Time-of-day interrupt can be configured so that abon reaching the target date and time, the associated OB is executed once and only once, or every minute, hourly, daily, monthly or yearly. In your case, in execution selection, you will select yearly and identify date and time for execution and it will call the TOD interrupt OB at this date once every year.

Best regards, Hamid Hosseini HI Hamid Hosseini, in ur program u used sfc1 to read date & time at hd1 but u didnt use it in set the m10.0 pulse? and why u load lb20 and convert to integar then transfer to mb200 then transfer mb200 to mb202 then compare equal not them to set m10.0 ??

Hello again, Perhaps it was not a clear way to solve a problem like that with some mysteries but my Date and Time variable starts at the local area byte number 20.See attached file plus consult the online manual of STEP 7 for structure of "Date and Time variable". NOTE1:If you want to remove BTI instructions, for 50:=(3*16)+2 you should replace W#16#32. I hope thsee rough explanations help, Hamid Hosseini Attachment Date_and_time.zip (107 Downloads)
