Gets or sets a value indicating whether the TcAdsClient object uses a client cylce for the notificatons. If ClientCycle is set to false, the ADS that has been addressed writes the data cyclically to the TcAdsClient object. The smallest possible time is the cycle time of the ADS device. For the PLC, this is the task cycle time. The cycle time can be handled in 1 ms steps. If you enter 0 ms as the cycle time, then the data is sent to the TcAdsClient object with every cycle of the ADS device task. If ClientCylce is set to true, the TcAdsClient object polls the variables cyclically. The timer that initiates the read / write runs in Windows NT/2000 user mode, which means that the time behaviour strongly depends on the loading of the system. Gets or sets a value indicating whether the TcAdsClient object synchronizes the incoming notifcations. If Synchronize is set to true, the notifications are synchronized onto the Main thread. This is necessary for Windows Forms projects. In Console Application this property should be set to false.
