After disabling security I've managed to connect. I could not confirm yet,
if encrypted communications works as expected.
My connection string is
`opcua:tcp://DESKTOP-OM18VQ9:4841?discovery=true&security-policy=NONE&message-security=NONE`.
I've used simulated OPC tag called `Address Space.Dev00.Tag000`.
Test code:
```
try (PlcConnection connection = new
DefaultPlcDriverManager().getConnection("opcua:tcp://DESKTOP-OM18VQ9:4841?discovery=true&security-policy=NONE&message-security=NONE"))
{
CompletableFuture<? extends PlcSubscriptionResponse> future =
connection.subscriptionRequestBuilder()
.addChangeOfStateTagAddress("c", "ns=4;s=Address
Space.Dev00.Tag000")
.build().execute();
future.whenComplete((r, e) -> {
if (e != null) {
e.printStackTrace();
return;
}
r.getSubscriptionHandle("c").register(event -> {
for (String field : event.getTagNames()) {
System.out.println("Received state update: " + field
+ " " + event.getObject(field) + " " + event.getResponseCode(field));
}
});
}).get();
Thread.sleep(600_000);
System.out.println("Closing connection");
} catch (PlcConnectionException e) {
throw new PlcRuntimeException(e);
} catch (Exception e) {
e.printStackTrace();
}
```
