Hello,

I'm making time interrupt program with Time of day OB.

Now i checked DB31.DBW44 (DB PLC DATE.DATE) adding 1 every minute.

But why DATE SET bit ON constantly?

I need pulse signal every minutes.

ADD function behavior is good.. But Bit signal is constantly ON .

How to make this????

Please check attached photo.
