PLC-5 Controller Example to Write Multiple Parameters

A scattered write message is used to write values to multiple parameters.
Values for up to 19 parameters can be written. This write message example
writes the following values to these five parameters.

Address

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.
