Procedure
1. Make sure that the motor is switched o and you do not start the motor during the rmware 
update.
A control command for starting the motor is not supported during the rmware update.
To ensure the quickest and most fault-free rmware update, it is recommended that you 
disconnect the main voltage (operating voltage) of the 3RW5 soft starter and set the 
CPU / PLC to STOP mode.
2. Perform the update of the device rmware.
The following procedures are recommended:
– Via SIRIUS Soft Starter ES (TIA Portal) Premium / Professional on the 3RW5 communication 
module
Brief overview: Window "Project Navigation" with current project under created Soft 
Starter > "Online & Diagnostics" > Window "Work area" > "PROFINET IO ST / 
PROFINET IO HF > Functions > Firmware update"
– Via the conguration software of the controller (e.g. STEP 7 with corresponding HSP) on 
the 3RW5 communication module
Further procedures are possible:
– With a micro SD card via the 3RW5 HMI High Feature (Page 141)
– Via SIRIUS Soft Starter ES (TIA Portal) over the local interface on the 3RW5 HMI High 
Feature
