PROFIBUS DP Communication Module
SIRIUS 3RW44 manual
8-4 GWA 4NEB 535 2195-02 DS 06
8.1 Introduction
This chapter describes the PROFIBUS DP communication module for the
3RW44 soft starter.
Using the PROFIBUS DP communication module, the 3RW44 soft starter can be
linked to the Profibus branch with all its functionality.
Prerequisites
• You have configured an infeed module with integrated S7 station
e.g. with CPU315-2 DP.
• STEP 7 (V 5.1 and higher + Hotfix 2) is completely installed on your PC/PD.
• You are proficient in STEP 7.
• The PD is connected to the DP master.
Notice
The PROFIBUS DP communication module only works with 3RW44 devices of
product version "E06" or higher, implemented for devices from production date
060501 onwards.
Notice
IT systems with ground fault monitoring:
3RW44, product version *E06* and the PROFIBUS DP communication
module must not be used in this network configuration. 3RW44 soft starters as of
product version *E07* can be used in combination with the PROFIBUS DP
communication module. However, phase voltage values (UL-N) and phase-to-
phase voltage values (UL-L) may be displayed incorrectly on the measured
value display of the 3RW44.
Notice
For 3RW44 PROFIBUS DP communication module, product version *E03*:
Use of the 3RW44 with PROFIBUS for redundant controls and Y link:
The 3RW44 acts like a DPV0 Slave in the Y link. Parameterization can only be
carried out via the GSD file. Only cyclic data is transmitted, no data sets or
alarms.
For 3RW44 PROFIBUS DP communication module from product version *E04*
onwards: From this version onwards, DPV1 operation (read, write data set and
alarms) is also possible downstream from a Y link.
