7.4.5.1.1 Offset — An attribute which specifies the
amount of offset correction being applied to derive the
value of the “Value” attribute (inherited) of the object
instance. It is expressed in terms of the units specified
by the “DataUnits” attribute.
7.4.5.1.2 Gain — An attribute which is used to define
the range of the “Value” attribute (inherited) of the
object instance. The method of conveying this range
with this attribute is beyond the scope of this document.
7.4.5.1.3 DataType — An attribute which defines the
format of the data associated with “Value” attribute
(inherited) of the object instance.
7.4.5.1.4 DataUnits — An attribute which defines the
current units associated with “Value” attribute
(inherited) of the object instance.
7.4.5.1.5 SafeState — An attribute which defines the
Value (inherited attribute) to be reported by the object
instance when it is in a non-OPERATING state. The
enumeration of the SafeState attribute is given in Table
39.

7.4.5.1.6 EnableReportDelta — An attribute which
enables the reporting of the attribute “Value” based on
the “ReportDelta” attribute value (see below); a value
of TRUE signifies that reporting using the
“ReportDelta” method is enabled.
7.4.5.1.7 ReportDelta — The value of this attribute
indicates the amount by which the sensor value
(indicated by the “Value” attribute (inherited)) must
change before it is published. When the value of the
EnableReportDelta attribute indicates that this method
of reporting is “enabled”, and when the value of the
“Value” attribute changes by an amount in excess of the
amount indicated by the ReportDelta attribute value, the
object will publish the Value attribute.
7.4.5.1.8 EnableReportROC — The Enable
ReportROC (rate of change) attribute enables the
reporting of the attribute “Value” based on the
“ReportROC” attribute value (see below); a value of
TRUE signifies that reporting using the rate of change
method is enabled.
7.4.5.1.9 ReportROC — The value of this attribute
indicates the rate by which the sensor value (indicated
by the “Value” attribute (inherited)) must change before
it is published. The attribute value context is
DataUnits/Time; the specific context of DataUnits is
defined in the DataUnits attribute, while the unit of
Time is context-specific. When the value of the
EnableReportDelta attribute indicates that this method
of reporting is “enabled”, and when the value of the
“Value” attribute changes at a rate in excess of the
amount indicated by the ReportDelta attribute value, the
object will publish the Value attribute.
7.4.5.1.10 AlarmTripPointHigh — An attribute which
specifies the value above which the object instance
“Value” attribute (inherited) value must be to generate
an alarm status indication. The behavior associated with
the generation of an alarm status indication (beyond
that described in Section 7.4.1.3) is beyond the scope of
this document.
7.4.5.1.11 AlarmTripPointLow — An attribute which
specifies the value below which the object instance
“Value” attribute (inherited) value must be to generate
an alarm status indication. The behavior associated with
the generation of an alarm status indication (beyond
that described in Section 7.4.1.3) is beyond the scope of
this document.
7.4.5.1.12 AlarmHystersis — An attribute which
specifies the amount of hysteresis to be applied in the
clearing of an alarm condition. For example: a Trip
Point High value of 100 with a hysteresis value of 2
will result in an exception condition being set when the
Value attribute exceeds 100 in the positive direction
and cleared when the Value attribute exceeds 98 in the
negative direction. Similarly, a Trip Point Low value of
100 with a hysteresis value of 2 will result in an
exception condition being set when the Value attribute
exceeds 100 in the negative direction and cleared when
the Value attribute exceeds 102 in the positive
direction. The behavior associated with the generation
and clearing of exception conditions is beyond the
scope of this document.
7.4.5.1.13 WarningTripPointHigh — An attribute
which specifies the value above which the object
instance “Value” attribute (inherited) value must be to
generate a warning status indication. The behavior
associated with the generation of a warning status
indication is beyond the scope of this document.
7.4.5.1.14 WarningTripPointLow — An attribute
which specifies the value below which the object
instance “Value” attribute (inherited) value must be to
generate a warning status indication. The behavior
associated with the generation of a warning status
indication is beyond the scope of this document.

7.4.5.1.15 WarningHystersis — An attribute which specifies the amount of hysteresis to be applied in the clearing

conditions is beyond the scope of this document.
