Community.TwinCAT.Mdp 0.2.0-beta

TwinCAT MDP Client

Contains a MDP client implementation for the Beckhoff Device Manager communication protocol based on the TwinCAT.Ads.AdsClient. The Root object is the TwinCAT.MDP.MdpClient to communicate with the Beckhoff Device Manager via ADS. Use TwinCAT.Mdp.Reactive for reactive extensions.

Requirements

.NET 5.0, .NET Core 3.1, .NET Framework 4.61 or .NET Standard 2.0 compatible SDK or later. A TwinCAT 3.1.4024 Build (XAE, XAR or ADS Setup) or alternatively the Beckhoff.TwinCAT.AdsRouterConsole Application on Non-TwinCAT systems to route ADS communication.

TwinCAT Version >= 4024.10

Because the Beckhoff.TwinCAT.Ads Version 5.X uses internal interfaces that are available only from TwinCAT 4024.10 on, an appropriate version must be installed locally. The package doesn't work with older installations. An alternativ approach for some use cases is to use the 'Beckhoff.TwinCAT.Ads.AdsRouterConsole' / 'Beckhoff.TwinCAT.TcpIpRouter' packages to establish your own router.

Systems without TwinCAT Installation

Install the 'Beckhoff.TwinCAT.Ads.AdsRouterConsole' package from Nuget.org:

PS> nuget install Beckhoff.TwinCAT.Ads.AdsRouterConsole

See Beckhoff.TwinCAT.Ads for further documentation.

Usage

MdpClient client = new MdpClient();

client.Connect("192.168.1.244.1.1");

foreach (var module in client.Modules)
{
    Console.WriteLine(module.ToString());
}

var cpuUsage = client.ReadParameter<ushort>(ModuleType.CPU, 1, 2);
var cpuUsageAsync = await client.ReadParameterAsync<ushort>(ModuleType.CPU, 1, 2, CancellationToken.None);
var cpuTemp = client.ReadParameter(ModuleType.CPU, 1, 3, typeof(short));
var cpuTempAsync = await client.ReadParameterAsync(ModuleType.CPU, 1, 3, typeof(short), CancellationToken.None);
var osVersion = client.ReadParameter<uint>(ModuleType.OS, 1, 3);
