Proxy Control Connection
A Proxy Control Connection aspect is created on the Proxy object for all aspects
that defines OPC properties not marked as “Ignore at upload” in the remote system.

The Proxy Control Connection shows the information for all properties, and can be
used when building faceplates and displays like any other control connection
aspects. It is also possible to subscribe for OPC properties values from this aspect.
It is not possible to make any configuration changes in those aspects. All changes
should be done in the provider system, and uploaded again.
Proxy Log Configuration
A Proxy Log Configuration aspect represents a log configuration in the provider
system. It has the same behavior as a log configuration in the subscriber system, but
it is read-only.
Proxy Log Template
A Proxy Log Template aspect represents a log template in the provider system.

It has the same behavior as a log template in the subscriber system, but it is read-
only.
Miscellaneous Configuration
Security Configuration
Security for the OPC properties in the provider system is controlled by the provider
system only. The domain user or the user mapped in the provider is used to evaluate
the access rights. The major difference between remote user and local user
evaluation of security is that the node used for the evaluation is the node where the
Remote Access Server is running, not the node the user in the subscriber system is
using.
One optimization, to hide the properties in the control programs not necessary to
have as OPC properties, affects the size of the uploaded information.
