# Transparent mode now available

### Description

From now on the device supports [T1.B100](/hub/en/t1.b100/description.md) in addition to the proven **Modbus protocol** also the **Transparent Mode**. This new feature makes it possible to use serial interfaces over the network, which is a major advantage for many applications, especially in the field of building automation and industrial control. With Transparent Mode, users can address serial devices such as RS485 participants (for example M-Bus devices) via TCP/IP without additional hardware being required.

### Transparent Mode: What is it about?

In Transparent Mode, serial devices that would normally be connected directly can be integrated via the network. For many users this means less effort because no additional hardware is needed to connect RS485 devices.\\

A practical example:\
If a **CODESYS controller** needs to access a remote RS485 device, this can be realized via Transparent Mode without the devices having to be physically connected.\
This offers great flexibility because serial devices can be controlled over greater distances, which is particularly helpful in distributed networks.

### The advantages at a glance:

* **Easy integration**: Serial devices can now be controlled via TCP/IP without having to be physically nearby.
* **Cost-effective**: Existing serial devices can continue to be used without requiring additional adapters or interfaces.
* **Central control**: Remote devices can be controlled over the network just as well as locally connected ones.

### How to switch between modes:

As soon as you have installed **Version 3.20** you will find in the **Applications** section two new applications that cannot be uninstalled: the **Modbus Mode** and the **Transparent Mode**.

1. **"Activate Advanced Mode"**:\
   To view and activate the Transparent Mode, click the **gear icon ("Settings")** in the top right and enable the **Advanced Mode**. \\
2. After activating Advanced Mode, the two new applications appear in the **Applications**menu.\\

3. You make the settings for switching modes in the **Serial Settings** menu. Under the section **"Fieldbus"** you can directly select the desired mode for each port and thus flexibly decide which port should use which mode.\\

**Note**: These applications cannot be uninstalled but are firmly integrated into the system once [**Version 3.20**](https://support.powerio.com/hub/faq-and-news/en/news-blog/spaces/ltcbXgy6Y2teLoU01eGk/pages/5bc78a67b20add3c32229126af64038fde6de009#id-3.20-firmware-download) or higher is installed.

## 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-and-news/en/news-blog/transparent-mode-jetzt-verfugbar.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.
