5 Get V Reading valid BOOL Indicates that the
value
attribute con-
tains a valid value.
0 = invalid
1 = valid
(invalid: e.g., sensor is out of its
specified range)
6 Get V Value INT or specified
by data type Analog input value The corrected, converted, calibrated
final value of the sensor.
→ "Semantics" section below.
7 Get V Status BYTE Alarm and warning
state of this object
instance. → "Semantics" section below.
10 Get NV Full Scale INT or specified
by data type The value of full scale
for the sensor. The value of attribute value
corresponding to the full scale
calibrated measurement of the
sensor.
[default] = maximum allowable
value for the data type
25 Set NV Safe state USINT Specifies the be-
havior for the value
for states other than
execute → "Semantics" section below.
[default] = 0
26 Set NV Safe value INT or specified
by data type The value to be used
for safe state = safe
value → "Semantics" section below.
[default] = 0
32 Get NV Overrange INT or specified
by data type Specifies the highest
valid value The value above which attribute
reading valid
is set to invalid.
[default] = maximum allowable
value for the data type
33 Get NV Underrange INT or specified
by data type Specifies the lowest
valid value The value below which attribute
reading valid
is set to invalid.
[default] = minimum allowable value
for the data type
94 Get V Sensor warning Struct of byte Bit definitions of
sensor warnings 0 = [default]
→ "Semantics" section below
95 Get V Sensor alarm Struct of byte Bit definitions of
sensor alarms 0 = [default]
→ "Semantics" section below
96 Get V Status extension BYTE Bit-mapped byte pro-
viding additional sta-
tus bits of an S-Ana-
log sensor instance. 0 = [default]
→ "Semantics" section below
99 Get NV Subclass UINT Identifies a subset of
additional instance
attributes, services
and behaviors. 3 = Capacitance Manometer
100 Set NV Auto Zero Adjust BOOL Used to calibrate the
CDG Zero pressure
value periodically 0 -> deactivated;
1 -> activated [default];
