Hello S7Maniaq OB10 can "know" when its time has come in a number of different ways. The "traditional" (and easiest) one is to configure and "activate" OB10via the CPU properties from HWconfig. Once done and HWconfig is downloaded, OB10 will be called by the operating system as per time of day configuration (e.g. every day at 9:00 am, once on 24.12.2009at0:00 etc.). The alternative wayis configuration via SFC28,activation via SFC30 and (if desired) deactivation viaSFC29. You can also sort of "mix and match" the two ways (e.g. configure the desired "time of day"in the HWconfig but leave the "active" tickbox unchecked. Thenuse SFC30 and/or 29 to "activate" or "deactivate" them). I hope this helps

By doing this my problem is also solved i guess ?
