Hello.

Do you have an evidence that KepServerEx actually supports OPC UA Alarms&Conditions? I cannot find it listed anywhere. And, I tried approximately the same operation using another OPC client and got BadMonitoredItemFilterUnsupported as well.

Best regards

Hi!

I have some difficult to subscribe alarm and event with Kepware 6 in delphi.
I have created 1 event but it seem that i can't subscribe it.
const
  UAObjectIds_Server = 'nsu=KEPServerEX;ns=2;s=FLOWSERVE.FLOWSERVE.Modbus_List_Overall.MOTOR RUNNING.HI';
var
  Client: TEasyUAClient;
  ClientEventHandlers: TClientEventHandlers18;
  EndpointDescriptor: string;
begin
  EndpointDescriptor := 'opc.tcp://127.0.0.1:49320';
 
  // Instantiate the client object and hook events
  Client := TEasyUAClient.Create(nil);
  ClientEventHandlers := TClientEventHandlers18.Create;
  Client.OnEventNotification := ClientEventHandlers.Client_EventNotification;
 
  WriteLn('Subscribing...');
  Client.SubscribeEvent(EndpointDescriptor, UAObjectIds_Server, 1000);
 
  WriteLn('Processing event notifications for 30 seconds...');
  PumpSleep(30*1000);
 
  WriteLn('Unsubscribing...');
  Client.UnsubscribeAllMonitoredItems;
 
  WriteLn('Waiting for 5 seconds...');
  Sleep(5*1000);
 
  WriteLn('Finished.');
  FreeAndNil(Client);
  FreeAndNil(ClientEventHandlers);

but i got BadMonitoredItemFilterUnsupported.

i have attached my simple alarm and event(You can import it in Kepware alarm&event)
