Echelon LNS DDE Server - Manual (Page 48)

The LNS DDE Server has three licensing modes. The first is Temporary Mode. If
there is no license installed on a PC, a Temporary Mode license is generated when
the LNS DDE Server is first started. In Temporary Mode the LNS DDE Server will
run on an otherwise unlimited basis for 30 days. You must acquire an application key
as described in Register Application Key later in this chapter to continue to use the
LNS DDE Server after the Temporary Mode license expires.
The second licensing mode is Demo Mode. In Demo Mode the LNS DDE Server will
operate for approximately one hour at a time. You will be able to restart the LNS
DDE Server when using Demo Mode, but you must close the LNS DDE Server
application and restart it every hour. The LNS DDE Server will operate in Demo
mode when the Temporary Mode license expires.
The third licensing mode is Unlimited Mode. In Unlimited Mode the LNS
DDE Server will operate continuously without interruption. You must
acquire an application key as described in Register Application Key to
enable Unlimited Mode.
