Fault in the connection between the server and the client
If the computer is simultaneously used as a server with the Engineering System and a client
cannot establish the connection to the server, you should check the releases set on the
server.
1. Exit Runtime on the server.
2. Select the command "Find computer..." in the shortcut menu of the network environment
on the desktop of the server.
3. Enter the name of the server as the computer to be found.
4. Open the computer found to recognise the released directories.
5. Remove all the releases that begin with "WinCC_Project_HMI". Information on this is
available in the documentation for the operating system.
This malfunction is caused by the use of the command "Save as..." in conjunction with the
startup of the Runtime of this new project. You can make copies of the projects for backup
purposes using the "Save as..." command. You should, however, continue to work with the
original project.
Language setting for Runtime Professional
With Runtime Professional, illegible texts may occur during runtime if the settings in the
operating system for "Language for non-Unicode programs" do not match the selected
Runtime language. This setting must also be the same on the client and the server for
client/server applications.
Therefore, first check in the Control Panel under "Regional and Language Options >
Advanced" whether the setting for "Language for non-Unicode programs" is the same as the
Runtime language.
Starting WinCC Runtime Professional
If Engineering System and Runtime are operated on a computer, Runtime or simulation for a
project opened in the engineering system should only be started and ended via the TIA
portal. Other options, for example, the symbol in the taskbar information area, should not be
used.
