Hello,

please, I need your help with settings after converting project from Automation Studio 4.12 to 6.3

I want to disable the login window after open visualization. I still have not been able to find how to turn it off.

Next issue is with OPC UA variables. Now, when I use account test, I am not able to see values from OPC UA variables and in log visu I get error BadUserAccessDenied. When I use account test2 all is OK.  
I need everytime for everyone to see values of OPC UA variables. It is C50 panel.

Thank you very much in advance for your help.

If I got your point properly, you are looking for property StartUp User.

So use fix user and select user who has proper rights for OPCUA
