Hart Communication; Mode Of Operation Hart Function - Siemens SITRANS FC330 Operating Instructions Manual

HART communication

Highway Addressable Remote Transducer, HART, is an industrial protocol. The HART protocol
is an open standard. Full details about HART can be obtained from the HART communication
website (https://fieldcommgroup.org/technologies/hart).
The device can be configured over the HART network using either a Field Communicator or a
software package. The recommended software package is the SIMATIC Process Device
Manager (PDM) (Page 123) by Siemens. Use HART Device Description (EDD) to integrate
HART devices in engineering systems as SIMATIC PDM and AMS.
HART Communicator menu structures are available in HART Communication Foundation
(https://fieldcommgroup.org/technologies/hart).

Mode of operation HART function

Note
Priority of operation and failure of power supply
● Operation at the positioner has priority over specifications from the HART communicator.
● Failure of the auxiliary power to the positioner also interrupts communications.
Function
The device is also available with built-in HART functionality. The HART protocol allows you to
communicate with your device using a HART communicator, PC, or programming unit. You can
do the following with your device:
● Convenient configuration
● Store configurations
● Call up diagnostic data
● Show online measured values
Communication takes place as frequency modulation on the existing signal lines for the
setpoint of 4 to 20 mA.
The device is integrated into the following parameter assignment tools:
● HART communicator
● PDM (Process Device Manager)
● AMS (Asset Management System)
