Chapter 5: Using the BACnet Service Tool Software76 TACSome Typical Use CasesThe BACnet Service Tool allows you to drill-down the heirachy tree of BACnet devices, view property values of objects and perform some of the administrative functions available on the Andover Continuum CyberStation product.The following sections provide some information and examples on what you can do with the Service Tool. These examples only represent a small sampling of the administrative actions you can perform.Simple and Complex PropertiesTo help you understand what you can do with the Service Tool, there is one simple statement to remember: The BACnet Service Tool allows you to edit simple properties, but not complex properties.A simple property is one that has a single value, while a complex property is one that has more than one value that can be changed. Of course, there are always execeptions to general rules. Within the Service Tool, there are two complex properties that you can change, event-enable and limit-enable. Exception: Two complex properties that can be editedevent-enable limit-enable
Chapter 5: Using the BACnet Service Tool SoftwareBACnet Service Tool User’s Guide 77The Event-enable property has two values, Event Transitions and Send. The limit-enable property also has two values, Limit-Enable and Value.This differs from a simple property, such as the out-of-service property, that only has one value that can be changed. SelectingPropertiesProperties are selected from the detailed view of an object and by double-clicking on the property, a PropertyView/Set dialog is displayed where you can change or just view the current setting and options.Double-Click property to display dialog
Chapter 5: Using the BACnet Service Tool Software78 TACProblems In some cases, property values are displayed in the dialog and even thought you can change the value and hit the Apply button, the value does not change in the table. In other cases, you may not be able to bring up the Property View/Set dialog after double-clicking on the property. This can occur for one of two reasons:zYour access privilege is not set high enough to change this property.zThe property value is set on the controller from CyberStation and cannot be changed using the Service Tool.If you encounter this situation, check your security level to see if you are authorized to change a property value, or consult with your system administrator.
Chapter 5: Using the BACnet Service Tool SoftwareBACnet Service Tool User’s Guide 79Adjusting a Temperature SetpointOne very typical example of using the Service Tool is to change or adjust a temperature setpoint. To adjust a temperature setpoint, perform the following steps:Step 1:From the Service Tool graphical interface, make sure the View menu setting includes Class folders. Step 2:Navigate to the device that controls the area where you want to change the setpoint, click on the + sign to display the Class folders Step 3:Select the AnalogValue folder and click on the + sign to display the folder’s objects.Step 4:Navigate to the object that represents the office or room you are attempting to change. In this example it is SampleOfficeTemp. Double-click on the object to switch to a detailed table view.Step 5: From the detailed view table, double-click the present-value property to display the Property View/Set dialog. (In this example, this value has a BACnet priority level setting
Chapter 5: Using the BACnet Service Tool Software80 TACof 8 (ManualOperator), which means you should have a level setting of 8 or higher to perform this change.)Step 6: Type the new setting into the value display area and click on the Apply button to make the change.Step 7: A success message should appear in the dialog and the table should be updated with the new value. Close the dialog to complete this task.In this example, we only changed the setpoint of the current temperature. We could have changed the high-limit and low-limit values to adjust the temperature range of operation or we could have changed other objects that would have adusted how the controller functions.
Chapter 5: Using the BACnet Service Tool SoftwareBACnet Service Tool User’s Guide 81Viewing a Trend Log BufferAnother common task is to view the history of events in a trend log buffer. If a system administrator has defined an AnalogValue to capture changes in a unit of value, such as ohms, relative humidy, watts, etc., these events can be logged and listed as an object in a Class folder (TrendLog is the folder name in this example).To view a trend log buffer, perform the following steps:Step 1: From the Service Tool graphical interface, make sure the View menu setting includes Class folders. Step 2: Navigate to the device where the trend logging is taking place, click on the + sign to display the Class folders. Step 3: Select the TrendLog folder and click on the + sign to display the folder’s objects.Step 4: Navigate to the object that represents the trend logging event you are looking for. In this example it is TestLog1. Double-click on the object to switch to a detailed table view.
Chapter 5: Using the BACnet Service Tool Software82 TACStep 5: From the detailed view table, double-click the log-buffer property to display the Property View/Set dialog .Step 6: View the contents. This dialog gives you three options. zYou can Clear the buffer and erase the contents zYou can Close the dialogzYou can Refresh the buffer and possibly display additional data that may have been captured while this dialog was open.Step 7: Close the dialog to complete this task.
Chapter 5: Using the BACnet Service Tool SoftwareBACnet Service Tool User’s Guide 83Viewing a Schedule of EventsViewing the particular details of schedule of events is another common task that you can perform using the Service Tool. An example of a schedule of events would include automatically changing high and low temperature setpoints at different times of the day, with some exceptions for weekends and holidays. From the Service Tool, you can view the following:zThe overall time period of the schedule of an eventzThe specific weekly schedule of event occuranceszThe time exceptions for an eventzThe list of object property references that trigger, or are affected by, an eventTo view the schedule details of an event, perform the following steps:
Chapter 5: Using the BACnet Service Tool Software84 TACStep 1: From the Service Tool graphical interface, make sure the View menu setting includes Class folders. Step 2: Navigate to the device where the schedule object has been defined and click on the + sign to display the Class folders. Step 3: Select the Schedule folder and click on the + sign to display the folder’s objects.Step 4: Navigate to the object that represents the event you are looking for. In this example it is SchTestOne. Double-click on the object to switch to a detailed table view.Step 5: From the detailed table, you can view the Property View/Set dialog on one or more of the following by double-clicking on the property.zeffective-period defines the duration of a scheduled eventzweekly-schedule defines the specific dates and times that an event is triggeredzexception-schedule defines the date and time exceptions to a schedulezlist-of-objects-property-references defines what defined objects and values are associated with an event.

Appendix A: What Is BACnet?86 TACIntroductionBACnet® stands for Building Automation and Control Network. It is a communication protocol developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc. (ASHRAE).BACnet integrates products made by different manufacturers into a single-building automated control system. This means that, as long as they meet ANSI/ASHRAE Standard 135-2004, products from different manufacturers can communicate with each other over a network. These different products include controllers, workstations, actuators, and sensors. In the BACnet world, each of these products is known as a device. BACnet is a common network technology that facilitiates communication among many different networked systems. Note: If you do not already have the ANSI/ASHRAE Standard 1350-2004 BACnet — A Data Communication Protocol for Building Automation and Control Networks, you can get it from the web site, http://www.bacnet.org/.BACnet support is integrated into Andover Continuum products, such as the BACnet service tool and Continuum CyberStation, in a way that ensures transparency and “sameness” in the user experience. Viewing and configuring networks, controllers, classes, objects, and properties in BACnet are similar. These BACnet elements are integrated into the “look and feel” of Andover Continuum products — for exmaple, application viewers, explorer trees, list views, object/point editors, graphics editors. Our proprietary Plain English (PE) programming language is used to program Andover Continuum BACnet devices. Some BACnet functions and features have been added to PE, allowing you to query and change points on other BACnet third-party devices. Through programming and the user interfaces of Andover Continuum products, Continuum’s implementation of BACnet allows you to manipulate Continuum/Infinity points that subsequently operates a BACnet device and vice versa.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 87For more information on integration, please see the section, BACnet and Andover Continuum, later in this appendix.Note: Andover Continuum’s integration of BACnet is fully documented in the Continuum online help, the Andover Continuum CyberStation Configurator’s Guide, 30-3001-781, the Introducing BACnet for the Continuum User Guide, 30-3001-863, and the Plain English Language Reference, 30-3001-872.
Appendix A: What Is BACnet?88 TACBACnet - Knowing the TerminologyThis section provides brief descriptions of the following fundamental BACnet components and terms:NetworkInternetworkDeviceProfileObjectPropertyServiceBroadcastPICSBIBBsCommand PriorityFor routers and BACnet Broadcast Management Devices (BBMDs), see the section, Routers, Gateways, BBMDs, and Foreign Devices, later in this appendix.What Is a BACnet Network?A BACnet network is a transport (LAN or WAN) that carries data from device to device, within a network and between networks. A BACnet network can be a high-speed backbone network:zEthernetzBACnet/IPAnd it can be a fieldbus network:zMaster-Slave/Token-Passing (MS/TP)zARCnetzLonTalk
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 89Note: Since many BACnet devices are located across the network on smaller subnetworks, the term Internetwork is often used in BACnet literature to describe an entire network of BACnet devices.What Are BACnet Devices?A BACnet device conforms to the BACnet standard and can serve as a:zBuilding controllerzField controllerzRouterzGatewayzEnd device, such as a sensor or actuator. Devices are networked together in a building as peer-to-peer devices, slave devices, or master/slave devices. How Are Devices Identified?Every device can be identified by:zA device identifier, which is an instance number that is unique to that device across many different networks that comprise a BACnet system. (See also What Is an Internetwork?.). A device instance number can be 1 to 4194303.zA network number that is unique to the network to which the device belongs. A network can be numbered 1 to 65535.
Appendix A: What Is BACnet?90 TACzA MAC address number that is unique only within its own network. The following table lists ranges of MAC address numbers for some BACnet networks:Note: A MAC address is typically read from a DIP switch or from non-volatile memory. Some devices auto-assign MAC addresses when the devices are placed on the network.BACnet devices can have input/output functionality or no input/output functionality.What Are Device Profiles?The BACnet standard identifies six device types, also known as device profiles. These are:zBACnet Operator Workstation (B-OWS)zBACnet Building Controller (B-BC)zBACnet Advanced Application Controller (B-AAC) zBACnet Application Specific Controller (B-ASC) zBACnet Smart Actuator (B-SA)zBACnet Smart Sensor (B-SS)For a list of Andover Continuum BACnet devices, please see the section, BACnet and Andover Continuum, later in this appendix.MAC Address NumbersNetwork Number RangeMS/TP 1 to 254ARCNET 1 to 255Ethernet 1 to 281474976710655
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 91What Are BACnet Objects?BACnet objects are the logical representation of system data. Objects represent data that originates in physical inputs, physical outputs, or software processes — for example, single physical points or logical groupings/collections of points, which perform a specific function. Objects standardize the organization of data to facilitate the exchange of data between the products of different manufacturers. Each object possesses a number of properties. The BACnet standard provides the following standard objects:AccumulatorAnalog_Input Analog_OutputAnalog_ValueAveragingBinary_InputBinary_OutputBinary_ValueCalendarCommandDeviceEvent_EnrollmentFileGroupLife_Safety_PointLife_Safety_ZoneLoopMulti_State_InputMulti_State_OutputMulti_State_ValueNotification_Class (supported as an EventNotification object)ProgramPulse ConverterScheduleTrend LogIndividual manufacturers may implement their own proprietary object types, as long as they conform to the BACnet standard.
Appendix A: What Is BACnet?92 TACFor a list of BACnet objects supported in Andover Continuum products, please see the section, BACnet and Andover Continuum, later in this appendix.How Are Objects Identified?Each object has a numerical object identifier comprising an object type and an instance number, as follows:zObject types 0 to 127 are reserved to identify standard BACnet objects.zObject types 128 to 1023 are used to identify proprietary objects.zBACnet devices support object types up to a limit of 4194303 instances. (As you know from the device section, instance numbers can be 1 to 4194303.)What Are BACnet Properties?Objects are examined and controlled by a set of properties that belong to each object. A property contains the smallest piece of BACnet information, and it has a name and a value. For example, a property named high_limit can hold a value of 78.0. A property can be written and/or read, and can provide command control.For every object, the BACnet standard requires some properties, while others are optional. Still other properties can be proprietary to a manufacturer. Required properties must be implemented for each object type. Optional properties need not be implemented, but if they are, they must conform to the BACnet standard.Each BACnet Device object contains properties that can be used to verify communications, identify the vendor, identify software and firmware revision, and other characteristics of the device. The device object’s properties represent the externally visible characteristics of a BACnet device.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 93How Are Properties Identified?Each property has a property identifier, which is a number. Properties 0 to 511 are reserved as standard, though only 166 properties are currently defined in the BACnet standard. Properties 512 and higher are unique to a manufacturer’s proprietary properties. For example, TAC (Andover Continuum) has three proprietary properties:512 — PreviousTransitionTime513 — NextTransitionTime514 — FollowingTransitionTimeThe Device object property, Vendor ID, is used to identify the manufacturer. What Are Complex Properties?Information not available for Beta.What Are BACnet Services?BACnet services are essentially the messages that BACnet devices send to each other. Services can:zRead and write the property values of one or more objects.zSend notifications of alarms and special events.zRead and write files.Services follow a basic client/server model. A BACnet client is a device that requests a service. A BACnet server is a device that performs a service. (See also What Are BACnet Broadcasts?)
Appendix A: What Is BACnet?94 TACThe following table lists the major categories of BACnet services:What Are BIBBs?BACnet Interoperability Building Blocks (BIBBs) are collections of BACnet services. They represent the next detailed layer of service components. BIBBs are grouped into the following five five major categories:zData SharingzAlarm and Event ManagementzSchedulingzTrendingzDevice and Network ManagementDifferent combinations of BIBBs apply to each type (profile) of BACnet device — B-OWS, B-BC, B-AAC, B-ASC, B-SA, B-SS. For example, the following table summarizes the BIBB services provided for a B-BC type of device.BACnet Service CategoriesCategory ServiceAlarm and Event Performs alarm routing and event notificationFile Access Accesses and manipulates files contained in devices.Object Access Reads and writes properties, creates and deletes objects, and manipulates lists of dataRemote Device ManagementRemotely monitors and controls devices.Virtual Terminal Esablishes, for a client user, a connection to an application program server in another BACnet device.Example: BIBBs for a B-BC Type DeviceBIBB Category Capabilities & Services Provided for a B-BCData Sharing zProvides values of any of its BACnet objectszRetrieves values of BACnet objects from other devices.zModifies some/all of its BACnet objects by another devicezModifies some BACnet objects in other devices.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 95See also: What Are BACnet Services?What Are BACnet Broadcasts?A BACnet broadcast is a User Datagram Protocol (UDP) broadcast that carries messages (or services) from one device to another. These broadcasts, for example, can be:zA query from a device that seeks to discover the existence of other devices and their objects. In the BACnet world, this is known as a Who-Is broadcast.zAn announcement from a device that informs other devices of its existence, identifying itself and its objects. In the BACnet world, this is known as an I-Am broadcast.zBroadcasts that deliver alarm messages to devices.Alarm and Event ManagementzGenerates alarm/event notifications and directs them to recipients.zMaintains a list of unacknowledged alarms/events.zNotifies other recipients that the acknolwedgement has been recieved.zAdjusts alarm/event parameters.Scheduling zSchedules output actions, both in the local device, and in other devices, both binary and analog, based on the date and time.Trending zCollects and delivers time/value pairs.Device and Network ManagementzResponds to queries about its status.zResponds to requests for information about any of its objects.zResponds to communication control messages.zSynchronizes its internal clock upon request.zUploads its configuration and allows it to be subsequently restored.zCommands half-routers to establish and terminate connections.Example: BIBBs for a B-BC Type DeviceBIBB Category Capabilities & Services Provided for a B-BC
Appendix A: What Is BACnet?96 TACzBroadcasts that inform other devices that the value of one or more objects/points has changed. In the BACnet world, these are known as Change Of Value (COV) messages.Broadcasts are sent and received through a UDP port on each device. Each device on a network has a unique UDP port number. The default port number is [0xBAC0]. They are also sent using an IP router and a BACnet Broadcast Managment Device (BBMD).For more information on routers and BBMDs, please see the section, Routers, Gateways, BBMDs, and Foreign Devices, later in this appendix. See also: What Are BACnet Services?What Is BACnet Command Priority?In an Andover Continuum building control system, an object may be manipulated by a number of different entities. The current value of an object is set by several applications and other sources.Each application has a well-defined function that it needs to perform. When the actions of two or more applications conflict, with regard to the value of an object property, there is a need to arbitrate between them. Arbitration ensures that several program and non-program sources can properly manipulate the value of the same object. For example, a start/stop program may command a particular BinaryOutput to turn ON, while a demand-metering program may command the same BinaryOutput to turn OFF. In this case, the OFF takes precedence. However, an operator might override the demand-metering program and force the BinaryOutput ON, in which case the ON takes precedence.The Command Priority ProcessIn BACnet, arbitration is provided by a process known as command priority, which assigns varying levels of priorities to commanding entities throughout the system. Each object that contains a "commandable" property is responsible for acting on prioritized commands, in the order of their established priorities.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 97Implementation of the command priority process in an Andover Continuum system involves the following command priority properties:zCommandable Property — Each object that supports command priorities has one or more properties that are known as commandable properties. The value of these properties is controlled by the command priority process.zPriority_Array — BACnet has established a set of 16 priority levels, known as the priority array, which consists of commands or NULLs, in an order of decreasing priority. The highest priority (lowest array priority level) with a non-NULL value is the active command. If a priority level holds a value of NULL, then the next non-NULL is assigned to the object.zRelinquish_Default — When all priority levels in the priority array become NULL, the value of Relinquish Default is assigned to the commandable property. You set the value of Relinquish Default when you configure the BACnet object..Command Values and NULLs A priority level in the priority array may have a commanded value or a NULL value. A NULL value means there is no existing command at that priority. An object continuously monitors (polls) the entire priority array to locate the entry with the highest non-NULL value, then sets the commandable property to this value.Relinquishing a Command A commanding entity (application program or operator, for example) may issue a command to an object's commandable property, or it may relinquish a command issued earlier. Relinquishing is a write operation, similar to the command itself, except that the value of NULL is commanded. That is, relinquishing a command places a NULL value in the priority array, corresponding to the appropriate priority. (You may override and relinquish a commanded value.)
Appendix A: What Is BACnet?98 TACThe 16-Element BACnet Command Priority ArrayIn the 16-level BACnet priority array, the top two priorities are related to personnel safety. Five of the 16 priority levels have been assigned a priority. However, the remaining 11 levels are designated as "available" for possible future use. These priorities are:1 — Manual Life Safety2 — Automatic Life Safety3 — Priority 3, available4 — Priority 4, available5 — Critical Equipment Control6 — Minimum On Off7 — Priority 7, available8 — Manual Operator9 — Priority 9, available10 — Priority 10, available11 — Priority 11, available12 — Priority 12, available13 — Priority 13, available14 — Priority 14, available15 — Priority 15, available16 — Priority 16, availableNote: If an attempt is made to command a property for which a priority level has not been specified, a default priority level of 16 (the lowest priority) is assumed. If an attempt is made to command a property that is not commandable with a specified priority level, the priority shall be ignored. For more information on Andover Continuum’s implementation of BACnet comand priority, please see the Continuum online help and the Andover Continuum CyberStation Configurator’s Guide, 30-3001-781.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 99What Are BACnet PICS?BACnet Protocol Implementation Conformance Statements (PICS) are detailed descriptions of a device’s inherent BACnet capabilities. PICS can:zTell a potential user what objects and BACnet services a device supports. zDetail the type of communications network, the baud rate, the range of values each object property expects.zSpecify whether a property is either writeable or just read-only. zAssess the level of interoperability between devices.PICS are available from each BACnet manufacturer.
Appendix A: What Is BACnet?100 TACBACnet and Andover ContinuumAs you learned in the Introduction section earlier in this appendix, BACnet support is integrated into Andover Continuum products — both software and hardware — in a way that ensures transparency and “sameness” in the user experience. Creating, viewing, finding, and configuring BACnet networks, controllers, classes, objects, and properties is very similar to the ways you would do these things without BACnet. The BACnet elements are integrated into the “look and feel” of Andover Continuum products — for example, application viewers, explorer trees, list views, object/point editors, graphics editors, and the proprietary Plain English programming language.Note: Andover Continuum’s integration of BACnet is fully documented in the Continuum online help, the Andover Continuum CyberStation Configurator’s Guide, 30-3001-781, the Introducing BACnet for the Continuum User Guide, 30-3001-863, and the Plain English Language Reference, 30-3001-872.Andover Continuum vs. BACnet Terminology — a RoadmapWhen working with Andover Continuum’s implementation of BACnet, the following tips may help you “map” Continuum/Infinity terminology to BACnet terminology:zAn attribute in the Continuum/Infinity world is a property in the BACnet world.zA point in the Continuum/Infinity world is an object in the BACnet world.zA controller in the Continuum/Infinity world is a device in the BACnet world.zAn alarm in the Continuum/Infinity world is an event in the BACnet world.zThe term digital in the Continuum/Infinity world generally means binary in the BACnet world.zThe term class (as in class object) means the same in both worlds.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 101Andover Continuum BACnet DevicesAndover Continuum BACnet devices are “native” BACnet, meaning that they can interoperate directly with other manufacturers’ (third-party) BACnet devices. They inherently represent internal data in BACnet format and use BACnet messaging to communicate. Andover Continuum BACnet devices can be connected to a BACnet system without requiring a gateway device or software driver to translate to and from proprietary protocols. The following table lists Andover Continuum BACnet devices and matches them with their respective BACnet device profile.How BACnet Devices Are Created in Andover ContinuumAn Andover Continuum BACnet device (BACnet class object Device) is first created as a Continuum InfinityController object or an InfinityInfinetCtlr object. For example, when an InfinityController object is created, and it is designated as a b4920 or bCX1 4040, it automatically becomes a Device object when it appears in the BACnet section of Continuum’s tree-view structure, known as the Continuum Explorer. In fact, in Continuum Explorer you can see the InfinityController object residing in the Infinity view and its Device object equivalent residing in the BACnet view.Third-party BACnet devices are absorbed into a Continuum system and appear as Device objects only in the BACnet view.

Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 103How BACnet Objects Are Created in Andover ContinuumYou may create and/or modify BACnet objects in an Andover Continuum system. Most of these objects are first created as Continuum/Infinity objects, and depending how they are configured, they are automatically transformed into BACnet objects when they are created on an Andover Continuum BACnet controller, such as a bCX1 4040.For example, when a Continuum InfinityInput object is created on an Andover Continuum BACnet controller, and the input type is “voltage,” it automatically becomes an AnalogInput object when it appears inthe BACnet section of Continuum’s tree-view structure, the Continuum Explorer.Most BACnet objects are created as Continuum/Infinity objects on an Andover Continuum BACnet controller, as follows:AnalogInput (created as an InfinityInput)AnalogOutput (created as an InfinityOutput)AnalogValue (created as an InfinityNumeric)BinaryInput (created as an InfinityInput)BinaryOutput (created as an InfinityOutput)BinaryValue (created as an InfinityNumeric)Device (created as an InfinityController or InfinityInfinetController)EventEnrollment (created as an AlarmEnrollment)MultistateInput (created as an InfinityInput)MultistateOutput (created as an InfinityOutput)MultistateValue (created as an InfinityNumeric)Notification_Class (created as an EventNotification)Third-party BACnet objects are absorbed into a Continuum system and appear only in the BACnet view.Pulse Converter No N/ASchedule Yes ScheduleTrend Log Yes TrendLogBACnet Objects Suported in Andover ContinuumBACnet Object Name Supported?

A class object folder, typically created for each device, contains all the objects residing on that device for that class. For example, a class folder named InfinityNumeric would contain InfinityNumeric objects residing with its respective Infinity controller. On the BACnet side, the equivalent class folder, named AnalogValue, would reside with its respective BACnet device. For example, the Infinity view might have an InfinityInfinetCtlr class folder, while on the BACnet view the folder would be named Device.BACnet Properties and Andover ContinuumAs you recall from earlier in this appendix, every BACnet object has many BACnet standard properties (and sometimes proprietary properties). The BACnet standard defines the names of standard properties. Andover Continuum implements these properties (or subsets of these properties) in its object editors and its Plain English (PE) programming language, compliant with the BACnet standard. However, property names used in Andover Continuum and in Plain English differ slightly, just as Continuum object names differ slightly. This maintains the same funcitonal “look and feel” in the integration of BACnet into Andover Continuum products.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 105The following table shows some examples of how the BACnet standard property names may differ from the way they appear to Continuum internally and in Plain English programs, as well as they way they appear in the Continuum user interface (object editors).For more information please see Introducing BACnet - A Guide for the Continuum User, 30-3001-863, and the Plain English Language Reference, 30-3001-872.Variations of Property Names in Andover ContinuumBACnet Standard Property NameInternal Continuum and PE Program NameContinuum User Interface NameEvent_State EventState Event StateObject_Name ObjectName NameOut_Of_Service OutOfService Out of ServicePresent_Value Value Present ValueDescription Description Description
Appendix A: What Is BACnet?106 TACRouters, Gateways, BBMDs, and Foreign DevicesThis section describes some other types of BACnet devices:zRouterszGatewayszBACnet Broadcast Management Devices (BBMDs)zForeign devicesRouters and GatewaysA router (or IP router) is a BACnet device, such as the Andover Continuum bCX1 4000, that facilitates the exchange of data between different types of BACnet networks — MS/TP, BACnet/IP, Ethernet, and so on. A router is simply a “pass through” device. It does not change the data format or the content of the message. This exchange of broadcast messages between networks, using a router, requires a BACnet Broadcast Management Device (BBMD) — one BBMD per network. (For more information on BBMDs, please see the section, BBMDs and Foreign Devices, below.)A gateway is a BACnet device that facilitates exchange of data between devices on a BACnet network and devices on a non-BACnet network so that BACnet and non-BACnet information can be shared. While a router simply passes information from one network to another, a gateway takes the data from one device, analyzes it, translates the data into another data protocol (BACnet or non-BACnet), then delivers it. This ensures the recipient device understands the message.Physically, a gateway can take one of the following forms:zInternal: This is typically a board or module inside a device.zExternal hardware/software: This is typically an external hardware interface box combined with a software translator.zSoftware: This is typically a software translator on a PC.Note: These exchanges of data, via routers and gateways, are also known as internetworking.
Appendix A: What Is BACnet?BACnet Service Tool User’s Guide 107BBMDs and Foreign DevicesA BBMD is a workstation (B-OWS) specially designated to ensure that broadcast messages are delivered, via one or more routers, between BACnet networks. (See also the sections: Routers and Gateways, and What Are BACnet Broadcasts?) Each network must have a BBMD. Each BBMD maintains two internal tables:zBroadcast Distribution Table (BDT)zForeign Device Table (FDT)These tables essentially allow different networks to know about the existence of each other and each other’s devices. They must know about each other before broadcast messages can be routed. A BDT maintains a list of other BBMDs located on other “foreign” networks. If a “foreign” BBMD is added to a BDT, then it becomes registered in the “local” BBMD. During this process, not only does that “foreign” BBMD get registered, but all the BBMDs listed in its “foreign” BDT also get registered. This means the local network knows about the foreign network and all the networks that the foreign network knows about.An FDT maintains a list of foreign devices. A foreign device is simply the identity of a device residing on another BACnet network. When a foreign device is added to an FDT, then it also becomes registered with the “local” BBMD. Note: In Andover Continuum CyberStation, you can designate and register BBMDs, as well as register foreign devices, so that broadcast messages are routed among BACnet networks. For more information, please see the Continuum online help, the Continuum CyberStation Configurator’s Guide, 30-3001-781, and Introducing BACnet - A Guide for the Continuum User, 30-3001-863.
