(AX-3.2 and later only) This button in the Bacnet Ws Device Manager allows you to backup the selected device’s configuration, as one or more “restorable” files on the BACnet Supervisor PC.
If needed, you can use the Restore function later to reinstall this backup.
The target device must support the BACnet DM-BR-B BIBB, as part of the B-BC device profile conformance. Both the BACnet specification
135-2008 and addendum 135-2008n are supported. In addition, the device may require a password before it initiates a backup
or a restore. Otherwise, a backup or restore job will immediately fail, showing the associated reason in the job log details.
For example, you may see “Unrecognized Service” or “Security: Password Failure”.
When you click , the standard Directory Chooser appears, in which you specify the target directory for the backup file(s). If needed, use the “new folder” control 
, as was done in the example shown in Figure B.9 to make a “Bacnet” folder under the system “backups” folder.
After you choose the target directory, the Backup Device dialog appears, as shown in Figure B.10.
Configuration fields in this dialog include the following:
-
Base Directory
Reflects the ord for the local target directory, as previously chosen in the Directory Chooser. If needed, you can modify it using file ord syntax.
-
Device Directory Name
This specifies the subdirectory that will be made under the base directory for the device’s backup file(s). This defaults to
<BacnetWsDeviceName><YYYYMMDD_HHMM>, where the last portion is a timestamp that reflects when the backup was initiated. If desired, you can modify. -
Password
Some devices may require a password to initiate a backup and/or a restore. If a device requires a password, you may enter it here.
When you click , the backup request is sent to the device. A Backup job is started, and as shown in Figure B.11 you can click on the job log control near the top of the manager to see the progress of the backup.
When the job completes, it will post a success or failed status. A successful backup has the specified device subdirectory under the target base directory, containing one or more backup files for the device.
An invalid backup job typically fails immediately. However, a valid backup job may take several minutes to complete, depending
on the implementation in the target BACnet device. Typically, the device executes some “preparation routine” first, before
assembling and sending the backup files. In the case of AX-3.2 or higher stations running the Bacnet driver, there is a set
server routine as well as associated properties, found in the LocalBacnetDevice of the BacnetNetwork. For more details, see
Local Device backup and restore properties.
