Common Attributes - Metasys - LIT-12011964 - Software Application - SCT System Configuration Tool - 16.0

Contains a freely definable user-friendly name for the object that is independent of the Item Reference or the location of the object in the physical network. The Name is used as the label in the All Items navigation tree. The Name is shown in alarm reports, the event and audit viewers, and in summaries. The Name does not need to be unique to the site unless the name is used as the BACnet Object Name. When the name is used as the BACnet Object Name, it must be unique among the BACnet Object Names in the device (if it is not a Device object) or unique among the other device objects (if it is a Device object). ].

The following characters cannot be used in an object name:

@ ? * # [ ] " ‘ “ ” \ : / < > | $ . , ' _ &

The Name defaults to the object identifier you used during manual object creation, but can be edited later. For integrated BACnet objects, the name defaults to the BACnet Object Name in the remote BACnet device. For integrated N1 network objects, the name defaults to the System.Object Name in the Network Communication Module (NCM).

Example: ConferenceCenter-Room2-SpaceSetPoint

For devices, both the Computer Name and Name attributes default to the object identifier you used during manual object creation. But do not confuse the Computer Name attribute with the Name attribute. Changing the NAE Name attribute does not impact the object references or network communication with other devices on the site.

Changing the Computer Name online breaks any existing references between the NAE object and other objects on the site, and may break the existing network connection to other devices on the network. We do not recommend changing the Computer Name online. If you change the Computer Name attribute in the SCT (right-click the NAE in the navigation tree and select Rename), both the Computer Name and Name attributes are changed to the new name you select. The Item Reference then updates to show the new Computer Name.

Contains a user-defined description of the object or, for some integrations, the device description. After the description is defined by the user, the description is not read from the device again.

Classifies the object by the category of system or equipment that it monitors to aid in the determination of user access privileges and alarm routing.

Examples: HVAC, Fire, Security

Indicates the Object Type as displayed in the software and as exposed to a BACnet network.

Example: AI (Analog Input)

Indicates the date of the last successful archive of object instances. The value of this attribute is valid if a valid archive exists and during the archive download process. The value of this attribute is 0xFF at all other times.

Indicates the Object Name as exposed to a BACnet network. This attribute is equivalent to the Item Reference without the site identifier. You cannot edit this attribute, but it changes when the Item Reference attribute updates.

In addition, you can change the Object Name attribute by editing the User Name attribute and setting the User Name Is BACnet Obj Name attribute to True.

Example: NAE3/N2 Trunk1.AHU4.Supply Temp

Indicates the instance number of the Object Type used in the BACnet Object ID as exposed to a BACnet network. The object ID must be unique within the host device. The object ID of the Device object must be unique within the BACnet network.

Controls whether the object’s User Name attribute is also the Object Name attribute. The Object Name attribute is not writable, so the only way to change the Object Name attribute is to edit the User Name attribute and set the User Name Is BACnet Obj Name attribute to True.

Displays the version number of the object software code. As the functionality of objects is enhanced, the version numbers are incremented.

Example: 3.1 where 3 is the major revision and 1 is a minor revision
