MicroLogix 1100/1400 Controller Example Scattered Write Request Data
In this message example, we use the data table addresses in Figure 6.93 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 6.93 or Figure 6.96 shows the parameter values.

MicroLogix 1100/1400 Controller Example Scattered Write Response Data
In this message example, we use the data table addresses in Figure 6.94 to
store the response values that were written to the requested drive
parameters. Values of ‘0’ indicate no errors occurred.
Figure 6.94 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 or CPW command must be used to copy the 16-bit integer or REAL
values to the N90 integer array.
Figure 6.95 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
