Datalogging with S71214 - no errors but no datalog in web server

What are the status values for each datalog create, open, and write?  Are you saving them and comparing against "good" values for the status after it completes (DONE) each datalog action (create, open or write)?

In other words, check the status when the datalog blocks have done or error by saving it to a retained DB tag, or array of DB tags.

If you post screenshots of your datalog blocks and the DB(s) used to create the header details, we may be able to do more than guess.

Did you start with the Siemens datalog example project or did you do it all on your own?  If you say "all on your own", that's the problem.  It can get tricky when odd things happen, and the Siemens example project for handling datalogs covers the odd situations as well as the normal ones.

Hi everyone,

I'm working whit a S71214 (6ES7 214-1AG40-0XB0) FW 4.4 and a memory card of 24MB size (6ES7954-8LF03-0AA0).  

To make a datalogging my program uses Datalog Create, Datalog Open and Datalog Write. DataLog Open it s used in case that the Datalog already exist to open it and write it.

The thing is i already done this a few times without any problem. But now it seems to be no errors at all but looking at the web server none datalog exist.

Please any clue?

Regards
