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.
