BACDESK Features
BACdesk is designed as a tool to support both service providers and end users during the planning, test and project phase as well as during the ongoing operation of technical systems using BACnet.
Visualization, monitoring and analysis of BACnet networks and devices are basic functional features of the application. The connection to the BACnet network is made by default via TCP/IP, the communication parameters are adjustable. If a router is used, however, communication with MS/TP devices is also possible. BACdesk can be operated like a simple BACnet device in a network, but can also function as a BBMD or be attached to an existing BBMD as a foreign device. Furthermore, BACdesk offers functions for logging, analysis, validation and for performing conformance tests for plant operators, planners or project engineers.
BACdesk complies with the B-AWS (BACnet Advanced Workstation) profile according to ANSI/ASHRAE Standard 135-2012 (Revision 18) as well as the AMEV MBE-B profile. The supported services and objects as well as the further specification can be taken from the PICS. A short overview of most of the function blocks can be found in the following sections.
SUPPORTED SERVICES (BRIEF OVERVIEW)
On the device or object level, almost all BACnet services can be called up or visualized. These include among others:
- Device search (Who-Is/Who-Has/I-Am/I-Have)
- Reading and writing values (Read-/WriteProperty(Multiple))
- Editing lists (Add-/RemoveListElement)
- Reading of memories (ReadRange)
- Notification of alarms or value changes (Cov-/EventNotification)
- Acknowledgement of events (AcknowledgeAlarm)
- Events and alarms (GetAlarmSummary/GetEventSummary/GetEventInformation)
- Create or delete objects (Create/DeleteObject)
- Time synchronization ((Utc)TimeSynchronization)
- Communication control etc. (DeviceCommunicationControl)
- Cold/Warm start, Backup&Restore (Reinitialize Device)
- Reading of file contents (Read/WriteFile)
- Sending and receiving text messages (TextMessage)
All implemented services can be called or processed in any specified variant. The exact list of supported services can be taken from the PICS.
BROWSER/VISUALIZATION
Devices available in the network can be detected and integrated by means of various search and filter mechanisms. In case of a missing BBMD structure this is also possible via unicast messages. All objects and properties of these devices defined in the currently supported revision as well as user-defined objects and properties can be visualized, read and written if the user has the appropriate authorization. Almost all BACdesk views can be configured, filtered and exported, so that saving the current display is possible at any time and speedy work (e.g. through mass operations such as changing several setpoints simultaneously) is guaranteed.
For the visualization, different dialogs and views are available depending on the type for better readability and clarity. In addition, there are additional display options for certain object types. These include the following:
- TrendLog: Display of the contained data in diagram form
- TrendLogMultiple: Display of the contained data in diagram form (multi-track)
- EventLog: Display of the contained data records in table form
- StructuredView: Display of the structure in hierarchical form
- File: Display of the buffer contents in text form with selectable coding
VALUE MONITORING
- Quick monitoring - Properties can be monitored for change at any time in parallel to the current activity by means of a separate window.
- Groups - Objects or properties can be combined in persistent groups for better monitoring or operation. The group with its contained properties is stored persistently.
- Groups (dynamic) - Objects or properties can be combined dynamically using predefined and freely combinable filters for better monitoring or operation. The group with its configuration is stored persistently.
COMPARATIVE SNAPSHOTS
ANALYSIS AND VALIDATION
- Recording of data traffic: The data traffic running over the various network interfaces can be specifically recorded in files and evaluated with common analysis software (e.g. Wireshark).
- Communication statistics: A window keeps the user informed at any time about the type and number of incoming and outgoing BACnet telegrams per device or in the entire network.
- Validation of object names: The names of objects can be automatically subjected to a check.
- Test for COV(-P) support: Objects and properties can be automatically tested for support of the COV or COV-P service.
- Display of unsupported properties: In object views, properties not supported by the respective object can be made visible and highlighted in color.
- Automated unit tests regarding performance, compatibility and project requirements.
