LOYTEC L-DALI - Node Object #0000; Real-Time Keeper Object #3300; Calendar Object #0006

L-DALI User Manual 236 LOYTEC
Version 5.2 LOYTEC electronics GmbH
The interface configuration can be chosen via the Project Settings in the Configurator
Software (see Section 7.16.2).
8.2.1 Node Object #0000
The L-DALI provides a node object conforming to the LONMARK guidelines for each DALI
channel.
 The Node Object accepts the following commands via nviRequest: RQ_NORMAL,
RQ_UPDATE_STATUS, RQ_REPORT_MASK, RQ_ENABLE, RQ_DISABLE,
RQ_UPDATE_ALARM, RQ_CLEAR_ALARM, RQ_RESET, RQ_CLEAR_RESET
 LONMARK alarming is supported via nvoAlarm (SNVT_alarm) and nvoAlarm_2
(SNVT_alarm_2). This allows devices supporting the LONMARK alarm notifier profile
to receive alarms generated by the L-DALI and react with a defined action (e.g., send
an email). By supporting both alarm SNVTs, SNVT_alarm and SNVT_alarm_2, legacy
and state-of-the-art alarm handling is supported.
 nviDateEvent (SNVT_date_event), nvoDateResync (SNVT_switch): If not bound, the
local calendar is used. If a global calendar shall be used, both of these NVs must be
bound to the respective NVs of the global calendar object.
 nviTimeSet (SNVT_time_stamp): When writing to this NV, the system is set, if the
configure time-source is “LONMARK” or “Auto” (see Section 5.2.11). The time value is
interpreted as local time.
 nvoSystemTemp (SNVT_temp): This NV can be used to poll the system temperature of
the L-DALI. It does not send updates and must be polled.
 nvoSupplyVolt (SNVT_volt): This NV can be used to poll the supply voltage of the
L-DALI. It does not send updates and must be polled.
 nvoIpAddress (SNVT_str_asc): This NV can be used to poll the IP address of the
L-DALI. It does not send updates.
 nciEarthPos (SNVT_earth_pos): This configuration property can be used to set the
earth position of the L-DALI. It has been implemented as an NV to make other devices
send that configuration to the L-DALI over the network (e.g., from a GPS device).
This object type cannot be disabled.
8.2.2 Real-Time Keeper Object #3300
The L-DALI includes one standard LONMARK real-time keeper object for each DALI
channel. The Real-Time Keeper Object is used to synchronize the system time of multiple
LONMARK compliant devices.
The object has the following network variables:
 nvoTimeDate (SNVT_time_stamp): Propagates the devices current system time and
date (local time). It is typically bound to the nviTimeSet input network variable of the
node objects of the LONMARK compliant devices, which are synchronized with the
system time of the L-DALI. The update rate of the nvoTimeDate can be configured
using the configuration property SCPTupdateRate (default every 60 seconds).
This object type cannot be disabled.
8.2.3 Calendar Object #0006
The L-DALI includes one standard LONMARK calendar object for each DALI channel.
This object type cannot be disabled.
