# Dialog - Automatic generation

By selecting groups and/or external variables with [measured value archiving](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/variablengruppe/register_mew-archivierung.md#messwertarchivierung) activated, you can create new auto variables below the active selection in the main tree. The identification and name of this new auto variable are formed on the basis of the identification of the selected external variable.

If the external variable has no name, the name of the generated process variable is formed from the identification of the external variable. If a [description](/acron-9.3/en/anlagenkonfiguration/verfahrensgroessen/autogroesse/register_allgemein.md#beschreibung) is stored for the external variable, this value is imported into the description of the process variable.

In the [process data linkage](/acron-9.3/en/anlagenkonfiguration/verfahrensgroessen/autogroesse/register_allgemein/prozessdatenverknuepfung.md) of the auto variable the external variables are entered by way of allocation.

If a [data recording range](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/variablengruppe/register_mew-archivierung.md#datenaufzeichnungsbereich) is specified for the external variables, those values are adopted for the [measured value range](/acron-9.3/en/anlagenkonfiguration/verfahrensgroessen/autogroesse/register_allgemein.md#messwertbereich) of the process variable, otherwise the measured value range is populated by the default values.

Choose "Auto variable template" to select a process variable as a template. The generated auto variable adopts all the settings of the template process variable (Exception: Process data linkage - here, logically, the selected external variables are still entered).

Note

If the identifier of an external variable is changed, the process data linkage of the assigned process variable is automatically adapted. Other changes, such as to the name or the data recording range, are not applied.
