Description

The package 'Beckhoff.TwinCAT.Ads.TcpRouter' implements a lean TCP ADS Router class to use on systems where no standard TwinCAT router is established or available.

It is running in UserMode only (no realtime characteristics) and contains no further functionality than distributing the ADS Frames (e.g. no Port 10000, no ADS Secure). It is just used to route ADS frames locally between AdsServers and to/from remote ADS devices.

Implemented in asynchronous .NET Code it can be run in your own services/daemon, as standalone console application and also in your customized application.

Requirements

  • .NET 5.0, .NET Core 3.1, .NET Framework 4.61 or .NET Standard 2.0 compatible SDK or later
  • No other System allocating the same port (e.g. a regular TwinCAT installation)
  • Installed Nuget package manager or Dotnet CLI

Installation

Along with the deployment of the application where the TcpRouter is implemented, a valid Router / ADS configuration must be placed to specify the Local Net ID, the name and the default port of the Router system.

The preferred way to configure the system is with standard Configuration providers, which are part of the .NET Core / ASP .NET Core infrastructure.

See further information: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-3.1

This enables common options for application configuration that can be used 'out-of-the-box':

  • Via the file appsettings.json
  • With the StaticRoutesConfigurationProvider (StaticRoutes.xml)
  • Using Environment Variables.
  • Command line arguments
  • etc.

The configuration has to be loaded during application startup and is placed into the 'TwinCAT.Ads.TcpRouter.AmsTcpIpRouter' class via constructor dependency injection and must contain the following information:

  • The name of the local System (usually the Computer or Hostname)
  • The Local AmsNetId of the local system as Unique Address in the network
  • Optionally the used TcpPort (48898 or 0xBF02 by default)
  • The static routes in the 'RemoteConnections' list.
  • Logging configuration.

Actually the configuration is not reloaded during the runtime of the 'TwinCAT.Ads.TcpRouter.AmsTcpIpRouter' class. Please be aware that the "Backroute" from the Remote system linking to the local system (via AmsNetId) is necessary also to get functional routes.

Example for a valid 'appSettings.json' file (please change the Addresses for your network/systems.)

{
  "AmsRouter": {
    "Name": "MyLocalSystem",
    "NetId": "192.168.1.20.1.1",
    "TcpPort": 48898,
    "RemoteConnections": [
      {
        "Name": "RemoteSystem1",
        "Address": "RemoteSystem1",
        "NetId": "192.168.1.21.1.1",
        "Type": "TCP_IP"
      },
      {
        "Name": "RemoteSystem2",
        "Address": "192.168.1.22",
        "NetId": "192.168.1.22.1.1",
        "Type": "TCP_IP"
      },
    ]
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "System": "Information",
      "Microsoft": "Information"
    },
    "Console": {
      "IncludeScopes": true
    }
  }
}

Alternatively a "StaticRoutes.Xml" Xml File can configure the system equally. Don't forget to add the 'StaticRoutesXmlConfigurationProvider' to the Host configuration during startup (see FirstSteps below).

An example of the local "StaticRoutes.xml" is given here:

<?xml version="1.0" encoding="utf-8"?>
<TcConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\TwinCAT3\Config\TcConfig.xsd">
  <Local>
      <Name>MyLocalSystem</Name>
      <NetId>192.168.1.20.1.1</NetId> 
      <TcpPort>48898</TcpPort> 
  </Local>
  <RemoteConnections>
    <Route>
      <Name>RemoteSystem1</Name>
      <Address>RemoteSytem</Address> 
       
      <NetId>192.168.1.21.1.1</NetId>
      <Type>TCP_IP</Type>
    </Route>
    <Route>
      <Name>RemoteSystem2</Name>
      <Address>192.168.1.22</Address> 
       
      <NetId>192.168.1.21.1.1</NetId>
      <Type>TCP_IP</Type>
    </Route>
  </RemoteConnections>
</TcConfig>

Alternatively, the configuration can also be set via Environment variables.

PS> $env:AmsRouter:Name = 'MyLocalSystem'
PS> $env:AmsRouter:NetId = '192.168.1.20.1.1'
PS> $env:AmsRouter:TcpPort = 48898
PS> $env:AmsRouter:RemoteConnections:0:Name = 'RemoteSystem1'
PS> $env:AmsRouter:RemoteConnections:0:Address = 'RemoteSystem1'
PS> $env:AmsRouter:RemoteConnections:0:NetId = '192.168.1.21.1.1'
PS> $env:AmsRouter:RemoteConnections:1:Name = 'RemoteSystem2'
PS> $env:AmsRouter:RemoteConnections:1:Address = '192.168.1.22'
PS> $env:AmsRouter:RemoteConnections:1:NetId = '192.168.1.22.1.1'
PS> $env:AmsRouter:Logging:LogLevel:Default = 'Information'
PS> dir env: | where Name -like AmsRouter* | format-table -AutoSize

                })
                .ConfigureLogging(logging =>
                {

                })
            ;
    }

public class RouterWorker : BackgroundService
{
    private readonly ILogger<RouterWorker> _logger;

    public RouterWorker(ILogger<RouterWorker> logger)
    {
        _logger = logger;
    }

    protected override async Task ExecuteAsync(CancellationToken cancel)
    {
        AmsTcpIpRouter router = new AmsTcpIpRouter(_logger);

        //Use this overload to instantiate a Router without support of StaticRoutes.xml and parametrize by code
        //AmsTcpIpRouter router = new AmsTcpIpRouter(new AmsNetId("1.2.3.4.5.6"), AmsTcpIpRouter.DEFAULT_TCP_PORT, _logger);
        //router.AddRoute(...);

        await router.StartAsync(cancel); // Start the router
    }
