Using Explicit Messaging Chapter 6
Example Ladder Logic Program to Read Multiple Parameters
A Scattered Read message is used to read the values of multiple parameters. This
CompactLogix controller read message example reads the values of these five 16-
bit parameters in a PowerFlex 525 drive:
• Host parameter b001[Output Freq]
• Host parameter b003 [Output Current]
• Host parameter b004 [Output Voltage]
• Host parameter b005 [DC Bus Voltage]
• Host parameter b017 [Output Power]
See DPI Parameter Object
on page 145 (Class code 0x93) for parameter
numbering.
