# Variables for manual variables

This special group is created automatically by ACRON, and includes the variables not assigned to any provider.

This variable is a special variant of the external variable for the manual variables.

As they are not assigned to any provider, they cannot import any data from a control system/PLC, but must rely on manual data input.

ACRON can automatically generate the required variable when creating a new manual variable.

## Variable group <a href="#variablengruppe" id="variablengruppe"></a>

The variable groups provide a more user-friendly structuring of the external variables. They can be broken down further into subgroups, which is particularly useful in enhancing the clarity of large-scale plant installations.

Variables can be moved within the groups by [drag & drop](/acron-9.3/en/erklaerung_zur_bedienung.md#drag-drop).

## Name <a href="#bezeichnung" id="bezeichnung"></a>

Name of the variable group

## Variable without provider <a href="#variable-ohne-provider" id="variable-ohne-provider"></a>

Variables without providers cannot import any data from a control system/PLC. They must rely on manual data input.

Variables can be moved within the groups by [drag & drop](/acron-9.3/en/erklaerung_zur_bedienung.md#drag-drop).

Note

Variables in use (such as by process variables) can only be deleted or deactivated once the respective assignment has been canceled.
