7-10 Using Multi-Drive Mode
Figure 7.9 ControlLogix Main Routine
PowerFlex 40 ControlNet Multi-Drive Mode Example
ControlLogix Multi-Drive Mode example program with a PowerFlex 40 on ControlNet (22-COMM-C adapter). In this example,
Four (4) PowerFlex 4 drives are daisy-chained to the main PowerFlex 40 (with installed 22-COMM-C adapter) via their RJ-45
ports (RS-485). In this mode, a total of up to five (5) PowerFlex 4/40/400's can exist as one (1) ControlNet node on the
network.
This rung retrieves the Logic Status and Speed Feedback data for all five (5) drives from the scanner (array of INTs), and
moves them to specific INT tags for use elsewhere in the ladder program. The input image is as follows:
Drive_Input_Image[0] and Drive_Input_Image[1] = Drive 0 Logic Status and Speed Feedback
Drive_Input_Image[2] and Drive_Input_Image[3] = Drive 1 Logic Status and Speed Feedback
Drive_Input_Image[4] and Drive_Input_Image[5] = Drive 2 Logic Status and Speed Feedback
Drive_Input_Image[6] and Drive_Input_Image[7] = Drive 3 Logic Status and Speed Feedback
Drive_Input_Image[8] and Drive_Input_Image[9] = Drive 4 Logic Status and Speed Feedback

This rung writes the output image to the scanner. The output image is as follows:
Drive_Output_Image[0] and Drive_Output_Image[1] = Drive 0 Logic Command and Speed Reference
Drive_Output_Image[2] and Drive_Output_Image[3] = Drive 1 Logic Command and Speed Reference
Drive_Output_Image[4] and Drive_Output_Image[5] = Drive 2 Logic Command and Speed Reference
Drive_Output_Image[6] and Drive_Output_Image[7] = Drive 3 Logic Command and Speed Reference
Drive_Output_Image[8] and Drive_Output_Image[9] = Drive 4 Logic Command and Speed Reference
(Note the length of the COP instruction is "10" because the Destination address is an INT)
