M-Bus
The M-Bus is a master/slave system for reading data from energy and volume meters (electricity,
heat, water, gas).
The M-Bus input is designed for up to 4 M-Bus "unit loads". Up to 4 M-Bus meters, each with 1 unit
load, can therefore be connected. The controller (master) cyclically reads the values from the indi -
vidual devices. The interval time is adjustable.
As a master, the controller is therefore suitable for the parallel connection of up to four M-Bus me -
ters (slaves).
In total, a maximum of 32 M-Bus values can be read per module. There must only be one master in
the M-bus system.
This menu contains all the information and settings needed to set up an M-Bus network.
For the use of the M-Bus interface, the corresponding jumper must be inserted in the correct posi -
tion (see installation instructions "Jumper position J1 and J2") .
Settings
In the M-Bus menu/settings, the general settings for the M-Bus and the ad -
dresses of the M-Bus devices are defined.
Baud rate
The standard baud rate of the M-Bus devices is 2400 Bd. The factory set -
ting does therefore not usually need changing.
Interval time
The readout intervals can be adjusted from 30 seconds to 2 days. Longer
intervals use up less battery life in battery operated M-Bus meters
M-Bus device 1-4
For every connected M-Bus device, enabling must be set to "Yes" and the
slave address must be entered (between 0 and 250).
