2.3.2.1 Semantics
This attribute represents the current state of the device. Its value changes as the
state of the device changes. The following values are defined:
Attribute Value State
0 Undefined
1 Self Testing
2 Idle
3 Self-Test Exception
4 Executing
5 Abort
6 Critical Fault
In case of a Self-Test Exception restart the device with a reset out of the box
(Identity Object Class 1, Instance 1, Service 5, Service target value: 1).
A single byte attribute whose value indicates the status of the alarms and warnings
for the device. The device supports the Expanded Mode.
For the Expanded Mode, bit seven of Exception Status attribute is set to one;
exceptions are reported through the communication of this Exception Status at-
tribute, formatted as specified in the table below. In addition, the Exception Detail
attributes are supported. The Exception Status bits are determined by a logical
”OR” of the related Exception Detail bits, as indicated.
Bit Function
0 ALARM/device-common
(The alarm or warning is not specific to the device type or device type manufacturer).
1 ALARM/device-specific
2 ALARM/manufacturer-specific
3 reserved, set to 0
4 WARNING/device-common
5 WARNING/device-specific
6 WARNING/manufacturer-specific

1 Ζ Expanded Method
The formats of these two attributes are identical. Therefore, they are described
together:
Attributes that relate the detailed status of the alarms or warnings associated with
the device. Each attribute is a structure containing three members; these three
members, respectively relate the detailed status of exceptions that are common
(i.e., not device-specific), device-specific and manufacturer-specific. The common
and device-specific detail definitions are defined below. A manufacturer-specific
detail has a length of 1 byte. A SIZE value of one indicates that one byte detail is
defined for the associated exception detail structure.
