If you change and save values or error codes in one or more time series, AquisNet proceeds as follows.

▪Changes are written directly to one or more basic production time series.

▪These changes remain persistently present in the time series.

▪The data status before the changes is saved per transaction.

▪This makes it possible to access the data before the change. The data is used in the event of a possible later restoration of a previous data status.

▪To reduce the storage volume and the organisational effort of the transactions, AquisNet only saves the "affected" time range at a time and this - see above - with the data status before the changes.

▪In addition to the pure measurement data of all affected time series before the change, AquisNet stores an identifier, a comment and the responsible user in transactions. Furthermore, the system stores the date and a transaction ID.

▪When you close the table, the system displays a save dialog.

▪If you confirm this with [Yes], the system generates a transaction:

▪To do this, enter a transaction name and a comment.

▪Save the entries.

The transaction is transferred to the data storage.

▪The transaction can now be opened in the time series browser in the tree view. To do this, select one of the two entries for transactions from the drop-down list box.

The transaction for saving changes comprises these steps:

▪Filter time series graph using an error code group

▪Filter time series table using error codes
