zenOn Archive Server

zenon saves archive data in its own binary format. This makes the archives highly performant. They can also be easily compared and managed, and the data cannot be externally manipulated. The latter is especially important in regards to the requirements of FDA CFR21 Part 11. Read more about this in the chapter FDA. All data can also be saved in CSV, dBase, or in XML, or in an SQL database (see zenon SQL server). zenon SQL Server). zenon divides archives cyclically to individual archive files – this way an archive does not grow endlessly large and following archives stay computable. The time interval is freely configurable. Also through functions archives can be started and stopped, e.g. with a shift or batch change.

In order to save space on the data carrier, archives can be evacuated automatically in data formats such as XML, CSV, or dBase, as well as copied onto backup systems or simply deleted.

zenon can do a lot more:

Following archives

Following archives are used for data compression. The sum, average, maximum and minimum are calculated from the archives over a freely selectable timeframe, and the resulting value is saved in a new archive. The concise data preparation of the values (data reduction, automatic calculation of the average from the data, such as a recorded hour) makes it easier to detect trends.

Archives in the multi-project administration

The zenon archive server has perfect command of multi-project administration: In an archive of an overriding project, values from a subproject are archived. This way values from multiple facility sections and various projects can be stored together and therefore optimally compared. The supplying zenon server can even be a CE-terminal. All values within a heterogeneous system (PC and CE) can be seamlessly recorded in a central archive.

Batch archiving

Batch archiving allows for the easy allocation of batch designations to an archive. The batch designation is recorded in a string variable and saved with the archive. The zenon modules Extended Trend or Report Generator then allow comfortable filtering on the batch name.
