Programming with TAPPS2 / M-Bus 

 

37 

M-Bus 

The  M-Bus  is  a  master/slave  system  for  reading  data  from  energy  and  volume  meters  (electricity, 
heat, water, gas).  
The CAN-BC2 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 bus converter (master) cyclically reads the values from the individual 
devices. The interval time is adjustable. 

As  a  master,  this  bus  converter  is  therefore  suitable  for  the  parallel  connection  of  up  to  four  
M-Bus meters (slaves).

  

In  total

,  a  maximum  of  32 M-Bus  values  can  be  read  per  bus  converter.  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.  

Settings 

 
 
 
In  the  Device  settings /  M-Bus  menu,  the  general 
settings for the M-Bus and the addresses of the M-Bus 
devices are defined. 
 
 
 
 
 
 
 

 

 
 

Baud rate 

The standard baud rate of the M-Bus devices is 
2400 Bd. The factory setting does therefore not 
usually need changing. 

Interval time 

The  readout  intervals  can  be  adjusted  from 
10 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 

primary

  slave 

address

 must be entered (between 0 and 250). 

The  primary  slave  address  is  set  at  the  M-Bus 
device  in  accordance  with  the  manufacturer's 
instructions. 
The  same  slave  address  cannot  be  used  twice 
in the M-Bus network.
