# Updates and versions

## Which updates are available?

The system has a modular design, which gives us the ability to provide updates quickly and easily. Updates are divided into 3 areas:

{% tabs %}
{% tab title="Firmware" %}
**Definition - *****Firmware***

* The firmware includes the system. Upon delivery, you will always receive a device with the latest current firmware version.

**Firmware Download**

* The current firmware is located on the support page in the [download area](/hub/downloads/en/powerio-downloads/t1.b100-firmware.md).

**Update option**

* Via the **web interface** of the device
* or the **Device Manager** (Bulk Updates)

**Recommendation/Miscellaneous:**

* Always perform an upgrade only to a newer version.
* Should problems occur with a new version, then [contact us](https://www.powerio.com/de/kontakt) please.
* A downgrade is possible, but should only be done in consultation with powerIO Support.
  {% endtab %}

{% tab title="Bootloader" %}
**Definition - *****Bootloader***

* The bootloader is responsible for starting the system and offers the possibility of restoring the device to factory settings. Upon delivery, you will always receive a device with the latest current bootloader version.

**Bootloader Download**

* The current firmware is located on the support page in the [download area](/hub/downloads/en/powerio-downloads/t1.b100-firmware.md).

**Update option**

* Via the **web interface** of the device
* or the **Device Manager** (Bulk Updates)

**Recommendation/Miscellaneous:**

* Always perform an upgrade only to a newer version.
* A downgrade is not possible
  {% endtab %}

{% tab title="Applications" %}
**Definition - *****Applications***

* An application can be installed flexibly as needed on a device. An overview of the applications can be found [here](/hub/en/applications/available-apps.md).

**Application Downloads**

* The current firmware is located on the support page in the [download area](/hub/downloads/en/user-applications/codesys.md).

**Update option**

* Via the **web interface** of the device

**Recommendation/Miscellaneous:**

* Only one application can be installed per application
* An upgrade of applications is always possible and recommended.
* A downgrade is possible. To do so, the newer version must be uninstalled and the desired older application can be installed.
* In the download area, note the information on minimum firmware versions.
  {% endtab %}
  {% endtabs %}

{% hint style="warning" %}
Please always obtain the update files only from the official source in the support area. The file extension for update files is \*.PIOP
{% endhint %}

## Reading versions with the powerIO Device Manager

With the Device Manager, you can read the firmware and bootloader versions in a network with one or more powerIO Devices. This means you do not need to access the web interface of the end devices.

{% stepper %}
{% step %}

#### Installing and using the powerIO Device Manager

* Install the powerIO Device Manager
* Desktop application OR directly as a "User Application" on a powerIO device\
  \
  Information about the [powerIO Device Manager can be found here](/hub/en/applications/available-apps/device-manager.md)
  {% endstep %}

{% step %}

#### Start the application and read out versions

* After starting the application, the network is searched for devices and the respective versions are displayed in the column

<figure><img src="/files/b1b44b5d8beb02d40a75faaa0e5487847dcf96a4" alt=""><figcaption></figcaption></figure>

## 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://support.powerio.com/hub/faq/faq-en/powerio-system-faq/updates-und-versionen.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.
