The Node Object accepts the following commands via

RQ_NORMAL
o
RQ_UPDATE_STATUS
o
RQ_REPORT_MASK
o
RQ_ENABLE
o
RQ_DISABLE
o
RQ_UPDATE_ALARM
o
RQ_CLEAR_ALARM
LonMark alarming is supported via
nvoAlarm
(SNVT_alarm) and
nvoAlarm_2
(SNVT_alarm_2). This allows devices supporting the LonMark alarm notifier profile
(e.g. i.LON 100) to receive alarms generated by the L-IP Redundant 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.
The network variable
nvoSupplyVolt
(SNVT_volt) holds the current supply voltage of
the L-IP Redundant, while
nvoSystemTemp
(SNVT_temp) contains the current internal
temperature. With these two network variables a simple health monitoring can be
performed.
The statistic counters of all Channel Monitor objects (see Section 9.7.5) can be reset by
setting the network variable
nviClearStat
(SNVT_switch) to {100, ON} and back to {0,
OFF}.
The network variable
nvoUpTime
(SNVT_elapsed_tm) gives the time elapsed since the
L-IP was (re-)booted.
9.7.2 Bus Loop Monitor Object
Figure 134 shows the Bus Loop Monitor Object functional block. This functional block is
responsible for the bus loop monitoring (see Section 9.2.1). It has the following network
variables:
