This object contains attributes common to many Metasys system objects. This section includes attributes of the Focus/Configuration tab, the Diagnostics tab (if applicable), and any other tab specific only to this object. 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.

Attribute Name

Notes

BACnet Notes

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.

For example, if the physical output is a switch contact, then the Active Text attribute is assigned a value such as

Fan 1 On. If either the Active Text or the Inactive Text attribute is present, both of them 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 Active Time Reset is present, both are present.

COS Count

W

 

0–4,294,967,295

COS Time

     

Represents the date and time at which the most recent change of state occurred. A change of state is any event that alters the Present Value attribute. When Out of Service is False, a change to the Polarity attribute alters Present Value and is considered a change of state. Changes to Polarity do not cause changes of state.

Device Type

C,W

W

Limit: 20 characters

Contains a description of the physical device connected to the object.

Elapsed Active Time

   

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.

Heavy Equip Delay

C,W

Not supported

Range: 0–255 Seconds

Indicates the amount of time that this output point adds to the Accumulated Delay attribute of the Heavy Equipment Controller (HEC) object when this point is started. The next output point is delayed by that amount of time of the HEC Accumulated Delay is not already decremented to zero.

The NAE device’s five internal Heavy Equipment Controller objects (see HED Controller) time their delays independently of one another. For example, HED 1 and HED 4 can count down their delays at the same time.

HED Controller

C,W

Not supported

1–5

Identifies the Heavy Equipment Controller (HEC) object managing the delays.

The NAE device has five internal Heavy Equipment Controller objects for use by BO and Multistate Output (MO) objects. The BO and MO objects reference the heavy equipment delay (HED) controller objects by number (1-5).

All BO and MO objects on an NAE share the five internal HED controller objects. For example, if BO1 and MO3 on NAE-1 reference HED controller 1, they are using the same HED controller.

Inactive Text

   

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.

For example, if the physical output is connected to a switch contact, then the Inactive Text attribute is assigned a value such as Fan 1 Off. If either the Inactive Text or Active Text attribute is present, then both are present.

Intrinsic Alarming Defined

C

Not supported

False

True

Enables the definition of the intrinsic alarm related attributes. For detailed information, see BACnet Intrinsic Alarming.

Min Off Time

C,W

W

0–604,800

Units = seconds

Represents the fewest number of seconds Present Value remains in the Inactive state after entering the Inactive state.

Min On Time

C,W

W

0–604,800

Units = seconds

Represents the fewest number of seconds Present Value remains in the Active state after entering the Active state.

Out of Service

 

W

False

True

Used to decouple the object from the physical output. When out of service is True, the object will decouple Present Value and Reliability from the hardware. The Reliability will be writable when Out Of Service is True. Not all devices support setting this attribute to True.

Polarity

   

Normal, Reverse

Indicates the relationship between the physical state of the output and the logical state represented by Present Value. If the Polarity attribute is Normal, then the Active state of the Present Value attribute is also the Active or On state of the physical output as long as Out of Service is False. If the Polarity attribute is Reverse, then the Active state of the Present Value attribute is in the Inactive or Off state of the physical output as long as Out of Service is False. If Out of Service is False for a constant physical output state, a change in the Polarity attribute produces a change in Present Value. If Out of Service is True, the Polarity attribute has no effect on Present Value. The N2 Polarity attribute is always Normal.

Present Value

D,R,W

D,R,W

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

Priority Array

      Lists values of the object in level of importance.

Reliability

   

No Fault Detected (Reliable), No Output, Open Loop, Shorted Loop, Unreliable Other, Communication Failure

Indicates whether the Present Value is unreliable and why. When Out of Service is True, the Reliability may be written directly.

State Count Reset

W

B, W

 

Represents the date and time the COS Count attribute was last set to a zero value. If the COS Time, Change of State Count, or State Count Reset attribute is present, all of these attributes are present.

States Text

C,W

    Indicates the displayed strings for the Present Value.

States Text Error Status

One state from a set   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 Flags

   

In Alarm, Fault, Overridden, Out of Service

Represents four true or false flags that indicate the general health of an analog output. Three flags are associated with the values of other attributes of the object.

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 is decoupled from the hardware output because operator intervention provided a different value or local override is active.

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

 

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.
