# Send Value / String Value

![TS SendValue](/docs/assets/ltt/assets/ts-sendvalue.png)

With the **LTT Send Value** step type you are able to send one or more **named values** to the station display. We also call those **LTT runtime values**.

> For send value to work correctly it is important to name the values consistently throughout the whole testplan.

Optionally, you can configure one or more of those values as **additional history columns**.

![TS SendValue Hist](/docs/assets/ltt/assets/ts-sendvalue-hist.png)

To do so, you need to edit the [history configuration file](/en/docs/ltt/documentation/ltt-gui-manual/configuration/historyconfiguration) and add a **custom column** for each runtime value you want to have as a history column.

> It is important that the custom column name is exactly the same as the value name used in this step type.

In combination with history column configuration there are 3 different usage scenarios for LTT runtime values possible:

| Scenario                                                | Outcome                                                                                                |
| ------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| Without custom column entry                             | Values are displayed in [station display](/en/docs/ltt/documentation/ltt-gui-manual/lttgui/mainwindow/stationdisplay) only.                                     |
| With custom column entry                                | Values are displayed in [station display](/en/docs/ltt/documentation/ltt-gui-manual/lttgui/mainwindow/stationdisplay) and [history file](/en/docs/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata). |
| With custom column entry (`ShowInStationPanel="false"`) | Values are displayed in [history file](/en/docs/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata) only.                                     |
