Soft Starter ES V15.1 (TIA Portal)

  • Entry
  • Associated product(s)
Soft Starter ES V15.1 is the central software for configuration, commissioning, operation and diagnostics of the SIRIUS 3RW55, 3RW52 and 3RW44 soft starters.
Soft Starter ES V14 / V15 licenses can also be used for Soft Starter ES V15.1. 

Soft Starter ES V15.1 and Soft Starter ES V15 have identical article numbers.

Soft Starter ES V15.1 is integrated seamlessly when further TIA Portal V15.1 based software such as STEP 7 or WinCC is available, thus enabling users to achieve a consistent, efficient and intuitive solution for all automation tasks. 
But those who use Soft Starter ES V15.1 as standalone software will also benefit from its advantages.

Soft Starter ES V15.1 can be installed in parallel to Soft Starter ES V15. 

What's new in Soft Starter ES V15.1 compared to Soft Starter ES V15 Update 2?

The following new features are available for Soft Starter ES in the TIA Portal:

  • Support for the SIRIUS 3RW52 V1.1 soft starters
    • Configuration of the starters  
    • Reading out and printing parameters via the PROFIBUS communication module, the PROFINET Standard communication module or the local device interface of the HMI High Feature
    • Controlling and monitoring via the control panel  
    • Extended diagnostics: Events, logbooks, measured values and statistical data
    • Functions: Commands, factory setting 
  • Changed values are now marked in the expert list by an edit symbol
  • Improvements for "bulk engineering":
    • Copying changed parameters to other devices/groups  
    • Adding a device to multiple groups  
  • Migration of Soft Starter ES 2007 template files (*.sdt) is now possible. Parameters that are marked in Soft Starter ES 2007 as "template" are designated in the expert list as a "favorite" after migration.

Three versions are offered: 

  • SIRIUS Soft Starter ES V15.1 Basic 
    for direct connection to the SIRIUS 3RW44 / 3RW52 / 3RW55 frame size 1-4 (3RW551* - 3RW554*) soft starter via the system interface on the device, for commissioning and parameterization
    New: Since V15, Soft Starter ES Basic as a powerful tool for commissioning or maintenance engineers is offered for download free of charge at Siemens Industry Online Support using this download entry-ID.

  • SIRIUS Soft Starter ES V15.1 Standard 
    for direct connection to the SIRIUS 3RW44 / 3RW52 / 3RW55 frame size 1-4 (3RW551* - 3RW554*) soft starter via the system interface on the device, for commissioning, parameterization and diagnostics with full functionality. 

  • SIRIUS Soft Starter ES V15.1 Premium 
    for connection to one or several SIRIUS 3RW44 / 3RW52 / 3RW55 frame size 1-4 (3RW551* - 3RW554*) soft starters via PROFIBUS DP, PROFINET or directly on the device via the system interface, for commissioning, parameterization and diagnostics with full functionality.

    With Soft Starter ES V15.1 Premium, the soft starters are optionally either parameterized and diagnosed directly on the device or centrally via PROFIBUS DP or PROFINET. Thanks to the display of all operating, service and diagnostics data, Soft Starter ES V15.1 Premium provides valuable information, helps to prevent faults and, in actual fault cases, facilitates fast localization and rectification. 


The software (SW) comprises a trial license. The licensee is granted the non-exclusive, non-transferable right to install the SW on one (1) device and use it for validation purposes.
The period of use is restricted to 21 days, commencing upon initial call-up of the SW.
Siemens can, however, only be held liable for SW for which a trial license is provided or which is provided for validation purposes if Siemens fraudulently conceals any defects.
The license can only be obtained together with a SIRIUS Soft Starter ES V15.1 version subject to costs.
