# Module Configuration

{% hint style="info" %}
[Click](https://github.com/irs-systems/IRS-LTT/blob/GitBook/doc/30%20User%20Documentation/.gitbook/assets/ltt_module_config.xml) to open the module configuration file `ltt_module_config.xml`.
{% endhint %}

{% hint style="info" %}
For training or demonstration purposes you can take the default module configuration and go on with your setup.
{% endhint %}

The module configuration's main purpose is to configure the drivers for LTT standard hardware, which is:

* power supplies (for the DUT's)
* temperature sensors (for climatic chambers)
* temperature chamber contact (TCC) (digital I/O)
* uninterruptible power supply (UPS)

Each LTT hardware is configured by a `<Module name="xxx"></Module>` block. The **name attribute** determines the type of hardware and the concrete instance of it.

{% hint style="info" %}
A LTT can have multiple instances of a power supply and/or temperature sensor, but only one TCC and UPS.
{% endhint %}

The name attribute value is composed of a **predefined prefix** and an **optional index** number **starting with 1**. The index number is mandatory for those hardware modules, which are able to have more than one instance, even if only one instance is used.

| Prefix | Type of hardware                          | More than one possible? |
| ------ | ----------------------------------------- | ----------------------- |
| PS     | power supply                              | yes                     |
| TS     | temperature sensor                        | yes                     |
| TCC    | temperature chamber contact (digital I/O) | no                      |
| UPS    | uninterruptible power supply unit         | no                      |

{% hint style="info" %}
After installation there is a default module configuration, containing 2 simulated power supplies and 1 simulated temperature sensor.
{% endhint %}

Each module has at least a **path parameter**, which is mandatory and pointing to the driver file for this module. A module driver is a file with the extension **.lvlibp**. All so far existing module drivers are located at

```
50_LTT_SW\LTT TS\lib\IRS.Mod
```

The path to the module driver should be provided relative to the `50_LTT_SW\LTT TS` folder.

{% hint style="info" %}
Each module type comes with a default simulation driver. That way you can run the LTT SW without having any actual hardware.
{% endhint %}

Any other parameter a module may need is provided in form of a `<Parameter name="xxx" value="yyy"/>` block. The parameters of each possible module type are explained in the following sub chapters.
