The Bacnet Aws Device Manager (Figure A.1) is the default view for the BacnetAwsNetwork (and any BacnetAwsDeviceFolder), and provides all the same features as the regular Bacnet Device Manager.
You discover BACnet devices in this view the same as in the Bacnet Device Manager view. For details, see About Bacnet Device Find Parameters. When doing a discover, the Add dialog provides the same parameters for adding BacnetAwsDevices as for BacnetDevices. See BacnetDevice properties.
All devices are represented as BacnetAwsDevices in a BacnetAwsNetwork. Nearly identical to a BacnetDevice, a BacnetAwsDevice differs by its device extensions “Trend Logs”
and “Config”, and the default views on those extensions.
The bottom row of buttons in the Bacnet Aws Device Manager include two that are in the standard Bacnet Device Manager: and . For more details, see Timesynch (TSynch) function and Device ID function.
Several additional buttons are in the bottom row in the Bacnet Aws Device Manager. These correspond to additional functions that can be performed on BacnetAwsDevices.
These additional buttons available in the Bacnet Aws Device Manager are:
-
— See Event Information.
-
— See Enrollment Summary.
-
— See Communication Control.
-
— See Reinitialize Device.
-
— See Backup Device.
-
— See Restore Device.
(Also in Bacnet Ows Device Manager) This button in the Bacnet Aws Device Manager retrieves event information from the selected device, requesting all outstanding events from the BACnet device. The purpose
of this feature is that if Niagara somehow missed receiving an event, you can still retrieve and acknowledge this event using
the Event Information service. For example, the Niagara station may not have been running at the time the original event occurred.
If the GetEventInformation service is supported, this will be used to retrieve events. The events retrieved in this manner contain enough information to generate a valid acknowledgment to the remote device. These event summaries will be propagated to the Niagara Alarm Service through the alarm class assigned in the eventSummaryAlarmClass property of the Event Handler.
Event Handler configuration is contained within the Server layer configuration of the network’s BacnetComm container, as shown in Figure A.2.
If the GetEventInformation service is not supported, but the GetAlarmSummary service is supported, the events will be retrieved
using GetAlarmSummary. The GetAlarmSummary service retrieves only events with a Notify_Type of “alarm”, so events with a Notify_Type of “event” are not retrieved.
The GetAlarmSummary service has been deprecated by the BACnet Committee, and manufacturers should no longer be making devices that use it. Typically, this is seen only in
older devices.
Event summaries retrieved using GetAlarmSummary do not have enough information to generate a valid acknowledgment, so they are not propagated to the Niagara Alarm Service. In this case, a dialog box is presented to the user, such as shown in Figure A.3.
(Also in Bacnet Ows Device Manager) This button in the Bacnet Aws Device Manager retrieves a summary of all objects within the device that match a set of filter criteria that you define. When you click
the Enrollment Summary button, a filter configuration dialog box is displayed, as shown in Figure A.4.
Here you configure the various options to define the specific types of objects you wish to locate, and then click . The device is queried for a list of objects that meet the specified filter criteria, and the result is displayed in a dialog box, as shown in Figure A.5.
Filter options include the following:
-
Acknowledgement
Filter on points that are acknowledged, or unacknowledged, or leave the filter open to all points.
-
Enrollment
Filter on only event mechanisms that have a specific recipient, definable either by device id or by device address.
-
Event State
Specify a particular event state, to restrict the request to include only points that are currently in a specific event state.
-
Event Type
Restrict the filter to objects that use a particular event type algorithm.
-
Priority
Choose to only include objects where the priority of the last transition is within certain bounds.
-
Notification Class
Include only objects and event mechanisms where the notification class used to route the event notifications is equal to a specific number.
This button in the Bacnet Aws Device Manager allows you to control a device’s ability to generate traffic on the network. This could be useful in a diagnostic situation,
where you want to temporarily eliminate all traffic except from a single device. Or you may have a faulty device that is sending
extraneous data, and you wish to “silence it” until you can identify the cause of the problem. When you click this button,
a dialog box appears which allows you to configure the request, as shown in Figure A.6.
Configuration options include the following:
-
Enable Disable
You can choose to Enable or Disable the device from sending any BACnet requests. You can also choose to “Disable Initiation,” which allows the device to respond to BACnet requests, while being prevented from initiating any requests of its own. Note that the sending of a single I-Am request is allowed if a Who-Is request that matches the device’s device id is received.
-
Duration
You can configure the length of time for which communications will be disabled, after which the communications will automatically be re-enabled for the device.
-
Password
Some devices may require a password to disable their communications. If a device requires a password, you may enter it here.
When you click , a request to control the communication is sent to the device. The result is displayed in a dialog box, with either a success message, or a message including the error returned by the device.
This button in the Bacnet Aws Device Manager allows you to restart a device. In the popup dialog (Figure A.7), you may choose either “Cold Start” or “Warm Start.”
The specific meaning of terms Cold Start and Warm Start is left up to the device’s manufacturer to define, so make sure you
understand exactly what each procedure entails for the device in question.
As shown above, this dialog has two fields:
-
Reinitialize Command
Select either Warm Start (default) or Cold Start (see Note above).
-
Password
Enter the password required by the device to invoke this command. Some devices may not require a password, so if you do not enter anything, no password is sent to the device.
When you click , the reinitialize request is sent to the device. The result is displayed in a dialog box, as either a success or failure.
This button in the Bacnet Aws Device Manager allows you to backup the selected device’s configuration, as one or more “restorable” files on the BACnet AWS 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 A.8 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 A.9.
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
<BacnetAwsDeviceName><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 A.9 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 JACE stations running the Bacnet driver, there is a set “server side”
routine as well as associated properties, found in the LocalBacnetDevice of the BacnetNetwork. For more details, see Local Device backup and restore properties.
This button in the Bacnet Aws Device Manager allows you to restore a previous backup to the selected device, where a backup is one or more “restorable” files saved on
the BACnet AWS Supervisor PC. See Backup Device.
The target device must support the BACnet DM-BR-B BIBB, as part of the B-BC device profile conformance. Both BACnet specification
addendums 135-2008 and 135-2008n are supported. In addition, you may require a device password to have it initiate 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 navigate to the directory that contains the backup file(s), as shown in Figure A.11.
After you choose the source directory, the Restore Device dialog appears, as shown in Figure A.12.
Configuration fields in this dialog include the following:
-
Directory
Reflects the ord for the local source directory, as previously chosen in the Directory Chooser. If needed, you can modify it using file ord syntax.
-
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 restore backup request is sent to the device. A Restore job is started, and as shown in Figure A.13 you can click on the job log control near the top of the manager to see the job progress.
When the job completes, it will post a success or failed status. Successful restores will install the backup file(s) found in the source directory, and typically re-initialize (reboot) the device.
An invalid restore job typically fails immediately. However, a valid restore 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
accepting the backup files. In the case of JACE stations running the Bacnet driver, there is a set “server side” routine as
well as associated properties, found in the LocalBacnetDevice of the BacnetNetwork. For more details, see About backup and restore operations.
