Communications for the SITRANS LC500
Highway Addressable Remote Transducer (HART) is an industrial protocol that rides on
top of a 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
The SITRANS LC500 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 Descriptor (DD)
In order to configure a HART device, the configurator must have the HART Device
Descriptor for the unit in question. HART DD’s are controlled by the HART
Communications Foundation. The HART DD for the SITRANS LC500 will be released in
2003. Please check availability with the HART Communications Foundation. Older
versions of the library will have to be updated in order to use all the features in the
SITRANS LC500.
Simatic Process Device Manager (PDM)
This software package is designed to permit easy configuration, monitoring, and
troubleshooting of HART and Profibus PA devices. The HART DD for the SITRANS LC500
was written with Simatic PDM in mind and has been extensively tested with this
software.
