Factorysql problem

In factorysql everyday the data is getting dropped at certain time (3.00 am) , in mysql it is writing constant values.

The problem gets resolved once we reset the groups in factorysql.

In Factorypmi we are getting real time data.

That is indeed strange. Usually when things happen around a certain time regularly, it’s due to some maintenance procedure going on at that time- database backup, virus scan, etc.

Are there any operations scheduled for that time?

On the FactorySQL front, are there any messages from around that time in the Error log (Help>Log Viewer)? When you go to the groups, are the values being updated in the frontend? Is the “execution count” incrementing?

Also, which OPC server are you using?
