MTConnect.NET-HTTP 3.4.2

MTConnect Http REST Clients

These client classes use the Http REST Api that is described in Part 1 : Section 5.4 & Section 8 of the MTConnect Standard.

MTConnectClient

The MTConnectClient class is the primary class to use when wanting to implement the full MTConnect protocol. This class handles an initial Probe request to gather capabilities of the Agent, a Current request to read the initial values, and a Sample request (at the specified Interval) to read successive values.

Class Initialization

Class initialization is straightforward in that specifiying the BaseUrl (the URL of the Agent) is all that is required. Then call the Start() method to start the request sequence.

No Device Name (Get All Devices)

using MTConnect.Clients.Rest;

var baseUrl = "localhost:5006";

var client = new MTConnectClient(baseUrl);
client.Interval = 500;
client.Start();

Get Specific Device by Name

using MTConnect.Clients.Rest;

var deviceName = "OKUMA.Lathe";
var baseUrl = "localhost:5000";

var client = new MTConnectClient(baseUrl, deviceName);
client.Interval = 500;
client.Start();

Handle Probe Received Event

(MTConnectDevices Response Document received from a Probe Request)

var client = new MTConnectClient(baseUrl, deviceName);
client.OnProbeReceived += (sender, document) =>
{
    foreach (var device in document.Devices)
    {
        // Device
        Console.WriteLine(device.Id);

        // DataItems
        foreach (var dataItem in device.DataItems)
        {
            Console.WriteLine(dataItem.Id);
        }

        // Components
        foreach (var component in device.Components)
        {
            Console.WriteLine(component.Id);
        }
    }
};
client.Start();

Handle Current Received Event

(MTConnectStreams Response Document received from a Current Request)

var client = new MTConnectClient(baseUrl, deviceName);
client.OnCurrentReceived += (sender, document) =>
{
    foreach (var deviceStream in document.Streams)
    {
        // DeviceStream
        Console.WriteLine(deviceStream.Name);

        // Component Streams
        foreach (var componentStream in deviceStream.ComponentStreams)
        {
            Console.WriteLine(componentStream.Name);

            // DataItems (Samples, Events, and Conditions)
            foreach (var dataItem in componentStream.DataItems)
            {
                Console.WriteLine(dataItem.DataItemId);
            }
        }
    }
};
client.Start();

Handle Samples Received Event

(MTConnectStreams Response Document received from a Sample Stream)

var client = new MTConnectClient(baseUrl, deviceName);
client.Interval = 500;
client.OnSampleReceived += (sender, document) =>
{
    foreach (var deviceStream in document.Streams)
    {
        // Device
        Console.WriteLine(deviceStream.Name);

        // Component Streams
        foreach (var componentStream in deviceStream.ComponentStreams)
        {
            Console.WriteLine(componentStream.Name);

            // DataItems
            foreach (var dataItem in componentStream.DataItems)
            {
                Console.WriteLine(dataItem.DataItemId);
            }
        }
    }
};
client.Start();

MTConnectProbeClient

The MTConnectProbeClient class is used to send a Probe request and return an MTConenctDevices Response Document.

using MTConnect.Clients.Rest;

var deviceName = "OKUMA.Lathe";
var baseUrl = "localhost:5000";

var client = new MTConnectProbeClient(baseUrl, deviceName);
var document = client.Get();
foreach (var device in document.Devices)
{
    // Device
    Console.WriteLine(device.Id);

    // DataItems
    foreach (var dataItem in device.DataItems)
    {
        Console.WriteLine(dataItem.Id);
    }

    // Components
    foreach (var component in device.Components)
    {
        Console.WriteLine(component.Id);
    }
}

MTConnectCurrentClient

The MTConnectCurrentClient class is used to send a Current request and return an MTConenctStreams Response Document.

using MTConnect.Clients.Rest;

var deviceName = "OKUMA.Lathe";
var baseUrl = "localhost:5006";

var client = new MTConnectCurrentClient(baseUrl, deviceName);
var document = client.Get();
foreach (var deviceStream in document.Streams)
{
    // Device
    Console.WriteLine(deviceStream.Name);

    // Component Streams
    foreach (var componentStream in deviceStream.ComponentStreams)
    {
        Console.WriteLine(componentStream.Name);

        // DataItems
        foreach (var dataItem in componentStream.DataItems)
        {
            Console.WriteLine(dataItem.DataItemId);
        }
    }
}

MTConnectSampleClient

The MTConnectSampleClient class is used to send a Sample request and return an MTConenctStreams Response Document.

using MTConnect.Clients.Rest;

var deviceName = "OKUMA.Lathe";
var baseUrl = "localhost:5006";
var fromSequence = 150;
var toSequence = 250;

var client = new MTConnectSampleClient(baseUrl, deviceName, fromSequence, toSequence);
var document = client.Get();
foreach (var deviceStream in document.Streams)
{
    // Device
    Console.WriteLine(deviceStream.Name);

    // Component Streams
    foreach (var componentStream in deviceStream.ComponentStreams)
    {
        Console.WriteLine(componentStream.Name);

        // DataItems
        foreach (var dataItem in componentStream.DataItems)
        {
            Console.WriteLine(dataItem.DataItemId);
        }
    }
}
