Deviations
 The Temperature correction option [71x,28]
values the DL8000 returns do not map directly
to the DanLoad 6000 program codes (432,
435, etc.) for all values.
 The Pressure correction option [71,x,29]
values the DL8000 returns do not map directly
to the DanLoad 6000 program codes (444,
447, etc.) for all values.

Values and Attributes
[0x22]
A program code value is a number. A program code identifies a variable
(parameter) in DanLoad 6000. This parameter is mapped to DL8000. A
program code value is the value of variable identified by the program code
and can be a number of byte length depending on the program code. A
program code’s attributes are the properties associated with that program
code. Since TAS can request a range of program code values (from those
which are supported) and attributes the response data field is variable field
length.
The following program codes (with their data types) are supported for this
release:
 026 Unit Type (16-bit integer)
 028 Language (8- bit integer)
 042 Last Transaction Number(16-bit integer)
 043 Last Batch No(16-bit integer)
 044 Additive Unit(16-bit integer)
 046 Density/Gravity Scale (8- bit integer)
 067/070/073/076 Component 1 to 4 Meter Nos.(16-bit integer)
 457/459/461/463 Backup density(32-bit integer)
