System function for storing variable per each day/week/month

Post by Maksim Nevmer » Wed Jul 04, 2018 12:45 am

Dear Colleagues,
I need to find solution for the following task:

I have two flowmeter sensors: boiler fuel input, boiler fuel output. The difference of its values gives a consumed fuel consumption in time. In SIMATIC controller project it is necessary to store next fuel consumption relative values: per day, per week, per month, per year. It is desirable to have a store related with calendar.

Is there some Step7 system function to solve such task?
Maybe somebody have similar sample projects?

Sincerely yours, Maksim
