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.

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.

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

Min On Time

C,W

W

0

0–4,294,967,295

Units = seconds

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

Present Value

D,R,W

D,R,W

 

Inactive, Active States Text attribute identifies the value set for this attribute.

Present Value is commandable; it is also writable. This attribute is writable when Out of Service is True.

Priority Array

       

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

State Count Reset

W

B, W

   

If Change of State Time, Change of State Count, or State Count Reset is present, all are present.

States Text

C,W

 

Inactive, Active

 

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

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.
