Class Attribute “Revision”
The Fault History Object has a class attribute named “Revision” which has the Attribute Identifier
01
h. This attribute presents the revision of the Fault History Object which is implemented by the de-
vice.
The Data type of this attribute is UINT (16-bit).
Class Attribute “Max Instance”
The Fault History Object has a class attribute named “Max Instance” which has the Attribute Iden-
tifier 02
h. This attribute presents the maximum number of instances that can exist of the Fault His-
tory Object in the device (i.e. the maximum length of the fault history).
The Data type of this attribute is UINT (16-bit).
Class Attribute “Number of Instances”
The Fault History Object has a class attribute named “Number of Instances” which has the Attribute
Identifier 03
h. This attribute presents the number of instances that currently exist of the Fault His-
tory Object in the device.
The Data type of this attribute is UINT (16-bit).
Instance Attribute “FaultCode”
The object has an instance attribute named “FaultCode” which has the Attribute Identifier 01
h. The
data type is USINT (8-bit). The value returns the fault code of a fault entry which is represented by
the Fault History Object instance.
Instance Attribute “FaultID”
The object has an instance attribute named “FaultID” which has the Attribute Identifier 02
h. The data
type is UINT (16-bit). The value returns the fault ID of a fault entry which is represented by the Fault
History Object instance. This value more exactly specifies which kind of fault is in question.
Instance Attribute “FaultYear”
The object has an instance attribute named “FaultYear” which has the Attribute Identifier 03
h. The
data type is UINT (16-bit). The value returns the year in which the fault occurred (according to the
fault history).
Instance Attribute “FaultMonth”
The object has an instance attribute named “FaultMonth” which has the Attribute Identifier 04
h. The
data type is USINT (8-bit). The value returns the month in which the fault occurred (according to the
fault history).
Instance Attribute “FaultDay”
The object has an instance attribute named “FaultDay” which has the Attribute Identifier 05
h. The
data type is USINT (8-bit). The value returns the day-of-month in which the fault occurred (accord-
ing to the fault history).
Instance Attribute “FaultMillisAfterMidnight”
The object has an instance attribute named “FaultMillisAfterMidnight” which has the Attribute
Identifier 06
h. The data type is UDINT (32-bit). The value returns the number of milliseconds after
midnight when the fault is time stamped.
