ERR_CLASS_DEVICE = 0

Device

This Error Class pertains to circumstances that affect the functioning of an entire BACnet device. The presence of one of these

Device busy

A service request has been temporarily declined because the addressed BACnet device expects to be involved in higher priority processing for a time in excess of the usual request/confirm timeout period.

Configuration in progress

A service request has been temporarily declined because the addressed BACnet device is in the process of being configured, either by means local to the device or by means of other protocol services.

Operational problem

A service request has been declined because the addressed BACnet device has detected an operational problem that prevents it from carrying out the requested service.

Other

This error code is returned for a reason other than any of those previously enumerated for this Error Class.

ERR_CLASS_OBJECT = 1

Object

This Error Class pertains to problems related to identifying, accessing, and manipulating BACnet objects, whether BACnet defined or not. Since these errors generally apply to individual object characteristics, they do not necessarily signal that an entire service request has failed.

Dynamic creation not supported

An attempt has been made to create an object using an object type that cannot be created dynamically.

No alarm configured

The BACnet object referenced by the service does not support, or is not configured for, event generation.

Object not found

A search of the addressed BACnet device's object database has failed to find any objects of the object type specified in the service request.

Object deletion denied

An attempt has been made to delete an object that cannot be deleted or is currently protected from deletion.

Object ID already exists

An attempt has been made to create a new object using an object identifier already in use.

Read access denied

An attempt has been made to read the properties of an object defined as inaccessible through the BACnet protocol read services.

Unknown object

An Object_Identifier has been specified for an object that does not exist in the object database of the addressed BACnet device.

Unsupported object type

An object type has been specified in a service parameter that is unknown or unsupported in the addressed BACnet device.

Other

This error code is returned for a reason other than any of those previously enumerated for this Error Class.

ERR_CLASS_PROPERTY = 2

Property

This Error Class pertains to problems related to identifying, accessing, and manipulating the properties of BACnet objects, whether BACnet-defined or not. Since these errors generally apply to individual property characteristics, they do not necessarily signal that an entire service request has failed.

Character set not supported

A character string value was encountered that is not a supported character set.

Datatype not supported

The data is of, or contains, a datatype not supported by this instance of this property.

Invalid selection criteria

A property has been referenced with a datatype inconsistent with the 'Comparison Value' specified in an 'Object Selection Criteria' service parameter. This error would arise, for example, if an analog property were compared against a Boolean constant, or vice-versa.

An attempt was made to access an array property using an array index that is outside the range permitted for this array.

Invalid data type

The datatype of a property value specified in a service parameter does not match the datatype of the property referenced by the specified Property_Identifier.

Not COV property

The property is not conveyed by COV notification.

Optional functionality not supported

An attempt has been made to write a value to a property that would require the device to exhibit non-supported optional functionality.

Property is not an array

An attempt has been made to access a property as an array and that property does not have an array datatype.

Read access denied

An attempt has been made to read a property defined as inaccessible through the BACnet protocol read services.

Unknown property

A Property_Identifier has been specified in a service parameter that is unknown or unsupported in the addressed BACnet device for objects of the referenced object type.

Value out of range

An attempt has been made to write to a property with a value that is outside the range of values defined for the property.

Write access denied

An attempt has been made to write to a property defined as inaccessible through the BACnet protocol write services.

Other

This error code is returned for a reason other than any of those previously enumerated for this Error Class.

ERR_CLASS_RESOURCES = 3

Resources

This Error Class pertains to problems related to the resources of a BACnet device that affect its capacity to carry out protocol service requests.

No space for object

An attempt to create an object has failed because not enough dynamic memory space exists in the addressed BACnet device.

No space for element

An attempt to add an element to a list has failed because not enough dynamic memory space exists in the addressed BACnet device.

No space to write property

An attempt to write a property has failed because not enough dynamic memory space exists in the addressed BACnet device.

Other

This error code is returned for a reason other than any of those previously enumerated for this Error Class.

ERR_CLASS_SECURITY = 4

Security

This Error Class pertains to problems related to security.

Authentication failed

The message being authenticated was not generated by the service provider.

Character set not supported

A character string value was encountered that is not a supported character set.

Other

This error code is returned for a reason other than any of those previously enumerated for this Error Class.

ERR_CLASS_SERVICES = 5

Services

This Error Class pertains to problems related to the execution of protocol service requests, whether BACnet-defined or not. Without exception, these errors signal the inability of the responding BACnet-user to carry out the desired service in its entirety and are thus "fatal."

Character set not supported

A character string value was encountered that is not a supported character set.

COV subscription failed

COV Subscription failed for some reason.

Duplicate name

An attempt has been made to write to an Object_Name property with a value that is already in use in a different Object_Name property within the device.

Duplicate object ID

An attempt has been made to write to an Object_Identifier property with a value that is already in use in a different Object_Identifier within the same device.

Property is not an array

An attempt has been made to access a property as an array and that property does not have an array datatype.

Service request denied

A request has been made to execute a service for which the requesting BACnet device does not have the appropriate authorization.

Other

This error code is returned for a reason other than any of those previously enumerated for this Error Class.

REJECT_OTHER = 0

Other

Generated in response to a confirmed request APDU that contains a syntax error for which an error code has not been explicitly defined.

REJECT_BUFFER_OVERFLOW = 1

Buffer overflow

A buffer capacity has been exceeded.

REJECT_INCONSISTENT_PARAMS = 2

Inconsistent parameters

Generated in response to a confirmed request APDU that omits a conditional service argument that should be present or contains a conditional service argument that should not be present. This condition could also elicit a Reject PDU with a Reject Reason of INVALID_TAG.

REJECT_INVALID_DATA_TYPE = 3

REJECT_INVALID_TAG = 4

Invalid tag

While parsing a message, an invalid tag was encountered. Since an invalid tag could confuse the parsing logic, any of the following Reject Reasons may also be generated in response to a confirmed request containing an invalid tag: INCONSISTENT_PARAMETERS, INVALID_PARAMETER_DATA_TYPE, MISSING_REQUIRED_PARAMETER, and TOO_MANY_ARGUMENTS.
