C-12 DeviceNet Objects
Bit Definitions for Instance Attribute 4
12 Get Full Default Value Same as
attribute 1
The actual value attribute 1, Parameter
Value, should be set to when the user
wants the default for the parameter.
13 Get Full Scaling Multiplier UINT Multiplier for scaling formula.
14 Get Full Scaling Divisor UINT Divisor for scaling formula.
15 Get Full Scaling Base UINT Base for scaling formula.
16 Get Full Scaling Offset UINT Offset for scaling formula.
17 Get Full Multiplier Link UINT Parameter object instance number of
multiplier source.
18 Get Full Divisor Link UINT Parameter object instance number of
base source.
19 Get Full Base Link UINT Parameter object instance number of
offset source.
20 Get Full Offset Link UINT Parameter object instance number of
offset source.
21 Get Full Decimal Precision USINT Specifies number of decimal places to use
when displaying the scaled engineering
value. Also used to determine actual
increment value so that incrementing a
value causes a change in scaled
engineering value to this precision.
Attribute ID
Access
Rule
Stub/Full Name Data Type Description
➀ The access rule is defined in bit 4 of instance attribute 4, the Descriptor. If bit 4 is 0, the access rule is Set and the Parameter Value can be read and
written. If bit 4 is 1, the access rule is Get and the Parameter Value can only be read.
➁ Data type specified in instance attributes 4 (Descriptor), 5 (Data Type), and 6 (Data Size).
Bit Definition Value
0 Supports settable path 0 = Link path cannot 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 presented to
the user in engineering units.
