View BACnet objects and their intrinsic alarming in Boss’nX

The discovered objects window in Boss’nX lists the BACnet objects of a device: type, instance, name, unit and intrinsic alarming state. It shows the information obtained during discovery: it displays no live measurement and controls no object.

Intended for administrators and installers with Manage BACnet. To use an object in a component, then follow the configuration of a BACnet datapoint.

Open the objects window

1. In the relevant supervision, open Menu → BACnet devices, in the Integration family; if it is folded, click its title first. On a tablet or phone, Menu is at the bottom of the screen, to the right of the bar.
2. Find the device, then click the View discovered objects eye on its row or card. If the eye is missing, run or troubleshoot discovery.
3. Check the device name at the top of the window.
4. Scroll through the list. On a narrow screen, also scroll the table horizontally to see the last columns.
5. Leave with Close, at the bottom, or the cross at the top.

After a new discovery, close and reopen this window to view the new result.

Search for an object

1. Enter a name, a description or an instance in Search (name, description, instance…).
2. To limit the list to one type, select it in the All types list, which shows the number of objects per type.
3. If an object seems to be missing, empty the search field and set All types again.

If the object is still missing, check the discovery result, in particular the Partial badge, before concluding that it has disappeared.

Read a row

Column	What it tells you
Type	AI/AO/AV: analog input, output or value; BI/BO/BV: binary input, output or value; MI/MO/MV: multistate input, output or value.
Instance	The instance of this object. The type and the instance together identify the object; the device instance is in the device list.
Name	The discovered name, or (no name) if it is not filled in. A description may appear under the name.
Units	The available unit, for example °C. A dash means that no unit is provided for the object, not that the measured value is zero.
Alarm	The configuration state of intrinsic reporting obtained during discovery, described below.

The objects are sorted by type, then by instance. The window has no instantaneous value column: to view a measurement or act on the installation, use the supervision component configured for this purpose. The installer can point it out to you if necessary.

Understand the Alarm column

Intrinsic reporting is the BACnet mechanism by which the device itself evaluates an object’s alarm conditions and sends the corresponding notifications. The Alarm column shows how it was configured at the time of discovery:

• Green chip Intrinsic alarming active: the object’s intrinsic reporting was enabled. The chip describes a configuration, not an alarm triggered right now.
• Grey chip Capable, not configured on device: the object supports this reporting, without an active configuration in the received result.
• Dash: no supported intrinsic reporting is identified for this object in this result. Other alarms may exist elsewhere in the installation.

These chips are not switches: the window does not let you enable, disable or acknowledge an alarm. Before changing the device parameters because of a color, check the objective with the installer.

Troubleshooting

Need or symptom	Action
Read the current temperature	This window identifies the objects and their characteristics; it gives no current measurement. Open the intended supervision component; if you do not know which one to use, ask the installer or support.
A name, a unit or an object is missing	Remove the filters, then check the last discovery. If it is partial or failed, follow discovery troubleshooting.
Change the device’s address or instance	Close the window and follow edit the BACnet declaration. The object rows are not used to configure components.

Contact support

If the result remains incomplete after these checks, write to support@can-nx.com with the device name, the type and instance you are looking for, the displayed message and the attempts already made.
