Now, assign the correct controller types to the other modules. If a controller was marked as a
server, the menu items of the commissioning are shortened because the main parameters are
set via the client.
COMMISSIONING
Language
Controller type
Finish with protocol
Finish without protocol
To complete the commissioning at the servers, confirm
the items
Finish with protocol
(for this, a USB flash drive
must be connected to the controller) or
Finish without
protocol.
Now, at the client, go to the menu item
Scan Modbus
. In the following, a search run starts which
identifies the connected controllers in the cascade system. If a server was detected by the
client, it is marked with
OK.
After that, leave the menu via the
Back
button.
Now, the automatic synchronisation of all controllers in the cascade starts. When it is
completed, the message "
Synchronisation finished
" is displayed.
Please note: If the number of the communicating domestic hot water modules is modified within
the cascade (e.g. server X is being maintained) or the MB3.10 is switched on or off,
Scan Modbus
must be repeated to specify the exact number of the participants within the
Modbus network.
