SLC 500 Controller Example COP Message to Read Multiple Parameters
A scattered read message is used to read the values of multiple parameters.
Up to 8 parameters can be read. This read message example reads the values
of these five parameters in a PowerFlex 7-Class drive:
• Parameter 001 - [Output Freq]
• Parameter 003 - [Output Current]
• Parameter 006 - [Output Voltage]
• Parameter 012 - [DC Bus Voltage]
• Parameter 017 - [Analog In2 Value]
