6.3.21 Set wired M-Bus mode
Set how wired M-Bus interface will transport information to requesting M-Bus master; Auto or in
Container mode. The Auto mode will try to transport the data to requesting M-Bus master as unmanaged
data received from the wireless M-Bus slave. The Container mode will encapsulate the complete wireless
M-Bus telegram in a container. The Container mode can be useful if key handling (decryption of
telegrams), should be handled centralized and not within the CMeX50.
See section 6.1.4 for more information about Auto and Container.
