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).

Click the attribute name in the table for a description of the attribute.

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 Object’s Reliability, W - Writable.

Description

Connected To Internal Application

 

B,W

No

No or Yes

Indicates whether the object is connected to an internal application.

Current Command Priority

 

B

 

1 - 16

Indicates the command priority currently assigned to the object. A blank in this field indicates the object is not under any command.

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.

Intrinsic Alarming Defined

C

Not supported

False

False

True

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.

Number of States

C,W

W

4

2 to 32

This attribute is not writable through the MS/TP integration. You must configure this attribute through CCT.

Out of Service

   

False

Always False

Present Value

D,R,W

D,R,W

 

States Text attribute identifies the value set for this attribute.

Note: If Present Value is commandable, then it must be writable. If Out of Service is True, this attribute is True.

Priority Array

      If Present Value is commandable, this attribute is present.

Property Ref Value

N

   

Object Name, Reference, Attribute

Specifies an object and attribute (usually from an application) for which the MV 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. 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), Multistate Fault, Unreliable Other

Uses Reliability (Set 503).

Indicates whether the Present Value is reliable and why. If Fault Values is present, Reliability is also present. A To Fault event generates under these conditions: Reliability is not equal to No Fault Detected, and the To Fault flag is enabled in Event Enable.

The Reliability attribute is always present in NAE implementations.

State Text

       

States Text

C,W

C,W

   

States Text Error Status

   

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.

This attribute shows the status of States Text on the supervisory device. This attribute is not archivable or configurable.

Status Flags

     

In Alarm, Fault, Overridden, Out of Service

Uses BAC Status Flags (Set 9).

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 the operator 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.
