Hello dear all, 

I need to know that can i create a password (for os clients) that be different from es and os servers? How can I do that?

I utilize win7 for es and os clients, and win server2008r2 for os servers, with pcs7 v8.1

Regards

Tekabi

Tekabi-
Yes you can do this.  You'll need to have the same accounts existing on both PC's for file sharing purposes, however the actively logged in account does not need to be the same.

Example:  (example is complaint with domain integration and SIMATIC Logon groups created as another layer on top if needed)

ES/OS/Clients all get the following local accounts and all passwords match on all machines:

Administrator - Admin - only used for installing software/maintenance
SrvServer - User - Service account for ES/OS to auto-login to Windows - needs SIMATIC security groups typical to PCS7
SrvClient - User - Service account for OC to auto-login to Windows - needs SIMATIC security groups typical to PCS7

Since the SrvClient and SrvServer accounts are on both machines, file sharing is fine.  Since SrvClient is a User type account, it is safe for your operators to not be able to mess with the machine too much if they can get past WinCC to the desktop.
