OPC Watch
Download: https://docs.traeger.de/en/software/sdk/opc-ua/net#download
Usage: Browse, read, write, subscribe nodes or generate code for user defined types from server or nodeset.

Features:
• DA: Data Access
• HDA: Historical Data Access
• AE: Alarms & Events + Conditions
• IO: FileAccess
• API: Methods and Enumerations
• OPC Classic Support
• Others:
 • Units of Measurements
 • Complex/Structured Data Types

Characteristics:
• Simple and fast Client & Server Development
• Minimum number of lines of code
• Uses OPC Foundation Stack v1.03.351.0
• Significantly reduced lines of code compared to OPC Foundation Stack

Framework Features:
• Data Types using Name-Value pairs, .NET dynamic and user defined types
• Linq to Objects support to browse nodes
• Simplified automatic certificate management
• Advanced node identifier formats like compound, URI or Foundation
• Database Cursor like historical data access
• Event driven programming model for certificates and subscriptions

Tested with:
• SIMATIC S7-1500, SIMOTION, SINUMERIC, ...
• and many more other vendors

Works on:
• Windows
• Ubuntu
• Debian
• macOS

Optimized for:
• SIMATIC S7-1500 / S7-1200
• SIMOTION
• SINUMERIC
• all OPC UA Servers from Siemens and other providers

The OPC UA .NET SDK comes with an evaluation license which can be used unlimited for each application run for 30 minutes. If this restriction limits your evaluation options, you can request another evaluation license from us for free. Just ask our support (via support@traeger.de) or let us consult you directly and clarify open questions with our developers!

A snippet to dig into your server:

using Opc.UaFx.Server;
...
var machineNode = new OpcObjectNode("Machine");
var messageNode = new OpcDataVariableNode<string>("Message","Hello World!");

using (var server = new OpcServer(
        "opc.tcp://localhost:4840/", machineNode, messageNode)) {
    server.Start();
    Console.ReadLine();

    // Your further code to interact with the clients.
}

A snippet to dig into your client:

using Opc.UaFx.Client;
...
using (var client = new OpcClient("opc.tcp://localhost:4840/")) {
    client.Connect();
    Console.WriteLine(client.ReadNode("ns=2;s=Message"));

    // Your further code to interact with the server.
}

Let's Define a Node + Read the Node

// ----- Server -----

OpcDataVariableNode<bool> isRunningNode = new OpcDataVariableNode<bool>(
        machineNode,
        "IsRunning",
        value: true);

// ----- Client -----

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

More: Read Values of Node(s)

Let's Define a Node Tree + Write some Nodes

// ----- Server -----

OpcObjectNode jobNode = new OpcObjectNode(
        machineNode,
        "Job",
        new OpcDataVariableNode<bool>("Cancel", false),
        new OpcDataVariableNode<int>("State", -1));

// ----- Client -----

OpcStatusCollection results = client.WriteNodes(
        new OpcWriteNode("ns=2;s=Machine/Job/Cancel", true),
        new OpcWriteNode("ns=2;s=Machine/Job/State", 0));

More: Node Management
More: Write Values of Node(s)

Let's Define + Read a File Node

// ----- Server -----

System.IO.File.WriteAllText("Report.txt", "This is my report.");
OpcFileNode reportNode = new OpcFileNode(machineNode, "Report", "Report.txt");


// ----- Client -----

// 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());
}

Report and Observe some Alarm's and Event's

// ----- Client -----

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

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


// ----- Server -----

server.ReportEvent(OpcEventSeverity.Low, "Finished JOB-4711");

More: Providing Events
More: Working with Events

Report and Observe only Alarm's and Event's from interest

// ----- Server -----

OpcAlarmConditionNode temperatureAlarmNode = new OpcAlarmConditionNode(
        machineNode,
        "Temperature");

temperatureAlarmNode.Severity = OpcEventSeverity.High;
temperatureAlarmNode.Message = "Overheating use cases!";


// ----- Client -----

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);


// ----- Server -----
