# Parameter `Field`
Default Value: `undefined`

Field for InfluxDB v2 to use for saving.

!!! Note
    If you edit the config file manually, you must prefix this parameter with `<NUMBER>` followed by a dot (eg. `main.Field`). The reason is that this parameter is specific for each `<NUMBER>` (`<NUMBER>` is the name of the number sequence defined in the ROI's).
