I have to save all the sensors que eat to bypass and so the user que of this action and the time of day . 3 variables. I need to keep this save for 15 days . Passing this days I have to show the history about this sensors . In other words, show the history about my 3 variables. Can some one explain to me how to do that ?

Hi,

From your description, it seems to me also that you need the datalog functionality. The S7-1200 and S7-1500 has a lot in common so there may be things you can carry over from the example already given.

As alternative please look at [LINK] - an example given by a senior user Pegaia. I will further encourage you to use the search function looking for "datalog S7-1500".

It will be worth your while to download the technical manual of the S7-1500 from the web - this manual is very complete and will help you in many aspects when working through some examples.

I should add:
Datalog function is not the only way to solve your problem, but there are added advantages. When you also configure the web server functionality, it will be possible to upload the log from PLC to PC without the need of the TIA software.   Do let us know if this consideration is not required for you.

Good luck.
