Local Device
Figure 163. Local Bacnet Ows Device properties
You access local device properties by expanding in the Nav tree and double-clicking the Local Device node.
The Local Bacnet Aws Device has all the same properties and components of a regular BACnet Local Device.
In addition to the common properties (Status and Fault Cause), this component has these properties.
| Property | Value | Description |
|---|---|---|
| Object Id | drop-down list and number (from 0 to 4194302) |
Identifies each device and component by the type of entity (
Object Id) combined with a unique Instance Number.
For devices (controllers, instruments, meters, etc.), |
| System Status | read-only |
Reports the current condition of the network.
|
| Vendor Name | read-only |
Reports the vendor number.
|
| Vendor Id | read-only |
Reports an identifier for the vendor’s device.
|
| Model Name | read-only |
Reports the manufacturer’s model name for the device.
|
| Firmware Revision | read-only |
Reports the version of the device firmware.
|
| Application Software Version | read-only |
Reports the version of the manufacturer’s software running on the device.
|
| Location | text (defaults to unknown) |
Describes the device location.
|
| Description | text |
Provides additional information, which could include the camera’s geographical location or other unique information.
|
| Device Uuid (Universally Unique IDentifier) | read-only |
Uniquely identifies the object in the system.
When you upgrade a BACnet driver or drop in a BACnet network from the palette, the driver automatically sets this 128–bit universally unique identifier (UUID) to a random value. You should not need to change this property. The driver uses it behind the scenes. |
| Protocol Version | read-only |
Displays the version number of the BACnet protocol.
|
| Protocol Revision | read-only |
Displays the current BACnet protocol level.
|
| Protocol Services Supported | check box list |
Expands to identify all the available BACnet device services supported by this version of
|
| Protocol Object Types Supported | check box list |
Expands to identify all the available BACnet object types supported by this version of
|
| Max A P D U Length Accepted | read-only |
Reports the number of points per poll or APDU (Application Protocol Data Units).
|
| Segmentation Supported | read-only |
Indicates the type of message segmentation the device supports. If a message exceeds the Max Segment Accepted length, the
device must be able to break it into segments or part of the message is lost.
|
| Max Segments Accepted | read-only |
For a single segment, defines the number of characters the device supports.
|
| Apdu Segment Timeout | milliseconds (defaults to 2000 ms) |
Defines the time the system waits before retransmitting an APDU segment. This property is only relevant if devices are doing
segmentation.
Works for both client and server operations. For a small IP-based network, an optimal setting may be: 5000 ms. |
| Apdu Timeout | milliseconds (defaults to 3000 ms) |
Defines how long the system waits before retransmitting an APDU that requires acknowledgment, for which no acknowledgement
has been received.
Works for both client and server operations. Large, routed networks may require higher timeouts. |
| Number of Apdu Retries | number (defaults to 3) |
Defines the maximum number APDU retransmissions.
Works for both client and server operations. For a small IP-based network, an optimal setting may be: 1 retry. |
| Database Revision | read-only |
Reports the version of the database.
|
| Last Restore Time | read-only |
Reports when a backup .dist file was last restored by a remote BACnet Workstation client. If never, all timestamp properties
show asterisks (*).
|
| Backup Failure Timeout | time range (defaults to 3 minutes) |
Specifies the time the server device must wait before deciding that the client has given up, and can leave backup/restore
mode. The client writes this to the server prior to beginning the backup/restore procedure.
|
| Backup Preparation Time | time range (defaults to 1 minute) |
Reports the time taken, after receiving a restore request, to gracefully shut down the station and close files before beginning
the backup.
|
| Restore Preparation Time |
Reports the time taken, after receiving a restore request, to gracefully shut down the station and close files before beginning
the dist file installation.
|
|
| Restore Completion Time | timestamp (defaults to 3 minutes) |
Reports the time taken, after completing a dist file install from a restore, for the station to restart and become responsive.
|
| Backup and Restore State | read-only |
Shows the current status of any backup or restore operation. The driver displays Idle when no operation is active. This changes to Preparing for backup and so forth.
|
| Character Set | drop-down list (defaults to Ansi C3_4)
|
Defines the character set supported, with other selections: IBM/Microsoft DBCS, JIS C 6226, ISO 10646 (UCS-4), ISO 10646 (UCS-2),
ISO 8859-1, and Unknown.
|
| Enumeration List | sets of enum facets |
Lists the BACnet properties that can be exported to configure data exchange. This Extensible Enum List provides access to
each property's configuration facets.
|
| Export Table | Bacnet Export Manager |
Provides the special manager views to associate devices and points (local objects) with BACnet objects (exported objects).
You discover objects or add them using the New button.
The Bacnet Export Manager (plugin) topic documents this table. |
| Time Synchronization Recipients | Bacnet List Of |
Define the devices to receive time synchronization messages from the driver. This list of recipients is for periodic time
synchronization messages. You add to and remove entries from this list using the right-click addElement and removeElement
actions. Entries in this list are BacnetRecipients. They can be either a device object identifier, or a BACnet address.
|
| Time Synchronization Interval | timestamp (defaults to 24 hours) |
Configures how frequently the software sends the time synchronization messages.
|
| Align Intervals | true (defaults) or false |
Turns on and off the configuration of standard synchronization intervals for controller stations.
|
| Interval Offset | minutes |
Specifies an offset from the beginning of the interval at which to send the periodic time synchronization messages. If
Align Interval is false, the driver ignores this property.
|
| Utc Time Synchronization Recipients | Bacnet List Of |
Lists the recipients for periodic Time Synchronization messages. You can add and remove entries to this list using the right-click
addElement and removeElement actions. Entries in this list are BacnetRecipients. They can be either a device object identifier,
or a BACnet address.
|
| Last Restart Reason | drop-down list |
Reports the reason for the last restart.
|
| Time of Device Restart | date and time |
Specifies the time of device restart based on the time of day (Time), a sequence number (SeqNum) or a date and time (DateTime).
|
| Restart Notification Recipients | Bacnet List Of |
Defines the alarm recipients to receive notification that the station restarted.
