Error codes and error code groups are used to assess measurement data qualities and their handling. In this chapter you will learn how AquisNet uses the error codes, which settings you can make as a user and how to work with these settings.

AquisNet assigns a quality statement to each individual measured value during import by assigning an error code. Based on this error code, AquisNet decides on the quality and thus the validity of measured values. AquisNet allows it users to create their own error codes. These error codes are listed in a table that can be called up in the main menu under the menu item Time Series > Error code > Administrate status codes. In addition to the numerical value and a short description of the code, this table also contains a textual short representation (display value, also called error code). The error code is always displayed in the value tables of the DMO, so that the user can easily recognise the status of the measured value without having to memorise its numerical values. The text display can be changed by the user in the editing dialog of error codes.

In the user interfaces of AquisNet, the display value (error code) of the error code is always displayed.

Deleting error codes cannot be performed in the AquisNet DMO user interface for consistency reasons.

For base production data, the quality information on measured values is supplied as a "data flag" during import. According to these "Data Flags", AquisNet error codes are automatically assigned to the measured values during import. There is no graphical user interface available for the configuration of "Data Flags" and for mapping with the AquisNet error code system. However, it is possible to make changes in the data management. Note that only trained specialists are allowed to do this. If you are interested, contact KISTERS directly.

To have different quality perspectives when evaluating measurement data, users can create their own error code groups. The membership of an error code in an error code group determines, for example, the validity of a measured value. System error code groups are provided to define these central properties of the system. Predefined groups contain, for example, all valid error codes, all invalid ones, etc. The maintenance of the assignment of error codes to the groups is done by the user, whereby new error codes can be fully integrated into the system at any time. Error code groups can be used as display filters in the DMO, but also as filter criteria for report outputs, so that, for example, only valid or only invalid values can be output.
