Nemo Posts: 3149 Rating: (171)	Hi Khalid, no problem, the moderator will move your question to WinCC [:D] Scripts like your with sleep-function are quite dangerous, so please try to avoid them. You could start a Timer on your s7-CPU and when this time is up, the timer is giving a signal to WinCC e.g. for triggering an action. http://support.automation.siemens.com/WW/view/en/2013015 nemo

Danielle Posts: 1275 Rating: (123)	Hi Khalid, As you seem to know and Nemo has emphasized, you should NOT use the sleep function, since it will stop the execution of all scripts. Have you tried creating an action and using your timer as the trigger? If it isn't one of the standard timers you could always create your timer in Tag Logging... Best regards, Danielle
