PROFIBUS PA Communications for the SITRANS
LR 400
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be
obtained from PROFIBUS International at www.profibus.com
The SITRANS LR 400 is a Class A, Profile Version 3.0, PA device. It supports Class 1
Master for Cyclic data exchange, and Class 2 for acyclic services: (See below for details).
The SITRANS LR 400 can be configured using a software package. There are a number of
different software packages available and the SITRANS LR 400 should work well with
any one of them. The recommended software package is the Simatic Process Device
Manager (PDM) by Siemens.

Device Descriptor

In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the
Device Descriptor, which will be included with new versions of PDM. Currently you can
locate the Device Descriptor in Device Catalog, under Level/Echo/Siemens Milltronics.
If you do not see SITRANS LR 400 under Siemens Milltronics, you will need to download
an update file from the SITRANS LR 400 product page on our website:
