In order to obtain or modify the security policy URI string, in the default state (when $(memberUrl equals to false), access OpcLabs.EasyOpc.UA.UACommunicationProfile.SecurityPolicyUriString property of UAEndpointSelectionPolicy.CommunicationProfile property of EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of static $(memberUrl. If you have set $(memberUrl to true, you need to access OpcLabs.EasyOpc.UA.UACommunicationProfile.SecurityPolicyUriString property of UAEndpointSelectionPolicy.CommunicationProfile property of EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of $(memberUrl.
Alternatively, you can override the endpoint selection policy for a specific endpoint by setting it to a non-null value in OpcLabs.EasyOpc.UA.UAEndpointDescriptor.EndpointSelectionPolicy.
