Appendix F: Communications via
PROFIBUS PA
SITRANS LR560 (PROFIBUS PA) is a Profile Version 3.01, Class B, PA device. It supports
Class 1 Master for cyclic and acyclic data exchange, and Class 2 for acyclic services.
The full range of SITRANS LR560 functions is available only over a PROFIBUS PA
network.
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be
obtained from PROFIBUS International at www.profibus.com.

Device Configuration tool

To use PROFIBUS PA, you will need a PC configuration tool: we recommend
SIMATIC PDM. Please consult the operating instructions or online help for details on
using SIMATIC PDM. (You can find more information at www.fielddevices.com: go to
Products and Solutions > Products and Systems > Communications and Software >
Process Device Manager.)

SIMATIC PDM

SIMATIC PDM is a software package used to commission and maintain SITRANS LR560
and other process devices. For more detail see
Electronic Device Description
In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the
Electronic Device Description for SITRANS LR560. For details see
Description (EDD)

Network Configuration

To configure a PROFIBUS PA Class 1 Master (for example, a PLC), you will need a GSD
file.

The GSD file

The GSD file SIEM816B.gsd is available from the SITRANS LR560 product page on our
web site at www.siemens.com/LR560. Go to Support > Software Downloads.

Bus Termination

Note:
PROFIBUS PA MUST be terminated at both extreme ends of the cable for it to
work properly. Please refer to the PROFIBUS PA User and Installation Guidelines (order
number 2.092), available from www.profibus.com.

Power Demands

To determine how many devices can be connected to a bus line, calculate the combined
maximum current consumption of all the connected devices: 13.5 mA for SITRANS LR560.
Allow a current reserve for safety.
