Restriction on enabling UMAC (User Management and Access Control) protection in Startdrive V15.1 and V15.1 UPD1
You have a TIA Portal project which contains with Startdrive added SINAMICS G110M, G120, G120C, G120D and/or G120P drives inside group folders. (Not affected are CU320-2 based drives: SINAMICS S120, G130, G150, S150, S210 und MV)
If you enable UMAC protection (User Management and Access Control) for such a project, the project becomes unusable due to a defect in Startdrive V15.1 (with or without UPD1).
Impacts of the defect is observed only when you re-open the project after enabling UMAC protection.
Only this product releases in combination with SINAMICS G drives are affected:
- Startdrive V15.1
- Startdrive V15.1 UPD1
The defect is fixed in Startdrive V15.1 UPD2 release.
With Startdrive V15.1 UPD2, or newer, the UMAC protection can be enabled without any restrictions
Note: The projects already affected by the defect can not be repaired/recovered using Startdrive V15.1 UPD2.
