26 Not a Link Source 0 = Can be the source end of a link.
1 = Cannot be the source end of a link.
27 Enhanced Bit ENUM Parameter supports enhanced bit ENUMs.
28 Enhanced ENUM Parameter supports enhanced ENUMs.
29 Uses DPI Limits Object Parameter uses the DPI Limits Object.
Intelligent offline tools use the Limits Object to select limits and units.
30 Extended Descriptor Parameter uses Extended Descriptor bits, which can be obtained by reading the DPI Extended Descriptor attribute for this parameter.
31 Always Upload/Download Always include Parameter in uploads and downloads.

11 Indirect Type 10 Undefined (Instance 0xFFF5)
12 Indirect Type 11 Undefined (Instance 0xFFF4)
13 Indirect Type 12 Undefined (Instance 0xFFF3)
14 Indirect Type 13 Undefined (Instance 0xFFF2)
15 Indirect Type 14 Parameter-specific list
16 FP Max Decimals Bit 0 These 4-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 that there is no limit to 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 pointed. 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).
