The ladder example provided in this chapter is based on a 1769-SM1 in
slot 1 with three PowerFlex 70 drives connected (one per channel). The
ladder example demonstrates the following for each channel (drive):
• Use Logic Command bits to control the drive (for example, start,
stop, etc.)
• Send a Reference to the drive
• Obtain status information from the drive (for example, Logic Status,
Feedback, etc.)
• Writing and reading Datalinks
(Figure 5.1).
