Parameter-specific list
16
FP Max Decimals Bit 0
These four bits are used on REAL parameters only. They indicate the maximum
number of decimal places to be displayed for small values. A value of 0 indicates
to not limit the number of decimal places used.
17
FP Max Decimals Bit 1
18
FP Max Decimals Bit 2
19
FP Max Decimals Bit 1
20
Extended Parameter
Reference
0 = Not an Extended Parameter Reference
1 = Extended Parameter Reference
An Extended Parameter Reference contains a reference to another parameter.
The value is formatted the same as an analog mode Indirect Selector parameter
(SSpppp, where SS = slot number of device to which this Extended Parameter
Reference is pointing, and pppp = number of the parameter or diagnostic item to
which this Extended Parameter Reference is pointing). Note that an Extended
Parameter Reference can only select parameters unlike an Indirect Selector. An
Extended Parameter Reference could be used to configure a Datalink or show
the source of a Reference (among other uses).
21
Uses Rating Table Object
This parameter has rating-dependent defaults and limits that can be obtained
from the Rating Table Object. The Offline Read Full will include the default value
for the smallest rating and limits that will accommodate the full range of values
allowed in the family of devices using this particular combination of Family Code
and Config Code. The Online Read Full will include the rating-dependent default
and limit values for this particular combination of Family Code, Config Code, and
Rating Code.
22
Writable Referenced
Parameter
This bit must be zero unless the parameter is an Extended Parameter
Reference. If the parameter is an Extended Parameter Reference, then:
0 = The referenced parameter may be read-only or writable.
1 = The referenced parameter must always be writable (including while running).
23
Disallow Zero
This bit must be zero unless the parameter is an Indirect Selector or Extended
Parameter Reference. If the parameter is an Indirect Selector or Extended
Parameter Reference, then:
0 = Allow zero
1 = Disallow zero
If this bit is cleared (indicating that a value of zero is allowed), the device must
support the “Zero Text” parameter attribute so that a software tool or HIM can
obtain text from the Zero Text parameter attribute.
If this bit is set (indicating that a value of zero is disallowed), a software tool or
HIM will not allow the user to enter a value of zero.
24
Datalink Out
This bit is used by offline tools and indicates that this is a Datalink Out
parameter. Bit 20 must also be set.
25
Datalink In
This bit is used by offline tools and indicates that this is a Datalink In parameter.
Bits 20 and 22 must also be set.
