SLC 500 Controller Example Scattered Write Request Data
In this message example, we use the data table addresses in Figure 6.77 or
Figure 6.80 to store the request values to be written to these drive
parameters.
See DPI Parameter Object on page C-16 (Class code 0x93) or Host DPI
Parameter Object on page C-30 (Class code 0x9F) for parameter
numbering.
Figure 6.77 or Figure 6.80 shows the parameter values.

SLC 500 Controller Example Scattered Write Response Data
In this message example, we use the data table addresses in Figure 6.78 to
store the response values that were written to the requested drive
parameters. Values of ‘0’ indicate no errors occurred.
Figure 6.78 Example Scattered Write Response Data File for PowerFlex 7-Class Drive
The PowerFlex 750-Series drive uses 32-bit integer and REAL parameters.
A COP command must be used to copy the 16-bit integer or REAL values
to the N90 integer array.
Figure 6.79 shows the ladder logic used for this
example. If the parameter data type is a 32-bit integer, the data remains split
into two 16-bit integers since there are no 32-bit integers in the SLC 500
