The "Create" command is used to generate a complete device list. For that, a
search is made on the KNX bus aimed at finding individual room controllers that
have the same "Geographical zone (apartment) When the RMB795B central
control unit receives a reply from an individual room controller, it is entered on the
device list.
The search process takes several minutes, depending on the number of activated
room groups. During the search process, the sandglass symbol
appears on the
"Device list" line.
When the search process is finished, a tick will appear
.
Now, the number of identified devices is valid.
If the number of devices are not identical with the number given in the planning
documentation, the connection to the individual room controllers is to be checked.
The "Update" command is used to search the plant for devices that have not yet
been detected.
This command is to be executed when devices have been added to the plant at a
later point in time, for example.
The "Delete" command deletes the device list. Supervision does not occur when
the list is empty and the number of identified devices is 0 accordingly.
