Beckhoff.TwinCAT.Ads 4.4.0

The TwinCAT ADS API is a .NET Assembly enabling to develop own .NET applications (e.g. visualization, scientific automation) for communication with TwinCAT devices (e.g. PLC, NC or IO-devices).
     Prerequesites are

       - a TwinCAT 2 or 3 Installation (XAR-Runtime or Full)
       - .NET Framework 4.0

     Features
     
       - the implementation of ADS Clients
       - the browsing of (ADS) server side symbolic information
       - Symbolic Read/Write from/to ADS Servers (Process Images)
       - Value Change Events (ADS Notifications)
       - Support of Raw ProcessImageData, AnyType concept or full dynamic typed (type safe) symbols

Description

The package 'Beckhoff.TwinCAT.Ads' contains a client implementation for the ADS Communication protocol used by .NET Core and .NET Full Framework.
It includes everything to develop own .NET applications (e.g. HMI, Datalogger) to communicate with TwinCAT devices (e.g. PLC, NC or IO-devices).

The Root object is the TwinCAT.Ads.TcAdsClient to communicate to all variants of local and remote ADS servers and devices or the AdsSession object.

Requirements

  • .NET Framework 4.0 (Versions for CLR2 and WindowsCE are available on demand, please contact Beckhoff)
  • A TwinCAT Installation (ADS, XAR or Full)

First Steps

The following code instantiates an AdsClient object, connects to a target device (here the local System Service)
and reads the ADS state asynchronously.

using System;
using TwinCAT.Ads;

namespace AdsAsyncTest
{
    class Program
    {
        static void Main(string[] args)
        {
            using (TcAdsClient client = new TcAdsClient())
            {
                    UInt32 valueToRead = 0;
                    UInt32 valueToWrite = 42;

                    client.Connect(AmsNetId.Local, 851);
                    adsClient.WriteSymbol("MAIN.nCounter", valueToWrite, false);
                    valueToRead = (uint)adsClient.ReadSymbol("MAIN.nCounter", typeof(UInt32),false);
            }
        }
    }
}
