In this example, the parameters have the following values.
Figure 6.57 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 command must be used to copy the N60 integer array to a 16-bit
integer or floating tag.
Figure 6.58 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 SLC 500
controller. If the parameter data type is a REAL, then the destination tag is a
floating point. In this case, the value must first be swapped with the high
and low 16-bit integers, and then the two integers copied (COP) into a
floating point address. See the drive documentation to determine the
parameter data type (32-bit integer or REAL).
