• 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
• L
ONMARK alarming is supported via nvoAlarm (SNVT_alarm) and nvoAlarm_2
(SNVT_alarm_2). This allows devices supporting the L
ONMARK alarm notifier profile
to receive alarms generated by the L-Gate 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.
7.2.3 Extended Node Object Interface
When any of the AST features is enabled in the project settings, the node object contains
some extensions.
• nviDateEvent (SNVT_time_stamp), nvoDateResync (SNVT_switch): These NVs are
part of the standard L
ONMARK node object, if schedulers are used. 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. The time
value is interpreted as local time.
• nvoSystemTemp (SNVT_temp): This NV can be used to poll the system temperature of
the L-Gate. 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-
Gate. 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-
Gate. It does not send updates.
