S7 Time of Day interrupts

Hello,

New to S7 and want to collect end of shift data. Would like to code in OB 10,11 eg. 8am and 8pm interrupts. Need these to be static. Could anybody please help me out on calling these interrupts. Is there a memory location to set interrupt Or do you have to use system functions to initialise on each power-up within OB 100. Manuals are confusing.
Example would be great.

Thanks in advance

Which CPU are you using ? Go to the hardware config editor and double click on the CPU. You will see a time-of-day interrupts tab, click on this and then activate, set your execution start date/time etc. Insert code in OBxx to do your data collection and storing.
