Summary
The M-Bus (Meter Bus) is a cost-effective fieldbus communication protocol for transmitting energy consumption data. A central client – in this case {{{name}}} – communicates via a two-wire bus (up to max. 250 servers per segment) with bus devices (e.g., heat meter, water meter, electric meter, gas meter).
This manual page provides an overview of the M-Bus functionality in {{{name}}} devices.
Client
General settings
The M-Bus device configuration section is used to configure the general service functionality. The figure below is an example of the M-Bus Settings and the table below provides information on the fields contained in that section:
| Field | Value | Description |
|---|---|---|
| Status | Inactive | Active | Status of service, whether it is currently running. If it is active, it will also show how long it has been running. |
| Baud rate | 300 | 600 | 1200 | 2400 | 4800 | 9600 ; default: 2400 | Specifies the M-Bus server network baud rate. |
Devices
To add new device to configuration press Add button which is shown below.
The Devices section is used to configure the general device instance. The figure below is an example of the M-Bus device and the table below provides information on the fields contained in that section:
| Field | Value | Description |
|---|---|---|
| Name | String; default: Device 1 | Display name of device configuration. |
