        Hello BACnet Lighting Working Group!

        BACnet - Lighting Applications Working Group
        Meeting Minutes
        Norfolk, Virginia

        Participants - Affiliation
        Steve Karg - Lithonia Lighting
        Robert Hick - Leviton Lighting
        David Fisher - Polarsoft
        Steve Treado - NIST
        Steve Jurasek - Applied Control Specialists
        Dick Chipchak - Applied Control Specialists

        The meeting was called to order at 8:30am. A timekeeper (Steve
        Treado) and a scribe (Robert Hick) were assigned. Dick Chipchak was
        volunteered to track the non-agenda items. The previous meeting
        minutes were reviewed and approved. The meeting agenda was reviewed .
        Steve Karg noted that he added "A color property in the Lighting
        Output Object" to the agenda. Agenda was approved as ammended.

        Liason Reports
        Robert Hick reported on NEMA DALI activity:

        NEMA Joint Sections Committee on DALI has received several comments
        back on NEMA 243 DALI Protocol and is currently discussing and
        integrating changes into the document.

        The NEMA Lighting Controls Section is meeting 9/28 . One item on the
        agenda will be to approve funding for the Verification and
        Demonstration of DALI 243. It is expected to pass and has strong
        support from the controls and ballast communities.

        Initial response indicates COMEX Project Team members may not
        integrate NEMA 243 into IEC 62386. NEMA is expected to continue to
        promote NEMA 243 for US and North America.

        Robert also noted that Zigbee is now showing up in commercial ballasts
        and control devices as a wireless protocol.

        LA-WG proposal discussion:

        DMF032-4/5 WriteGroup Service

        David Fisher described changes he had made to this proposal,

        Corrected title.
        Added GroupChannelGeneralValue to encompass additional data types if
        desired and still preserve the simplicity and efficiency of the
        smaller data types. Null value is relinquish.
        Add optional property for Transition Time.

        It was moved that this proposal be sent up to the SSPC for
        consideration, the motion was carried. A brief discussion ensued about
        the status of the other proposals, it was noted that most were on the
        docket for the next SSPC meeting.

        Room Combining

        Robert Hick presented a paper describing room combining and examples
        for using the newly proposed WriteGroup and WriteGroupMode services.

        David asked if BACnet devices needed to have visibility to the
        contents of a "preset". It was decided to hold this
        discussion until

        A discussion about dynamic group membership and means to accomplish it
        It was decided that a property should be added to the control group
        object to read and write the group membership. It was decided that
        and array would be the best choice.

        David Fisher agreed to try to make these revisions to both DMF-30 and
        DMF-32 prior to the SSPC meeting discussion.

        A color property in the Lighting Output Object

        Steve Karg presented a case whereby there was a need to add color
        control to the light object. Steve's example was a fixture with a
        variable color ring.

        Steve presented information on how color control is done on PC's.
        Three 8bit values representing Red, Green, and Blue, appeared to be
        the most popular system. It was suggested the we incorporate an RGB
        value property into the light object proposal DMF-011. It was decided
        that luminescence remain a separate property.

        A discussion ensued concerning the meaning of RGB and how it relates
        to chromaticity, it was decided that this should be a local matter.

        A motion was made and seconded to add this property to the Lighting
        Object. Motion was carried. David Fisher will add this to the
        Lighting Output Object.

        Visibility of members of a preset.

        A discussion ensued concerning whether BACnet should have visibility
        of lighting preset contents. It was decided that the WriteGroupMode
        service provided a simple "mode" number to select a preset,
        further defining mode to be a preset with specific contents may harm
        the flexibility of this service for non-lighting applications.

        Next meeting
        It was decided that the LAWG had submitted proposed solutions to
        BACnet lighing requirements and no new issues have been discovered. A
        future meeting would be held only if new issues were identified or
        further work on current proposal was needed. Tentative date for next
        meeting opportunity would be January 14-18 in Chicago. More details
        will be posted to the mailing list by Steve Karg as they become
