Multistate Output Attributes - Metasys - LIT-1201793 - Software Application - Metasys Site Management Portal - 12.0.50

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.

Device Type

C,W

W

Limit: 20 characters

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

Heavy Equip Delay

C,W

Not supported

0

Range: 0–255 Seconds

Indicates the amount of time that this output point adds to the Accumulated Delay attribute of the Heavy Equipment Controller 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.

C,W

Not supported

1–5

Identifies the Heavy Equipment Controller object managing the delays.

The NAE device has five internal Heavy Equipment Controller objects for use by Binary Output and Multistate Output objects. The BO and MO objects reference the 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.

Also see Heavy Equip Delay.

Intrinsic Alarming Defined

C

Not supported

False

False

True

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

Number of States

C,W

W

4

2–16

Defines the number of states possible for Present Value.

Out of Service

C,W

W

False

True

Used to decouple the object from the physical output. When Out of Service is True, the object decouples 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.

Present Value

D,R,W

D,R,W

States Text attribute identifies the value set for this attribute.

Indicates the current value of the output as one of n states, where n is the number of states defined in Number of States.

Priority Array

Lists object commands in level of importance.

Reliability

Reliable

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

Uses Reliability (Set 503).

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

State Text

Off Low

Med Hi

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

Off Low

Med Hi

Indicates the displayed strings for the Present Value.

States Text Error Status

OK

Out of Memory: Indicates that memory overrun occurred while the systems was adding custom enumeration for state text from the field device to the user dictionary.

OK: The addition of custom enumeration for state text from the field device to the user dictionary is successful, and state text from the device can be used.

Specifies the status of States Text on the supervisory device. This attribute cannot be archived or configured.

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 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

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.
