Table 18-2
Setting Meaning
“Interactive User” The account of the currently logged on user is used.
If, however, no user uses the computer, there is no interactive user
and the COM object cannot be created. If you operate without a
logged on user, use the “This User” setting. “Interactive user” is the
default setting for the OPC Server for SIMATIC NET.
“The Launching User” The account of the user that launched the OPC client is used.
This user must then also have the required permissions; in other
words, must be entered in the “Security” tab. The user must also
have the default permissions entered for the group of users on this
computer; in other words, must belong to the group of users.
This mode must not be used with the OPC server for SIMATIC NET,
since the OPC server would otherwise be started more than once by
different user accounts and this is not permitted.
“This User” The account of a specified user is used. This user must have the
required permissions; in other words, must be entered in the
“Security” tab. The user must also have the default permissions
entered for the group of users on this computer; in other words, must
belong to the group of users.
This setting must be used to operate the OPC server for SIMATIC
NET (logged on users).
S
Multiterminal Mode
You should also use the setting described here “This user” for
multiterminal mode on the PC station.
