Figure 5.3 ControlLogix Ladder Logic Example for Drive I/O Control
PowerFlex 40 ControlNet Single Mode Example
This ControlLogix example system consists of a 1756-CNBR/D in Slot 4 communicating on a ControlNet network with a
PowerFlex 40 drive with an installed 22-COMM-C ControlNet adapter. You may substitute the "PowerFlex 40" for a
PowerFlex 400, or a PowerFlex 4 using an External DSI Communicaitons Kit (22-XCOMM-DC-BASE).
The I/O image is as follows:
INPUT (4 INT words)
PowerFlex_40_Drive:I.Data[0] = 1756-CNBR Overhead (Not Used)
PowerFlex_40_Drive:I.Data[1] = 1756-CNBR Overhead (Not Used)
PowerFlex_40_Drive:I.Data[2] = PowerFlex 40 Logic Status
PowerFlex_40_Drive:I.Data[3] = PowerFlex 40 Speed Feedback
OUTPUT (2 INT words)
PowerFlex_40_Drive:O.Data[0] = PowerFlex 40 Logic Command
PowerFlex_40_Drive:O.Data[1] = PowerFlex 40 Speed Reference
Logic Status information rungs are provided for display purposes only. The PowerFlex_40_Drive:I.Data[2].x bits could be
used directly elsewhere in the ladder program.

This rung displays the Speed Feedback word from the PowerFlex 40. Note that it is set in Hz and not in engineering units
like PowerFlex 7-Class drives. For example, "300" equates to 30.0 Hz (the decimal point is always implied).
