Table 1 describes the Binary Output object attributes. These attributes are displayed in alphabetical order. See Object Attributes in the Input and Output Objects section for descriptions of the data provided in this table. Unless otherwise stated, the attributes listed in this table appear in the Details dialog box (for example, the Present Value appears in the Control View below the module name in Simulation and Commissioning modes).

Table 1. Binary Output Attributes
Name	Type	Mode	Description
Active Text	Property	Configuration Commissioning	Indicates the active state of the object (for example, Occupied, Cooling, or Active).
Device Type	Property	Configuration Commissioning	Describes the physical network device to which the object is connected.
Description	Property	All Modes	Indicates the description provided for the object.
Heavy Equip Delay	Property	Configuration Commissioning	Represents the minimum amount of time between the activation of the current load and the activation of the next load. When a HED controller is designated, it uses this value to assure the separation between activations. The HED holds Present Value as Inactive by writing to it at Heavy Equip Delay priority (7). The attribute applies only when Present Value is written at priorities lower than the Heavy Equip Delay priority (7). Range: 0 - 255
HED Controller	Property	Configuration Commissioning	Contains the object reference for the Heavy Equipment Controller that services HED function calls for this object. Range: 1 - 5
Ignore Relinquish Default	Property	Configuration	Indicates whether the Relinquish Default is used. When True, the Relinquish Default attribute is not used and has no effect.
Inactive Text	Property	Configuration Commissioning	Indicates the inactive state of the object (for example, Not Occupied, Heating, or Inactive).
Min Change to Send	Property	All Modes	Indicates the array of floating values (each value corresponding to a single Input) to specify the minimum change in the Input that is sent to the destination. This attribute is only applicable when the Input is of floating-point data type. The change is evaluated by comparing the current value of the Input to the value the last time a message was sent to the destination.
Min Cycle Time	Property	Configuration Commissioning	Represents the minimum total amount of time for the following transitions: transition from Inactive (or Hold) to Active transition from Active to Inactive transition from Inactive to Active If the object stays in an Active state for less than the Min On Time, the object is held Inactive at the Minimum Off priority for the remainder of the Minimum Cycle Time (or Min Off Time, whichever is longer) so that the minimum cycle time is maintained. Note: For modules that are driven by the MSC, Minimum Cycle Time, Min On Time, and Min Off Time should be configured at the Output Controller module and must be set to 0 in the Binary Output. Range: 0 - 65,535
Min Off Time	Property	Configuration Commissioning	Represents the minimum amount of time the hardware output must remain Inactive between deactivation and activation. The hardware output is Inactive at the Minimum On Off priority for the time specified in this attribute. Note: For modules that are driven by the MSC, Minimum Cycle Time, Min On Time, and Min Off Time should be configured at the Output Controller module and must be set to 0 in the Binary Output. Range: 0 - 604,800
Min On Time	Property	Configuration Commissioning	Represents the minimum amount of time the object must remain Active between activation and deactivation. The object is Active at the Minimum On Off priority for the time specified in this attribute. Note: For modules that are driven by the MSC, Minimum Cycle Time, Min On Time, and Min Off Time should be configured at the Output Controller module and must be set to 0 in the Binary Output. Range: 0 - 604,800
Name	Property	All Modes	Indicates the name of the object.
Object Identifier	Property	Configuration Commissioning	Indicates the instance number of the Object Type as exposed to the network. The Object Identifier must be unique within the host device. The Object Identifier is created after defining hardware in the Hardware Definition Wizard accessible from the Define Hardware button. The Object Identifier consists of the BACnet Class ID and the object’s Instance Number separated by a colon. For example, an Object Identifier of AV:10026 has a BACnet Class ID of AV and an Instance Number of 10026.
Offline	Property	Commissioning	Indicates if the object is currently communicating with the network device. This attribute is visible in an SAB device.
Out of Service	Property	Commissioning	Indicates whether the object is currently connected to the hardware or offline (out of service). This attribute is visible in an SAB device.
Priority	Input	All Modes	Sends the output at the BACnet priority indicated by the value of the priority input.
Polarity	Property	Configuration Commissioning	Indicates the following, depending on the mode: Normal Reverse If the Object is Out of Service, this attribute has no effect on Present Value. Set Name: Polarity
Present Value (Appears as I1)	Input	Simulation Commissioning	Indicates the current value (with the highest priority) being sent to this object. Only values of Inactive or Active can be written to this attribute. Note: A value of Hold means that the hardware output has not been commanded to Inactive or Active since the last device cold start, and the true status of the hardware output is unknown. Hold is used by Pulse and Start Stop devices. Hardware outputs do not change while Present Value is Hold. Set Name: See States Text. This attribute is an input to a binary output.
Pulse Width	Property	Configuration Commissioning	Specifies how many seconds each pulse should remain Active following activation. Note: In Maintained mode, this attribute is not used. Note: A write to this attribute does not affect a pulse currently in progress. Instead, the change takes effect for the next pulse. Note: If the BO goes out of service during a pulse, the pulse completes normally. Range: 0 - 100
Reliability	Property	Simulation Commissioning	Provides the following values to indicate whether or not the Present Value is reliable: Connection Fail: The object fails to connect to the hardware. Reliable: The object is not in Connection Fail. If an Out of Service command is received, this attribute is Reliable. Only when the object is out of service can you write values to this attribute. Set Name: Reliability This attribute is a calculated value (Output).
Relinquish Default	Property	Configuration Commissioning	Contains the default value for Present Value when all priorities are released. The Present Value is sent to the value in Relinquish Default only at startup or when the last priority value is released. Present Value does not update if you change Relinquish Default.
Restore Command Priority	Property	Configuration Commissioning	Restores the commands you select in the case of a power failure. For more information about command priorities, see Command Priority Levels. The following list displays the command priorities you can select. Operator Override Default
Startup OFF State Enable	Property	Configuration Commissioning	When enabled, prevents the field device from commanding its outputs on until a command is received from the supervisory device.
States Text	Property	Configuration Commissioning	Indicates the set number used by Present Value. Set Name: Two State
Status	Property	Simulation Commissioning	Reflects the status of the object based on the Reliability attribute and the status of any commands. Possible values for Binary Output objects are: Out of Service: Out of Service is True. High Priority: Present Value is currently controlled at Priority 1 - 5. Min On Min Off: Present Value is currently controlled at Priority 6. Heavy Equip Delay: Present Value is currently controlled at Priority 7. Operator Override: Present Value is currently controlled at Priority 8. Unreliable: Reliability is not reliable. Normal: None of the above is correct. Note: Priorities for Min On Min Off (6) and Operator Override (8) are specified by BACnet requirements. The priority for Heavy Equip Delay (7) follows Johnson Controls conventions. Set Name: Status This attribute is a calculated value (Output).
Use Default if Not Reliable	Property	All Modes	Specifies the behavior when the Input is not reliable. If True, the destination is sent the Input’s Default Value whenever the Input is not reliable and its Reliability is marked as Reliable. If False, the destination is not updated and keeps its last reliable value.
