Getting Started

The whole client development guides can be found here:

The most essential snippet to dig in:

using Opc.UaFx.Client;
...
using (var client = new OpcClient("opc.tcp://localhost:4840/")) {
    client.Connect();
    // Your code to interact with the server.
}

Let's Read a Node

OpcValue isRunning = client.ReadNode("ns=2;s=Machine/IsRunning");

More: Read Values of Node(s)

Let's Write a Node

OpcStatus result = client.WriteNode("ns=2;s=Machine/Job/Cancel", true);

More: Write Values of Node(s)

Let's Read a File Node

// All at once
string reportText = OpcFile.ReadAllText(client, "ns=2;s=Machine/Report");

// All via a stream
using (var stream = OpcFile.OpenRead(client, "ns=2;s=Machine/Report")) {
    var reader = new StreamReader(stream);

    while (!reader.EndOfStream)
        Console.WriteLine(reader.ReadLine());
}

Browse the Node Tree

// One node
OpcNodeInfo machineNode = client.BrowseNode("ns=2;s=Machine");

// A child node
OpcNodeInfo jobNode = machineNode.Child("Job");

// Some child nodes
foreach (var childNode in machineNode.Children()) {
    // Your code to operate on each child node.
}

// Some node attributes
OpcAttributeInfo displayName = machineNode.Attribute(OpcAttribute.DisplayName);

foreach (var attribute in machineNode.Attributes()) {
    // Your code to operate on each attribute.
}

Observe some Alarm's and Event's

client.SubscribeEvent(OpcObjectTypes.Server, HandleGlobalEvents);

...

private static void HandleGlobalEvents(object sender, OpcEventReceivedEventArgs e)
{
    Console.WriteLine(e.Event.Message);
}

More: Working with Events

Observe only Alarm's and Event's from interest

var severity = new OpcSimpleAttributeOperand(OpcEventTypes.Event, "Severity");
var conditionName = new OpcSimpleAttributeOperand(OpcEventTypes.Condition, "ConditionName");

var filter = OpcFilter.Using(client)
        .FromEvents(OpcEventTypes.AlarmCondition)
        .Where(severity > OpcEventSeverity.Medium & conditionName.Like("Temperature"))
        .Select();

client.SubscribeEvent(OpcObjectTypes.Server, filter, HandleGlobalEvents);
