ANNEX II: COMMUNICATION OBJECTS
“Functional range
” shows the values that, with independence of any other values permitted by the bus according to the object size, may be of any use or have a particular meaning because
of the specifications or restrictions from both the KNX standard or the application program itself.
“
1
st
boot
” shows the cases where an object is assigned a certain value by the application program after a device download or a full reset. In case the value of such assignment can be
parameterised,
√
is shown in column “
P
”. Objects showing a hyphen (-) are not assigned a particular value and therefore can be assumed to be initialised with the value “0” or with the
corresponding updated value in case they depend on an external element (sensors, etc.). Moreover, if the object is sent (or is there an option to send it) to the bus (write or read requests)
after a download or a device reset from ETS, the marks
(W)
or
®
will be shown, respectively for transmissions or read requests.
“
Reboot
” shows the cases where an object is assigned a certain value by the application program after a bus power failure. In case the value of such assignment can be parameterised,
√
is
shown in column “
P
”. Objects showing a hyphen (-) are not assigned a particular value and therefore can be assumed to maintain their previous value after the failure or with the
corresponding updated value in case they depend on external elements (sensors, etc.). Moreover, if the object is sent (or is there an option to send it) to the bus (write or read requests) after
a bus failure, the marks
(W)
or
(R)
will be shown, respectively for transmissions or read requests.
