Appendix B: HART communications
B
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 website:
HART Communication Foundation (http://www.hartcomm.org/
)
The radar device can be configured over the HART network using either the HART
Communicator 375 by Fisher-Rosemount, or a software package. The recommended software
package is the SIMATIC Process Device Manager (PDM) by Siemens.
B.1
SIMATIC PDM
This software package is designed to permit easy configuration, monitoring, and troubleshooting
of HART devices. The HART EDD for this device was written with SIMATIC PDM in mind and
has been extensively tested with this software. For more information, see Operating via
SIMATIC PDM (Page 61).
B.2
HART Electronic Device Description (EDD)
In order to configure a HART device, the configuration software requires the HART Electronic
Device Description for the instrument in question.
You can download the HART EDD for this device from our website:
Product page (http://www.siemens.com/LR250
)

Support>Software Downloads.
Older versions of the library will have to be updated in
order to use all the features of this device.
B.3
HART Handheld 375/475
If the SITRANS LR250 HART device revision is higher than revision 2, the FC375 will report that
the Device Description is not installed and will ask whether you wish to proceed in forward
compatibility mode. It is recommended to choose YES in order to use revision 3 with the FC375.
