o
The CRC Error Rate during the last statistic interval (
nvoIvalCrcErr
)
exceeded the limit defined by the
SCPThighLimit1
(default 5 %) OR
o
The Missed Packets Rate during the last statistic interval (
nvoIvalMissed
) was
not zero OR
o
The Missed Preamble Rate during the last statistic interval (
nvoIvalMisPre
)
exceeded the limit defined by the
SCPThighLimit1
(default switched off).
If an overload is detected, the network variable is set to {100, ON}. If no error
occurred, it is set to {0, OFF}.
nvoChnlAlarmRat (
SNVT_lev_cont
): Ratio between statistic intervals during which the
channel was in overload alarm condition and intervals during which the channel was
not in overload alarm condition since power-up or since the statistics for this port
where reset.
In addition, each channel monitor object has the following SCPTs:
SCPTifaceDesc: This configuration property contains a human-readable name of the
monitored port. Possible values on the device are ―CEA-709‖, ―IP‖, or ―inactive‖.
SCPTmaxSndT: Defines how often output NVs are transmitted. Exceptions are
nvoPort, and nvoElapsedTime, which are polled-only.
13.2.5 Calendar Object
When the scheduler objects are enabled in the project settings, the device includes the
standard L
ON
M
ARK
calendar object.
13.2.6 Scheduler Object
When the scheduler objects are enabled in the project settings, the device includes the
configured number of standard L
ON
M
ARK
scheduler objects.
13.2.7 Clients Object
When the remote AST object feature is enabled in the project settings, the device includes a
proprietary object, which is a container for network variables required to implement the
remote object features.
For remote schedulers and calendars,
nviSchedLink
and
nviCalLink
NVs are created. For
alarm clients, nviAlarm_2 NVs are created.
13.2.8 Gateway/PLC Objects
The device contains eight proprietary Gateway objects. These are containers for all NVs
which are configured on the device‘s CEA-709 port. They are intended for grouping NVs.
When static NVs are created, they can be assigned to any of the eight gateway blocks.
When creating dynamic NVs in the LNS-based tool, the NVs should be added to the
gateway blocks.
13.3 BACnet Interface
13.3.1 Device Object
The BACnet interface provides one device object as shown in Table 15.
