Alarm and Condition with 2.1.1

Hey andrew I’m a bit lost 😦. I’m trying to program an Client which can read all alarms from an OPC-UA Server. The NodeId is the right one because with UAExpert and the .Net-Legacy-Sample Client I get what I want. the following code snippet is what i tryed but i’m a bit stuck. I’m not sure what to put in the brackets after the token call.

` Console.WriteLine(“Step 5 - Add items to the subscription.”); var alarmitemsToCreate = new MonitoredItemCreateRequest[] { new MonitoredItemCreateRequest { ItemToMonitor = new ReadValueId { NodeId = NodeId.Parse(“…”), AttributeId = AttributeIds.EventNotifier }, MonitoringMode = MonitoringMode.Reporting, RequestedParameters = new MonitoringParameters { ClientHandle = 00001, SamplingInterval = -1, QueueSize = 0, DiscardOldest = true } }, };

            var itemsRequest = new CreateMonitoredItemsRequest
            {
                SubscriptionId = id,
                ItemsToCreate = alarmitemsToCreate,
            };

            var itemsResponse = await Channel.CreateMonitoredItemsAsync(itemsRequest);

           Console.WriteLine("Step 6 - Subscribe to PublishResponse stream.");
            token = Channel.Where(pr => pr.SubscriptionId == id).Subscribe(pr =>
            {???}

});

        }
             `

can you help me ? Is my attempt right or is it already wrong?

@awcullen I really appreciate your work and I want to contribute back to the repository by adding basic samples for using siemens/sinumerik machines. This could help first timers save lot of bucks.

Hi HarishLinkEZ, @rebj1011 seems to say that there was an error in the EventHelper.Deserialize function below:

        foreach (var efl in enl.Events)
        {
            var ev = EventHelper.Deserialize<BaseEvent>(efl.EventFields);
            Console.WriteLine($"time: {ev.Time}, src: {ev.SourceName}, msg: {ev.Message}, sev: {ev.Severity}");
        }

Instead you can try:

        foreach (var efl in enl.Events)
        {
            Console.WriteLine(string.Join(", ", efl.EventFields.Select(e => e.GetValue())));
        }
