HART Communications
Highway Addressable Remote Transducer, HART, is an industrial protocol that is
superimposed on the 4-20 mA signal. It is an open standard, and full details about HART
can be obtained from the HART Communication Foundation at www.hartcomm.org
SITRANS LR 460 can be configured over the HART network using either the HART
Communicator 275 by Fisher-Rosemount, or a software package. There are a number of
different software packages available. The recommended software package is the
SIMATIC Process Device Manager (PDM) by Siemens.
HART Device Description (DD)
In order to configure a HART device, the configurator must have the HART Device
Description for the instrument in question. HART DDs are controlled by the HART
Communication Foundation. Please check with the HART Communication Foundation for
the availability of the HART DD for SITRANS LR 460. Older versions of the library will have
to be updated in order to use all the features of SITRANS LR 460.
SIMATIC Process Device Manager (PDM)
This software package is designed to permit easy configuration, monitoring, and
troubleshooting of HART devices. The HART DD for SITRANS LR 460 was written with
SIMATIC PDM in mind and has been extensively tested with this software.
The Device Description for SIMATIC PDM may be downloaded from the product page of
our website at: https://pia.khe.siemens.com/index.asp?Nr=7427, under Downloads.
All parameters accessible via the HART Communicator are also accessible via PDM. In
