# Updates and versions

## Which updates are available?

The system is modular, 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 contains the system. On delivery you will always receive a device with the most recent firmware version.

**Firmware download**

* The current firmware can be found 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/Other:**

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

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

* The bootloader is responsible for starting the system and provides the option to restore the device to factory settings. On delivery you will always receive a device with the most recent bootloader version.

**Bootloader download**

* The current firmware can be found 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/Other:**

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

**Application downloads**

* The current firmware can be found 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/Other:**

* Only one application can be installed per application at any time
* Upgrading applications is always possible and recommended.
* A downgrade is possible. For this, the newer version must be uninstalled and the desired older application can be installed.
* In the download area, the notes about minimum firmware versions must be observed.
  {% endtab %}
  {% endtabs %}

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

## Reading versions via the web interface

{% endtabs %}

## 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 there is no need to access the web interface of the endpoints.

{% 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 versions

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