• Burst Mode is not supported

There are two ways of using the HART

communication:

• as Point-to-Point connection and
• as Multi-Drop connection with 2-wire connection.

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

Point-to-Point connection between the signal converter and the HART

Master.

The current output of the device is passive.

Also.

9.3.2 Multi-Drop connection (2-wire connection)

Up to 15 devices may be installed in parallel (this signal converter and other HART

devices).

For an illustration of multi-drop networks.

For data on communication in multi-drop mode.

9.4 HART

device variables

The HART® dynamic variables PV (Primary Variable), SV (Secondary Variable), TV (Third Variable)
and 4V (Fourth Variable) can be assigned to any of the device variables.

The HART

dynamic variable PV is always connected to the HART

current output which is, for

example, assigned to level measurement.

9.5 Field Communicator 375/475 (FC 375/475)

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.

9.5.1 Installation

System and software requirements for the Field Communicator

• System card that includes the "Easy Upgrade Option"
• Field Communicator Easy Upgrade Programming Utility

• HART

Device Description file

For more data, refer to the Field Communicator User’s Manual.

CAUTION!
The Field Communicator cannot be used to correctly configure, operate or read data from the
device unless the Device Description (DD) file is installed.
