This object contains attributes common to many Metasys system objects. This section includes attributes of the Focus/Configuration tab. See the Object and Feature Tabs section for information on the attributes that appear on the other tabs of this object (for example, the Hardware and Options tab appear on point objects).

Note: In the Notes and BACnet Notes columns, letters indicate the following: B - Exposed as standard BACnet property, C - Configurable, D - Default Attribute for Display, N - Value Not Required, R - Affected by Extension’s Reliability, W - Writable.

Table 1. Binary Value Object Attributes - Focus/Configuration Tab
Attribute Name	Notes	BACnet Notes	Initial Value	Values/Options/Range	Description
Active Text				Limit: 20 characters	Characterizes the intended effect of the Active state of Present Value from the viewpoint of the operator. The content of this string is a local matter but is intended to represent a readable description of the Active state. If either the Active Text or the Inactive Text attribute is present, both of them are present. If either Inactive Text or Active Text is present, both are present.
Active Time Reset	W	B, W			Represents the last date and time Elapsed Active Time set to a zero value. If either Elapsed Active Time or Time of Active Time Reset is present, both are present.
Connected To Internal Application		B, W	No	No or Yes	Indicates whether the object is connected to an internal application.
COS Count	W		0	0–4,294,967,295	This attribute is persisted in the archive. Represents the number of times the Present Value attribute changed state since the COS Count attribute was last set to zero. A change of state is any event that alters Present Value. This attribute persists in the archive. If Change of State Time, Change of State Count, or State Count Reset is present, all are present.
COS Time			Null		Represents the date and time at which the most recent change of state occurred. A change of state is any event that alters the logical state of Binary Value. If Change of State Time, Change of State Count, or State Count Reset is present, all are present.
Elapsed Active Time			Null	0–4,294,967,295 Units = seconds	Represents the accumulated number of seconds Present Value is Active since the Elapsed Active Time attribute was last set to zero. This attribute value updates automatically a minimum of once a day. If either Elapsed Active Time or Active Time Reset is present, both are present.
Failsoft Currently Active				Yes or No	Specifies whether the Failsoft feature is currently overriding the input value to a reliable default. If No, Failsoft is disabled or, if Failsoft is enabled, the value is reliable. If Yes, Failsoft is enabled and the value is unreliable. This attribute is only used if Property Ref Value is defined to reference an application.
Inactive Time				Limit: 20 characters	Characterizes the intended effect of the Inactive state of Present Value attribute from the viewpoint of the operator. The content of this string is a local matter, but it is intended to represent a readable description of the Inactive state. If either the Inactive Text or Active Text attribute is present, both are present. If either Inactive Text or Active Text is present, both are present.
Intrinsic Alarming	C	Not supported	False	False True	Enables (True) or disables (False) BACnet intrinsic alarming for this object. When disabled, writing to any of the intrinsic alarming attributes returns a Write_Access_Denied error. When disabled, reading the intrinsic alarming attributes returns the default value of each attribute. For detailed information, see BACnet Intrinsic Alarming.
Min Off Time	C,W	W	0	0–4,294,967,295 Units = seconds	Represents the least number of seconds Present Value remains in the Inactive state after entering the Inactive state.
Min On Time	C,W	W	0	0–4,294,967,295 Units = seconds	Represents the least number of seconds Present Value remains in the Active state after entering the Active state.
Monitor Only				False	Defines the behavior of the object as an input or output. If you do not specify a Property Ref Value, the attribute is set to False. This attribute appears only in the Snapshot Focus view.
Out of Service		W	False	Always False	Indicates the offline/online state of the connected hardware. This attribute exists for compatibility with BACnet protocol and indicates whether the physical input that the object represents is in service. When out of service, the physical input is not coupled to changes in the Present Value. The object does not send commands to the hardware. This attribute is always False due to the absence of hardware.
Present Value	D,R,W	D,R,W		Inactive, Active States Text attribute identifies the value set for this attribute.	Indicates the current value of the binary value. When Out of Service is True, Present Value is writable. Present Value is optionally commandable. If Present Value is commandable, Priority Array and Relinquish Default are both present. Present Value is commandable; it is also writable. This attribute is writable when Out of Service is True.
Priority Array					Lists values of the object in level of importance. If Priority Array or Relinquish Default is present, both are present. If Present Value is commandable, Priority Array and Relinquish Default are both present and Present Value is writable.
Property Ref Value	N			Object Name, Reference, Attribute	Specifies an object and attribute (usually from an application) for which the BV object is providing the standard interface. The object and attribute contained in this attribute must be a local object and is often a non-BACnet data source and destination. When this property is not defined, the Monitor Only property is set to False. This attribute appears only in the Snapshot Focus view.
Referenced Reliability				No Input	Specifies the current reliability of the value sent to or from the object/attribute referenced by Property Ref Value. This attribute is only used if Property Ref Value is defined to reference an application.
Referenced Value					Specifies the current value sent to or from the object/attribute referenced by Property Ref Value. This attribute is only used if Property Ref Value is defined to reference an application.
Referenced Value COS Count	W		0		Counts how many times the Present Value and Reliability have changed. If the Monitor Only attribute is True, the count is how many times the Property Ref Value has updated the BV. If Monitor Only is False, the count is how many times Property Ref Value has updated the BV. This attribute helps to diagnose excessive changes that can cause logic to execute taking up too much bandwidth. Reset the count by entering 0 for this attribute. This attribute is only used if Property Ref Value is defined to reference an application.
Reliability	W	W	Reliable	No Fault Detected (Reliable), Unreliable Other, Communication Failure	Indicates whether the Present Value is unreliable and why.
State Count Reset	W	B, W			Represents the date and time the COS Count attribute was last set to a zero value. If COS Time, Change of State Count, or Time of State Count Reset is present, all are present. If Change of State Time, Change of State Count, or State Count Reset is present, all are present.
States Text	C,W		Inactive, Active		Indicates the displayed strings for the Present Value. For BACnet compliant objects, if no States Text is specified when the object is created, the Inactive Text and Active Text are used to derive the equivalent States Text if possible.
States Text Error Status			OK	Out of Memory, OK	Out of Memory: Indicates that memory overrun has been encountered while adding custom enumeration for state text from field device to the user dictionary. OK: Indicates that an addition of custom enumeration for state text from the field device to user dictionary is successful and state text from the device can be used.
Status Flag				In Alarm, Fault, Overridden, Out of Service	Contains four true or false flags that indicate the general health of the object. Three of the four flags are associated with the values of other attributes within the same object. By reading these attributes, you can achieve a clearer picture of the object status. The four flags are: In Alarm - In Alarm flag is False (0) if the Event State attribute value is Normal; otherwise, the In Alarm flag is True (1). Fault - Fault flag is True (1) if the Reliability attribute is not reliable; otherwise, the Fault flag is False (0). Overridden - Overridden flag is Logical 1 if the Present Value has been overridden by some mechanism local to the BACnet device or because operator intervention provided a different value. Out of Service - Out of Service flag is True if the Out of Service attribute value is True; otherwise, the Out of Service flag is False.
Use Remote Alarming		B,C,W	False		When the attribute Intrinsic Alarming Defined is set to True, determines where alarms for the object originate. If the remote integrated object contains attributes for originating alarms, then Use Remote Alarming defaults to True, causing the local mapper object to accept alarms from the remote integrated object that are routed to the NxE. If the remote integrated object does not contain attributes for originating alarms, then Use Remote Alarming defaults to False causing the local mapper object to originate alarms. When Use Remote Alarming is false, any alarms from the remote integrated object are ignored at the NxE. If the value of Use Remote Alarming is changed, a restart of the NxE may be required to assure correct operation. This attribute applies only to BACnet integrations.
