Hi to All,

In my panel, i've configured a trend and alarm histroy.

For the trend i follow a procedure from support siemens, were for show the logged trend and the actual value updated, for each variable i've put, one configured like a log, and the smae one configured like a cicle update.

The starnge things is that the trend work properly for a few hours, and after that i'm not able anymore to se any value.

In the diagnostic page i found this error:

ID 80052, Error in case of read acces a log file.

At the same time the alarm history page is empty.

Someone knows thw reasone?

Thanks to all

Duccio.
