The OPCUA.Components.Core.Client configures and sets up the connection to an OPC UA server. Any model using the WriteNodeList or ReadNodeList components must be connected to a Core.Client that provides it with the connection to the OPC UA server.

In situations where it is sufficient with a single sample rate for reading and one for writing, it is possible to use the simplified OPCUA.Client that has a built-in WriteNodeList and ReadNodeList.
