Denition of signals
Each signal from the external system uses the following KNX properties:
Property Description
Signal Signal description Only for information. Permits a signal to be identied easily.
EIS (DataPoint)
The type of KNX data item used to express the value of the signal. Depends on the type of external system
signal in each case. In some integrations it can be selected, while in others it is xed, given the intrinsic
nature of signals.
Group
The KNX group with which the signal is associated. It is also the group to which reading (R), writing (W),
transmission (T) and updating (U) are applied. It is the sending group.
Listening ad-
dresses
Addresses that will act on the signal apart from the Group.
R Read If enabled, it will permit read messages from this Group.
W Write. If enabled, it will permit write messages from this Group.
T
Transmission. If enabled, when the value of the signal changes due to a change in the value of the external
system, a write message will be sent from the Group to the KNX bus.
U
Update. If enabled, on starting KNX001 or after the KNX bus falls over, read messages will be sent
to the KNX bus of the sending group. The value received will be sent to the external system as if it had been
received by written message. If U2 is selected, instead of using the address of the sending group,
the rst listening address will be used.
Enable
If enabled, the signal is enabled in IntesiBox, otherwise it behaves as if the signal has not been dened
or does not exist. Permits signals to be disabled, without having to delete them.
