SLC 500 Controller Example COP Message to Write Multiple Parameters
A scattered write message is used to write values to multiple parameters.
Values for up to 8 parameters can be written. This write message example
writes the following values to these five parameters.

For PowerFlex 700S or PowerFlex 750-Series drives, if some of the parameters being read are floating point
(REAL) data types, see the ‘Communications’ section in Chapter 1 of the PowerFlex 700S AC Drives Phase II
Control Reference Manual, publication PFLEX-RM003, on how to manipulate REAL data into a proper Float tag.
