OPC UA Security Settings
The OPC UA server does not support message encryption. OPC UA clients typically have two settings for
security. The first is the security policy and the second in the Message Security Mode. Both of these settings
should be set to None for the OPC UA Server Connection (see screenshot below).

OPC UA Address Space
The OPC UA address space contains information about the server and its application. An OPC UA client browses
the address space to determine server functionality and the controller application variables available from the
server. An example client address space view is displayed below.
