In this example, the parameters have the following values.

Figure 6.89 Example Scattered Read Response Data File for PowerFlex 750-Series

Drive

The PowerFlex 750-Series drive uses 32-bit integer and REAL parameters.
A COP or CPW command must be used to copy the N60 integer array to a
16-bit integer or floating tag.

Figure 6.90

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 because there are no 32-bit integers in the
MicroLogix 1100/1400 controller. If the parameter data type is a REAL,
then the destination tag is a floating point. See the drive documentation to
determine the parameter data type (32-bit integer or REAL).
