If nothing happens when inserting a SINAMICS drive or incorrect article numbers are displayed for SINAMICS components, you should delete the cache of TIA Portal.

You will experience one of the following scenarios:

  • You add a SINAMICS drive to your project, but it is not displayed.
  • Incorrect article numbers are displayed for at least one SINAMICS component (please compare the article number on the SINAMICS components with the one configured in TIA Portal) and an upload or download from/to the SINAMICS is not possible.

    Example with incorrect article numbers for the SINAMICS G120C 


Delete the cache of the TIA Portal, proceed as follows:

  1. Close the TIA Portal.
  2. Open the Windows Explorer and navigate to the folder "C:\ProgramData\Siemens\Automation\EDD_Component":
  3. Delete the entire contents of the "EDD_Component" folder
  4. Start the TIA Portal again.

  • You can now insert SINAMICS drives again.
  • Possibly you have to reinsert the SINAMICS in order to have correct article numbers again and to be able to carry out uploads and downloads.

  1. In the Windows Explorer you click "View" and select "Options".
