Requirements
• Valid firmware update
You will find the latest firmware files on the 3RW5 topic page (
support.industry.siemens.com/cs/ww/en/view/109747404
).
• For operation of an application in Class I and Class II Hazardous Locations:
DANGER
Loss of the certified motor overload protection according to ATEX/IECEx.
Will cause death or serious injury.
A certified motor overload protection according to ATEX / IECEx is only provided for 3RW55
soft starters from firmware version V2.0 (does not apply to 3RW55 Failsafe soft starters).
Note that it is not permissible to downgrade to a previous firmware version because
otherwise certified motor overload protection according to ATEX / IECEx cannot be
guaranteed.
Procedure
1. Make sure that the motor is switched off and you do not start the motor during the firmware
update.
A control command for starting the motor is not supported during the firmware update.
To ensure the quickest and most fault-free firmware update, it is recommended that you
disconnect the main supply voltage (operational voltage) of the 3RW55 and 3RW55 Failsafe
soft starters and put the CPU / PLC into the STOP state.
2. Perform the update of the device firmware.
The following procedures are possible:
– With a micro SD card via the 3RW5 HMI High Feature (Page 277)
– Via the local interface of the 3RW5 HMI High Feature with SIRIUS Soft Starter ES
(TIA Portal)
Brief overview: Window "Project Navigation" with current project under created Soft
Starter > "Online & Diagnostics" > Window "Work area" > "Soft Starter /
3RW5 communication module used / HMI > Functions > Firmware Update"
– With a fieldbus via a 3RW5 communication module with SIRIUS Soft Starter ES (TIA Portal)
Premium / Professional or the configuration software of the controller (e.g. STEP 7 with
corresponding HSP) (via a 3RW5 PROFINET or PROFIBUS communication module only)
Note
Firmware update of the 3RW5 PROFINET High Feature communication module
The firmware update of the 3RW5 PROFINET High Feature communication module via SIRIUS
Soft Starter ES (TIA Portal) at the local interface or using a micro SD card via the 3RW5 HMI
High Feature can take a very long time in comparison with other options (up to about
60 minutes).
Maintenance and service
