2.3.2 WinCC CS
General information
Using several WinCC editors
Do not
use multiple WinCC editors at the same time because the editors can access the same
WinCC components. For example, use of the "Text Distributor" and "Cross Reference" editors
or automatic update of the Cross Reference when the Graphics Designer is being accessed
simultaneously via interfaces.
If you would like to work in several WinCC editors in parallel, activate the function "Multi-User-
Engineering" in the WinCC project.

Custom ActiveX controls (SIMATIC WinCC/ODK)
You must verify compatibility of custom ActiveX controls (SIMATIC WinCC/ODK) with the
WinCC Basic System, WebNavigator Server, and WebNavigator Client. This applies to both
a direct installation of ActiveX control on the computer with WinCC, Web server or Web client
and the installation using a plug-in, such as on a Web client.
● With a direct installation, the ActiveX control should therefore be installed prior to WinCC
Basic System, Web Server or Web Client. If the custom ActiveX controls do not function
without error after this step, there is no compatibility.
● If the custom ActiveX Control was packaged in a plug-in and installed via download, an
upgrade of WinCC Basic System, Web Server or Web Client will also require generation
of a new plug-in using this ActiveX Control. When creating the plug-in, care should be taken
to use compatible binaries (DLL, OCX, etc.).
The "Date/Time" data format is not available for I/O fields copied from WinCC < V7.3
When you copy an I/O field created in WinCC < V7.3, the "Date/Time" data format is not
available for the pasted I/O field.
Pictures with transparent areas: Using file formats with alpha channel
If you want to use a graphic for Direct2D display which contains transparent areas, use only
graphic formats with an alpha channel, e.g. BMP or PNG.
Information on VBA
VBA updates
The user is solely responsible for the installation of updates for VBA.
