WinCC Installation Notes
1.4 Licenses and Licensing
● WinCC/PerformanceMonitor
● SIMATIC Information Server
Other licenses cannot be cumulated.
Demo Mode
If a license is missing for one or several components, WinCC will run in demo mode. WinCC
also switches to demo mode when the maximum authorized number of process tags or archive
tags is exceeded in a project.
In Demo mode, you can use the WinCC software fully for a maximum of one hour. After this
period, the operation of WinCC violates the license agreements.
After one hour, the WinCC Explorer and the editors will be closed.
In runtime, the system will request the acquisition of a valid license. This dialog will appear
every 10 minutes.
To exit WinCC demo mode, install the required licenses.
Details on demo mode may be found in WinCC Information System under "Licensing".
Microsoft SQL Server 2014
A license is necessary to use the Microsoft SQL Server database. This license is readily
available in a licensed and proper installation of WinCC.
The licensed SQL server installed with WinCC may only be used in connection with WinCC.
Its use for other purposes requires an additional license. These include, e.g.:
● Use for internal databases
● Use in third-party applications
● Use of SQL access mechanisms that are not provided by WinCC
Uninstalling
After uninstalling WinCC, the "WinCC" SQL server instance must also be removed. Select
"Control Panel" > "Software" and then select the "Microsoft SQL Server 2014" item for removal.
Installation of Licenses
You may use the Automation License Manager for installation of licenses. Licenses may be
installed during installation of WinCC or after the fact. You will find the Automation License
Manager in the Windows start menu in the "Siemens Automation" program group. An after-the-
fact installation of a license will take effect upon restart of your computer.
For the installation of licenses, the following requirements must be met:
● The storage medium containing the licenses must not be write protected.
● You can install the RC licenses on a license server for the configuration. You do not have
to install the licenses on the local drive.
● Licenses may only be installed on a non-compressed drive.
