The data points can be used for data point mappings and for mapping BACnet objects, for example.
The

M-Bus > Counter Scan
On this page, you can search for counters (counter scan) with the gateway on the M-Bus. Using the
identified counters, configuration files for the M-Bus and BACnet objects or Profinet data points are
then automatically generated.
Two M-Bus search options are available:
•
Primary address mode
•
Secondary address mode
Identified counters are then polled later on in the mode with which they were scanned here. This
means that a counter identified in primary address mode, for example, is also polled with the primary
address.
Searching using the primary address
In the M-Bus, every counter can be given a unique primary address between 0 and 252. During
commissioning, this primary address must be assigned to every counter. During scanning, the
addresses of the counter in the specified area are polled individually. A responding counter is
considered identified here and is listed as a scan result. Advantages of counter polling via primary
address:
•
Quick poll
•
When a counter is changed, only the same primary address needs to be set in the counter.
(This only applies if the same counter is installed again.)
Searching using the secondary address
Each M-Bus counter has a unique identification address, comparable to an Ethernet MAC address. To
communicate with a counter via this address, it must be selected using a special M-Bus command.
Only then is it possible to poll the counter. This must take place before any attempt to communicate
with the counter. Advantages of counter polling via secondary address:
•
No previous configuration of primary addresses in the counters necessary.
