This example shows how to connect to an OPC UA server that requires authentication and secure communication. To run the example, the ExampleServer needs to be started with the following arguments:

ExampleServer -cert -ac

Authentication and security can be configured by redeclaring the replaceable models AuthenticationConfiguration and SecurityConfiguration in Client. This is accessible by selecting the client and navigating to the Parameters section of the General view.

Secured communication is enabled by setting SecurityConfiguration to Secured communication configuration. Click the edit button next to the value to edit the security configuration; for more information on configuring communication security, see Secured.

To enable authentication, set AuthenticationConfiguration to the desired authentication method. This example uses Username; for a list of supported authentication methods, see the Authentication package. Click the edit button next to the value to specify method-specific parameters, in this case, username and password.

If secure communication and authentication are successfully established, simulating the example will generate a plot of the node "the.answer", which is initialized to 42 by the ExampleServer.
