Configuration of the signals
1 2 3
1 Signal number. Each line of the table corresponds to a signal. Signals cannot be added or deleted, because
the signals available are fixed and can only be enabled or disabled. Serves only to number the rows.
2 Device no. in the list of devices of the Connection tab to which the signal belongs. Not editable.
3 Code. Identifies each signal. A code appears beside each name to identify it. Section 1.1 gives the meaning
of each signal. The right button makes a contextual menu appear showing all the possible codes. Not editable.
4 Long description of the signal. This description corresponds to the Code. It indicates if the signal is read R and/or write
W.
5 EIS The KNX EIS type (Data point), the format in which the signal value is transmitted. The right button makes
a contextual menu appear showing all the possible types. Not editable.
6 Group. It is the KNX group with which the signal is associated and to which reading (R), writing (W),
transmission (T) and updating (U) are applied. It is the sending group. Editable.
7 Listening addresses. KNX group addresses that will act on the signal, apart from the Group.
8 R. Read. If enabled, it will permit read messages from this Group.
9 W. Write. If enabled, it will permit write messages from this Group.
10 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.
11 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 first listening address will be used.
12 Enable. Permits the use of each signal to be enabled or not. Enabled signals must have a valid KNX configuration.
Only signals that are going to be used from KNX should be enabled.
