Parameter Object
Bit Definitions for Instance Attribute 4
Bit Definition Value
0 Supports settable
path
0 = Link path can not be set.
1 = Link path can be set.
1 Supports
enumerated strings
0 = Enumerated strings are not supported.
1 = Enumerated strings are supported and may be read with
the Get_Enum_String service.
2 Supports scaling 0 = Scaling not supported.
1 = Scaling is supported. The scaling attributes are
implemented and the value presented is in engineering
units.
3 Supports scaling
links
0 = Scaling links not supported.
1 = The values for the scaling attributes may be retrieved
from other parameter object instances.
4 Read only parameter 0 = Parameter value attribute can be written (set) and read
(get). Access rule is set.
1 = Parameter value attribute can only be read. Access rule is
get.
5 Monitor parameter 0 = Parameter value attribute is not updated in real time by
the device.
1 = Parameter value attribute is updated in real time by the
device.
6 Supports extended
precision scaling
0 = Extended precision scaling is not supported.
1 = Extended precision scaling should be implemented and
the value is presented in engineering units.
