Hallo,

stimmt, da steht es genau beschrieben drin.

Anbei, eine Implementierung in C#:

using System;
using System.Threading;
using System.Windows.Forms;

namespace OpcTesting
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            WaitHandle waitHandle = new EventWaitHandle(false, EventResetMode.ManualReset, @"Global\SimaticNetPcStationUpEvent");
            ThreadPool.RegisterWaitForSingleObject(waitHandle, OpcReady, null, 10000, false);
        }

        void OpcReady(object state, bool timedOut)
        {
            if (timedOut)
            {
                MessageBox.Show("Timeout");
            }
            else
            {
                MessageBox.Show("Ready");
            }
        }

    }
}


Vielen Dank
