ControlLogix Controller Example Scattered Read Response Data
The Scattered Read Request message reads the multiple parameters and
returns their values to the destination tag (Scattered_Read_Response).
Figure 6.16 or Figure 6.17 shows the parameter values.
Figure 6.16 Example Scattered Read Response Data for PowerFlex 7-Class Drive
In this message example, the parameters have the following values.
Figure 6.17 Example Scattered Read Response Data 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 Scattered_Read_Response
integer array to a 32-bit integer or REAL tag.
Figure 6.18 shows the ladder
logic used for this example. If the parameter data type is a REAL, then the
destination tag is a REAL. If the parameter data type is a 32-bit integer, then
the destination tag is a DINT. See the drive documentation to determine the
parameter data type (32-bit integer or REAL).
