Hi Guys

i am trying to download my project from ES to OS, while downloading after copying I am getting a message “Project could not be opened, Data base context doesn’t exist,Invalid”

plz find the attached PM diagnostic file for ref

Hi TNSudheer,

Below I attach the basic requirements for successful ES-OS download:

What are the requirements for operating SIMATIC WinCC in a Windows network?

What should you watch out for when downloading from the WinCC/PCS 7 Engineering Station to the Operator Station (ES-OS download)?

The crucial information, however, is: same Windows users or known Windows users between the ES and OS. The ES Windows user must be known on the OS and vice versa. The same applies to users for operation in server-client environments.
