WinCC Release Notes
2.3 Notes on WinCC
OPC Historical Data Access
Return value OPC_E_MAXEXCEEDED for archive access using OPC
If the OPC client demands data from more than 2000 values during synchronous or
asynchronous reading, the call is rejected with a return message OPC_E_MAXEXCEEDED.
This limit serves to limit the computer load and duration of the call.
This restriction does not apply if the entire time range is read.
OPC Alarm&Event
Avoid bounding values
Avoid using bounding values when reading historical alarms via the WinCC-OPC-A&E-server.
Otherwise, processing read access requests can take a long time, depending on the size of
the archive.
Filtering messages when using format instructions in the user text block
The OPC source of a message is shown in an user text block. This is user text block 2 with
the default setting.
If you use format instructions in this user text block, you need to use wild cards for the filter
setting.
This ensures correct filtering when the OPC sources are generated dynamically in Runtime.

Notes on WinCC ConfigurationTool and WinCC Archive ConfigurationTool
WinCC ConfigurationTool / WinCC Archive ConfigurationTool: Replacement
As of WinCC V7.3 you import and export the WinCC data via the WinCC Configuration Studio.
To import already existing files from the WinCC Configuration Tool/WinCC Archive
ConfigurationTool into the WinCC Configuration Studio, use the menu command "Import" in
the WinCC Configuration Studio.
In addition to the file name, select the "ConfigTool file (*.xlsx)" or "Archive Config Tool file
(*.xlsx)" entry in the file selection dialog.
If you have configured the colors of message types in the WinCC Configuration Tool, the colors
are not imported into the WinCC Configuration Studio from the Configuration Tool. You either
need to create the message colors in the WinCC project before migrating the WinCC project
to WinCC V7.3 and higher or, alternatively, manually configure the message colors later after
the import in the WinCC Configuration Studio.
