Table 1 describes the Binary Input 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 Input Attributes

Name

Type

Mode

Description

Active Text

Input

Configuration

Commissioning

Indicates the active state of the object (for example, Occupied, Cooling, or Active). This value for this attribute matches the active state name in States Text.

Application COV

Input

All Modes

Not used by this object.

Debounce

Input

Configuration

Commissioning

Indicates the length of time that the hardware input must remain in a state for the connected object to detect that a change has occurred. The hardware contact may bounce, producing extra input pulses. You can use the Debounce attribute to eliminate these nuisance input pulses. Contact fluctuations are ignored and, thus, filtered during this time period.

Device Type

Input

Configuration

Commissioning

Describes the physical network device to which the object is connected.

Description

Input

All Modes

Indicates the description provided for the object.

Inactive Text

Input

Configuration

Commissioning

Indicates the inactive state of the object (for example, Not Occupied, Heating, or Inactive). This value for this attribute matches the inactive state name in States Text.

Name

Input

All Modes

Indicates the name of the object.

Object Identifier

Input

All Modes

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 or Operations menu option.

The Object Identifier consists of the BACnetClass 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

Input

Commissioning

Indicates if the object is currently communicating with the network device.

This attribute is visible in an SAB device.

Out of Service

Input

Commissioning

Indicates whether the object is currently connected to the hardware or offline (out of service).This attribute is visible in an SAB device.

Polarity

Input

Configuration

Commissioning

Indicates the relationship between the physical state of the input read from the hardware and the logical state represented by Present Value (Appears as O1). If the Object is Out of Service, this attribute has no effect on Present Value.

Set Name: Polarity

Present Value (Appears as O1)

Input

Simulation

Commissioning

Reflects the current physical state of a device based on the state of the input and Polarity. This attribute changes when the following occurs:
  • If the Present Value attribute is changed by a user editing the attribute. This can be done only when Out of Service is False.
  • If changes occur in the hardware input (when the object has a live connection to the hardware).
  • If, on a transition from offline to a live connection to the hardware, the Present Value uses the last value reported from the hardware. If a value was never recorded before going offline, the value is not updated and Reliability goes to Connection Fail.

Set Name: States Text

This attribute is a Default Element, and is a calculated value (Output).

Priority

Input

All Modes

Contains the current BACnet priority of the referenced object if it supports BACnet priorities.

Reliability

Input

Simulation

Commissioning

Provides the following values to indicate whether or not the Present Value (Appears as O1) is reliable:
  • Connection Fail: The object fails to connect to the hardware.
  • Reliable: The object is not in the Connection Fail state.

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.

The controller must be online for this attribute value to appear.

Set Name: Reliability

This attribute is a calculated value (Output).

Source References

Input

Simulation

Commissioning

Indicates the array of attribute references for the sources. All references must be from a single object.

States Text

Input

Configuration

Commissioning

Indicates the set used by Present Value (Appears as O1).

Set Name: Two State

Status

Input

Simulation

Commissioning

Reflects the status of the object based on the Reliability attribute and the status of any commands.

Possible values for Binary Input objects are:
  • Out of Service: Out of Service is True.
  • Unreliable: Reliability is not reliable.
  • Normal: Neither of the above is correct.

The controller must be online for this attribute value to appear.

Set Name: Status

This attribute is a calculated value (Output).

Use Default if Not Reliable

Input

All Modes

Specifies the behavior when the Source is not reliable. If True, the Output is set to its Default Value whenever its Source is not reliable and its Reliability is marked as Reliable. If False, the Output maintains its last reliable value and its Reliability reflects the reason that the source is not reliable.
