How to use the Mbus Scan

The Mbus bus is a serial bus powered by the master (Box or Hub) with 37V, the Box/Hub can handle natively 3.6mA (3*UL) on the bus.
If you want to scan/communicate with more than 3 devices, you should use an Mbus repeater.

Hardware installation :

• Polarity is respected 
• Make sure that you have the Bus powered only by the Box/Hub (around 37V)
• All devices are on the same network configuration (baudrate/unique M-bus address/etc..)
• Wire are communication twisted pair 
• Make sure that your topology respect this one

Step 1:

Go on the configuration tab and add a new equipment using the configuration Wizard.

Then select the "Scan M-bus network" button.

Select the baudrate of your M-bus network.

Step 2:

Run a scan on primary address

-> You can choose to run the scan on primary address by using a "Full scan"

-> Or you can choose to run the scan between an address range

Run a scan on secondary address

Once the method is selected, click on the "launch the scan" button and wait for the scan to be finished.

NOTE: The scan duration can take more than 6 minutes, depending on how many meter are on the bus and the baudrate.

Step 3:

Select the datapoints you wish to monitor.
