hager"DALI Gateway C00Cx2" softwareFunctional description4.2.4 Functional description4.2.4.1 Application basicsDALIThe DALI Gateway represents the interface between a KNX/EIB building installation and a digital DALI(Digital Addressable Lighting Interface) lighting system. Normally, all DALI systems are room-orientedand deal with the high demands on functional light management in, for example, offices, training andconference rooms. Often, these applications make it necessary to incorporate the room-oriented DALIsystem also into the KNX/EIB facility management across buildings. That makes it possible not only tocontrol the DALI lighting system via the sensor components of the KNX/EIB but also to incorporate theshutter, heating and air conditioning systems already existent in the buildings into the lightmanagement.A DALI system can address a maximum of 64 devices. The Gateway itself does not count as a device.The DALI Gateway offers 32 KNX/EIB controllable groups that are parameterized in the ETS 3 similarto a dimming actuator channel. There are several communication objects available at the bus thatpermit, among other things, the switching, the dimming, the setting of brightness values or the time orscene control of a group. During the DALI commissioning, the DALI devices (max. of 64) will beoptionally assigned one or several groups of the Gateway (cf. figure 5 on the following page). It is thegroup assignment that makes it possible to control the DALI devices individually (individual assignment– only one device in the group) or collectively (multiple assignment – several devices in a group) via theKNX/EIB.A multiple assignment of DALI devices is possible for the groups 1...16 of the DALI Gateway. In thiscase the addressing takes place at the DALI via group addresses that the DALI Gateway configures“hidden” to the user. The DALI Gateway handles them independently. During the DALI commissioning,all affected devices will be automatically programmed.The groups 17...32 accept only individual assignments. Each group can be assigned only one DALIdevice. In this case, the DALI addressing takes place via an internally specified individual address.Only one device can be uniquely addressed via this individual address. This individual address will alsobe automatically assigned by the DALI Gateway during the DALI commissioning.The DALI commissioning takes place entirely via the plug-in embedded in the ETS 3 via the KNX/EIBbus line. No additional tool and no special programming link is required.The commissioning of the DALI devices as well as the DALI configuration or the DALI addressing takesplace fully automatic via the plug-in and the DALI Gateway. Only the assignment between the DALIdevice and the group must be carried out ‘manually’ in the commissioning environment of the plug-in.Different test or detection functions (separate switching on, switching off or blink function) available inthe plug-in make it also considerably easier to commission the different DALI devices.Seite 27 von 130
