Template:M-bus: Sending M-Bus data to server

The information on this page is updated in accordance with the 00.07.10 firmware version .

Summary

This article contains instructions on how to send M-Bus data to the server using various protocols.

Configuration overview & prerequisites

Before we begin, let's take a look at the configuration that we are attempting to achieve and the prerequisites that make it possible.

Prerequisites:

• TRB143;
• M-Bus device;
• Server;
• An end device (PC, Laptop, Tablet, Smartphone) for configuration;

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Adding M-Bus devices

The M-Bus Settings section is used to configure the general service functionality. To set up a new M-Bus instance, go to Services → M-Bus → Client. Add a new device to the configuration press button which is shown below.

Device configuration

---

You will be granted to a new window. Configure your M-Bus device accordingly:

1. Name: Enter the desired name of the M-Bus device
2. Address type: select which M-Bus address will be used
3. Primary/Secondary address: specify M-Bus address

Test if the M-Bus device is reachable by a specified primary/secondary address. To do so click on . You might get on of two outputs:

• If you have specified correct primary/secondary address, you will receive:

• If you have specified incorrect primary/secondary address, you will receive (if you do not know what address should be used, refer to the Scanning for available M-Bus devices (PRIDET URL) secion:

Once finished, save the configuration by clicking .

Scanning for available M-Bus devices

---

If you are not sure what address your M-Bus devices have, you can try scanning for the available M-Bus devices. To do so click on button.

Scan settings

---

You will be granted to a new window. Configure scan settings accordingly:

1. Scan type: select which M-Bus address will be scanned
2. Scan range: From what M-Bus address scanning will start and M-Bus address until scanning will be performed.

To start the scan click on button.

Found devices

---

Once the scan is finished you should see the list of M-Bus devices that TRB143 were able to find:

You can either (1) M-Bus devices primary address or (2) to the M-Bus devices list.

Gathering M-Bus data

If the device successfully added to the list, under the General settings you should see that the Status changes to Active.

Data collecting groups

---

To reach data collecting groups configuration press button. button lets you to create a new instance.

Data collecting group instance

---

Each data collection group contains the following information. Configure device accordingly:

1. Enabled: on
2. Name: desired name of the instance
3. Period: desired time duration between data retrievals
4. Data type: desired data type to process the received data. Depending on your needs you can select between 5 different data types: JSON, XML, ASCII, Hexadecimal and Binary.

You can check if your configuration works accordingly by pressing the button. You should see the data in a pop-up field:

Group values

---

To reach group values configuration press button:

There you can adjust additional settings:

1. Enable: Enable/disable data group value.
2. FCB toggle: FCB (Frame Count-Bit), one-bit counter for reliable server-client communication.
3. Manufacturer information: Select to include manufacturer information in the payload.
4. Selected parameters: Select to include the all parameters saved from device, or a custom subset of them. If the custom is selected you can specify frame, record numbers and also a paramater

Sending data to the server

The Data to Server feature provides you with the possibility to set up data senders that collect data from various sources and periodically send it to remote servers. This section will walk you through configuring the Data to Server to send M-Bus data to the desired HTTP or MQTT server.

Data to Server configuration

---

To set up Data to Server, navigate to Services → Data to Server. Enter desired name of the instnace and hit button which is shown below.

Data configuration

---

Each data collection group contains the following information. Configure device accordingly:

1. Name: desired name of the instance
2. Type: M-Bus data
3. Format: custom or JSON depending on a need.

Once finished configuring Data configuration tab click on button.

Collection configuration

---

Once finished configuring Collection configuration tab click on button.

Server configuration

---

This section contains information on how to configure MQTT and HTTP servers information.

HTTP configuration

---

1. Type: HTTP
2. Server address: desired server address

Note: not specified fields are optional.

MQTT configuration

---

1. Type: MQTT
2. Server address: desired server address
3. Topic: MQTT topic to be used for publishing the data.

Note: not specified fields are optional.

Once finished configuring Server configuration tab click on button.
