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: C - Configurable, D - Default Attribute for Display, N - Value Not Required, R - Affected by Object’s Reliability, W - Writable.

Table 1. Multistate Value Object Attributes - Focus/Configuration Tab
Attribute Name	Notes	BACnet Notes	Initial Value	Values/Options/Range	Description
Connected To Internal Application		B,W	No	No or Yes	Indicates whether the object is connected to an internal application.
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	Enables the BACnet Intrinsic Alarming feature in the object and the definition of related attributes.
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	Defines the number of states possible for Present Value. This attribute is not writable through the MS/TP integration. You must configure this attribute through CCT.
Out of Service			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 object does not read the hardware. This attribute is always False.
Present Value	D,R,W	D,R,W		States Text attribute identifies the value set for this attribute.	Reflects the current value of the multistate value object as one of n states, where n is the number of states defined in the Number of States attribute. The Present Value is equal to the last value corresponding to the States Text attribute. Present Value is optionally commandable. If Present Value is commandable for a given object instance, then Priority Array and Relinquish Default are also present for that instance. If Out of Service is true, Present Value is writable. 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.	Contains prioritized commands that are in effect for this object. See the BACnet standard for a description of the prioritization mechanism. If either Priority Array or Relinquish Default is present, both are present. If Present Value is commandable, Priority Array and Relinquish Default are both 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					Represents descriptions of all possible states of Present Value. The number of descriptions matches the number of states defined in Number of States. Present Value (an integer) serves as an index into this attribute.
States Text	C,W	C,W			Indicates the displayed strings for the Present Value.
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).	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 get 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 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.
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.
