8.2.5.7 Status Monitoring
The L-DALI monitors the DALI lamps and reports any failure in the output network
variables
nvoGPFailure
(group object) and
nvoCHFailure
(channel object).
A lamp failure is reported if either
bus power for the related DALI channel fails,
the DALI ballast is not reachable via the DALI channel, or
the DALI ballast reports a failure (e.g. lamp failure) in its DALI status register.
The value of the network variable
nvoGPFailure
of the group object reflects the percentage
of failed ballasts in this group.
The value of the network variable
nvoCHFailure
of the channel object reflects the
percentage of failed ballasts in this channel.
The network variable
nvoLampFailure
of type SNVT_state_64 reports the status of the all
lamps in a channel. Each bit corresponds to the lamp with the same index. In case of a
failure the bit is set.
8.2.5.8 Statistics
The L-DALI reports the run hours and energy consumptions of the DALI lamps.
Run Hours
The L-DALI determines how long each DALI lamp was switched on. If a lamp is replaced
the run hours can be initialized via the configuration property
nciRunHrInit
of the lamp
object. To limit the number of network variables the run hours are reported not separately
for each lamp but for a whole group or channel.
The group object reports the maximum run hours of all lamps in the groups via the output
network variable
nvoGPRunHours
.
The channel object reports the maximum run hours of all lamps on the channel via the
output network variable
nvoCHRunHours
.
Energy Consumption
The L-DALI device can calculate the energy consumption of the DALI lamps. For that
purpose it needs to know the nominal power of all connected DALI lamps. If the
configuration property
nciNominalPwr
of the lamp object is set to 0 (AUTO), the L-DALI
tries to obtain the energy consumption from the DALI device. However, not all DALI
ballasts support this proprietary extension. In this case the
nciNominalPwr
has to be
configured with the nominal power of the ballast. The energy consumption can be initialized
via the configuration property
nciEnrgyCntInit
of the lamp object.
To reduce the number of network variables the energy consumption is reported not
separately for each lamp but for a whole group or channel. The group object reports the sum
of energy consumed by all lamps in the groups via the output network variable
nvoGPEnergyCnt
. Equally the network variable
nvoCHEnergyCnt
reports the sum of
energy consumed by all lamps on the channel.
