# Station Display

The test station display is the central part of the main window and shows the configured test stations as a rectangle, which contains various information about the individual test stations.

{% hint style="info" %}
A **test station** represents the physical location where a **device under test** (DUT) can be connected to the LTT. The LTT may have more than one test station.
{% endhint %}

1. test station number ([more info](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f3projectwizard/teststationconfiguration.md))
2. DUT type and name ([more info](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f11testconfiguration.md))
3. runtime values ([more info](/ltt/documentation/ltt-gui-manual/teststand/customsteptypes/sendvaluestringvalue.md))
4. requested state (e.g. *start requested*, *stop requested*)
5. custom status message or error text ([more info](/ltt/documentation/ltt-gui-manual/teststand/customsteptypes/sendstatus.md))
6. current runtime | cycle counter | error counter(s) ([more info](/ltt/documentation/ltt-gui-manual/lttgui/errorstatuscolors.md))

A test station display can have the following appearances:

![Station Off](/files/N7fqNKrqbP3OQQNxS0a3) **Stopped test station** Status text is "OFF". Runtime values are not displayed.

![Station Running](/files/1Ac17Dquo1Dufg2Qsd63) **Running test station** Status text und runtime values are updated from TestStand. Runtime gets updated periodically.

![Station Limit Error](/files/RcpjINy3mjqiSIteh8g9) **Error limit reached** Status text is "error limit reached \[nnnn]", where \[nnnn] is the error number ([more info](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f5limitconfiguration.md)) of the corresponding limit test, whose error limit is reached. A test station stops if a limit test has reached its error limit. Details can be found in [history log](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata.md).

![Station Limit Not Found](/files/NAaLcvWytSp6vX5ry7fX) **Limit not found** Status text is "limit not found". The test station stops if a limit test step cannot find its limit. Details can be found in [history log](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata.md). See [troubleshooting](/ltt/documentation/ltt-gui-manual/troubleshooting/limitnotfound.md) for further explanations.

![Station TS Error](/files/o5Yluzt1cak0QDM6Pe6Z) **Testplan error** Status text is "testplan error". The test station stops if there is an error during TestStand execution (e.g. syntax error). The exact error reason is shown as a tooltip if the mouse pointer is moved over the status text. Further details can be found in [history log](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata.md). See [troubleshooting](/ltt/documentation/ltt-gui-manual/troubleshooting/testplanerror.md) for further explanations.

![Station GUI Error](/files/4MsjypN8TkDAiMJiCjf4) **GUI error** The test station stops if there is an error in GUI software. This can be due to a software bug but also due to invalid data sent from TestStand to GUI. The exact error reason is shown as a tooltip if the mouse pointer is moved over the status text. Further details can be found in [history log](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata.md). See [troubleshooting](/ltt/documentation/ltt-gui-manual/troubleshooting/guierror.md) for further explanations.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.irs.systems/ltt/documentation/ltt-gui-manual/lttgui/mainwindow/stationdisplay.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
