# Send Value / String

![TS SendValue](https://1704635928-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FH5etzy4TvPRLxLRNfHlb%2Fuploads%2Fgit-blob-a90de52151e71c821986e37ac1eb191b6ac1b420%2FTS_SendValue.png?alt=media)

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**.

{% hint style="info" %}
For send value to work correctly it is important to name the values consistently throughout the whole testplan.
{% endhint %}

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

![TS SendValue Hist](https://1704635928-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FH5etzy4TvPRLxLRNfHlb%2Fuploads%2Fgit-blob-b0aa9f472a12830c33e542964c45d5b0893fb950%2FTS_SendValue_Hist.png?alt=media)

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

{% hint style="info" %}
It is important that the custom column name is exactly the same as the value name used in this step type.
{% endhint %}

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

| Scenario                                                | Outcome                                                                                                                                                                                                                                               |
