This OPC Studio service allows management of OPC UA client or server application. The OPC UA Client-Server Application Service has high-level properties and methods for tasks related to maintaining application registrations in the GDS servers, obtaining instance certificate from GDS, refreshing application trust lists from GDS, and similar tasks.

The OPC UA Client-Server Application Service is represented by the IEasyUAClientServerApplication Interface and can be obtained from the EasyUAClient component. It is, however, recommended that you use the common instance of the EasyUAApplication Class instead (see Instance Property). This class implements the IEasyUAClientServerApplication Interface, and the object instance is easier to obtain compared to retrieving the service from the EasyUAClient Class.

For more information about this service, see OPC UA Application.
