Initial Value |
Values/Options/Range |
Description |
|---|---|---|---|---|
|
Alarm Event State |
C,W |
True |
False True |

Applies to BI, BO, MI, and MO objects only. |
Limits or modifies the mapping to the field states/commands used by the object. This string refers to one of the conversion identifiers in the CommandStatusMap.xml file. |
|
|

|
Device Class |

Device Subclass |
Maximum Length = 40 Category = Default |
Indicates the device subclass usage of a device. The LonWorks network server is responsible for populating the Program ID (which includes the Manufacturer, Device Class, Device Subclass, Transceiver, and Model). If no standard Program ID exists, the value is n/a. |

|
Disable Automatic Alarming |
C,W |
False |
False True |
Specifies whether automatic online/offline device event reporting is disabled (True) or enabled (False). This attribute only applies to the device and not to the device’s mapped objects. Devices with the Disable Automatic Alarming attribute set to True suppress the alarm event but still indicate they are offline in the navigation tree with a red X. Alarm extensions are not affected by this attribute. |
|

|
|
DSN 2 |
C |
Maximum Length = 30 Category = Default |
Displays the native LonWorks network address (in Domain-Subnet-Node format). DSNs must be unique on the LonWorks network. DSN 1 is required, but DSN 2 can be left blank. Use the format xx/xx/xx. |
|
|

Indicates whether polling is enabled or disabled when the Engine is in complete control of this item. |
|
|
Field Units |
C,W |
DegF |
Uses Unit Set (Set 869). This attribute is for AI and AO objects only. |
Lists the engineering units that pertain to the LonWorks network data. This attribute is for AI and AO objects only. |
|
File Filter |
W |
Maximum Length = 40 Category = Default |
Lists the types of files that can be used as file extensions to the LON Integration object. The list includes:
File Filter can be edited for alternate languages and must be in the xxx file format. |
|
|
Interface Value |
Indicates the current value from the hardware interface. The Interface Value updates when the hardware is read or when the hardware’s current value changes. |
|||
|
LNS Database Name |
C,W |
Maximum Length = 30 Category = Default |
Displays the name of the LNS database used to build the LonWorks network trunk. |
|
|
Location Label |
Maximum Length = 30 Category = Default |
Describes the location of the controller. |
||
|

Applies to AO, BO, and MO objects only. |
Indicates that an HOA switch on the referenced item is set to Hand or Off. |
||
|
Manufacturer |
Maximum Length = 40 Category = Default |
Indicates the manufacturer of a device. The LonWorks network server is responsible for populating the Program ID (which includes the Manufacturer, Device Class, Device Subclass, Transceiver, and Model). If no standard Program ID exists, the value is n/a. |
||
|
Message Retry Count |
C,W |
1 |
Range = 0–15 |
Indicates the number of retry attempts to use when communicating with this controller. |
|
Model |
0 |
Indicates the model number of a device. The LonWorks network server is responsible for populating the Program ID (which includes the Manufacturer, Device Class, Device Subclass, Transceiver, and Model). If no standard Program ID exists, the value is n/a. |
||
|
Neuron ID |
Fixed Length = 6 Category = Default |
Displays the Neuron ID of the local LonWorks network interface board or contains the Neuron ID of the remote LonWorks network controller. The Neuron ID must be unique to the LonWorks network. |
||
|

Indicates the Priority (1–3) at which to poll this item. |
||
|
Program ID |
