The TestClient application can be used to check an OPC AE server connection and the events it produces.

Usage: Specify a network machine name as the current node and browse the OPC AE servers on this machine.   Clicking Connect connects to the selected server and displays the server status and the category and conditions definitions.   Click Create Subscription to open a dialog that displays the events reported by the server.

In the default setting no events are filtered.

The filter settings can be changed to display only the events that pass the current filter.
