Inside OB10: s M108.0 Inside FC108 This bit is then used to trigger a program. The bit M108.0 is never set do you have to Restart the CPU before this becomes active or start it somewhere else??? Cheers Jonny

After that, your Time of day interupts should work as configured. Having said that,there's a coupleof ways to configure and enable them and thelink to an FAQ below has more details on this. Setting the time-of-day interrupt P.S:Using <F1> on OB10 as well as the HELP button on the"Time-of-Day Interupts" tab on the CPU properties will also give you additional "help". I hope this helps

Open PLC/diagnostic setting/set TOD. As shown in the attached picture, you can mark the "Take from PC/PG" check box to syncronise time between CPU and your PG. Or you can set any other time.
