5 Get V Reading
valid BOOL Indicates that the value
attribute contains a valid
value. 0 = invalid
1 = valid
(invalid: e.g., sensor is out of its
specified range)
6 Get V Value INT or REAL Analog input value. The corrected, converted, calibrated
final value of the sensor.
→ "Semantics" section
7 Get V Status BYTE Alarm and warning state of
this object instance. = 0
10 Get NV Full scale INT or REAL The value of full scale for
the sensor. [default] = maximum allowable value
for the data type
25 Set NV Safe state USINT Specifies the behavior for
the value for states other
than execute. → "Semantics" section below
[default] = 0
26 Set NV Safe value INT or speci-
fied by data
type
The Value to be used for
safe state = safe value → "Semantics" section below
[default] = 0
32 Get NV Overrange INT or REAL 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 Under-
range INT or REAL Specifies the lowest valid
value. The value below which attribute
reading valid
is set to invalid.
[default] = minimum allowable value
for the data type
