDT Container, setup is required and is available for download from the website or on CD-ROM. See the supplied documentation for information on how to install and set up the DTM.
