Area names in Alarm Logging and in the Picture Tree
Area names
in Alarm Logging and in Picture Tree must not contain any spaces at the beginning
or end.
Area names in distributed systems
With distributed systems, the area names in the projects of the various WinCC servers must
be unique in order to ensure correct filtering and display of the messages according to the
area.
Process picture in the plant view: Level 16 is hidden
Level 16 is always hidden when you create a new process picture in SIMATIC Manager in the
plant view or with the WinCC Explorer.
Do not change this setting if you are using PCS 7 ASSET. The hidden level contains an
"@RTBehaviourParams" object that is used for diagnostic purposes.
Image painting time
To optimize the image painting time, set the "WinCC Classic" design in the WinCC project
properties.
User authorization "No. 8 Controlling archives"
User authorization "No. 8 Controlling archives" in User Administrator is no longer used by the
system.
Authorization check in WinCC ServiceMode
There are three possible scenarios for WinCC in ServiceMode that influence the Runtime
behavior due to authorization check:
● No Windows user logged on.
A user is defined as "User in service context" in WinCC User Administrator.
The authorizations of this user in the service context will be checked in Runtime. This setting
will influence the trigger authorization for the signaling device.
● No Windows user logged on.
No user is defined as "User in service context" in WinCC User Administrator.
The signaling device will always be activated in Runtime.
● A Windows user is logged on. Interactive user inputs are possible.
If a user is defined in the service context does not have an effect in Runtime.
The authorizations of the logged on WinCC user will be checked in Runtime.
