7.4 WinCC in the Demo Mode
Reaction to missing license
If a license is missing, WinCC runs in demo mode.
This allows you to operate WinCC for testing and presentation purposes or for local
configuration modifications if only one WinCC RT license is available.
To exit WinCC demo mode, install the required licenses.
Note
When you subsequently transfer a license in the demo mode, it first takes effect when you
restart WinCC.
Even without a license, process mode is fully functional without loss of data for archiving or
alarm logging.
Missing WinCC RC licenses
If WinCC RC licenses are missing, the WinCC Explorer and the editors are terminated after
one hour in demo mode.
You can use the editors and save the changes until demo mode expires.
Missing WinCC RT licenses
If WinCC RT licenses are missing, a message which prompts you to acquire a valid license
and has to be acknowledged is displayed when you start Runtime.
This message is redisplayed every 10 minutes and must be acknowledged. If the message
window is moved, the window reappears again, centered, after 30 minutes at the most.
As long as you are in Runtime, WinCC Explorer is not terminated. On exiting from runtime,
WinCC Explorer is also closed.
Missing licenses for WinCC options
If the license keys for WinCC options in use are missing, WinCC switches to demo mode,
regardless of whether or not other license keys are available.
