Chapter 7 Using Multi-Drive Mode
Main Routine
The Main Routine reads the network Input Image from the scanner, calls the
various drive control subroutines, and writes the network Output Image to the
scanner. See Main Routine
on page 100.

CompactLogix EtherNet/IP Multi-Drive example program with a PowerFlex 525 on EtherNet/IP.
Four PowerFlex 4M drives are daisy-chained to the main PowerFlex 525 using their RJ45 ports (RS-485). In this mode,
up to ve PowerFlex drives can exist on one EtherNet/IP node.
This rung retrieves the Logic Status and Feedback data for all ve drives from the scanner (DINTs), and moves it to
specic INT tags for use elsewhere in the ladder program. The input image is as follows:
Drive_Input_Image[2] and Drive_Input_Image[3] = Drive 0 Logic Status and Feedback
Drive_Input_Image[4] and Drive_Input_Image[5] = Drive 1 Logic Status and Feedback
Drive_Input_Image[6] and Drive_Input_Image[7] = Drive 2 Logic Status and Feedback
Drive_Input_Image[8] and Drive_Input_Image[9] = Drive 3 Logic Status and Feedback
Drive_Input_Image[10] and Drive_Input_Image[11] = Drive 4 Logic Status and 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 Reference
Drive_Output_Image[2] and Drive_Output_Image[3] = Drive 0 Logic Command and Reference
Drive_Output_Image[4] and Drive_Output_Image[5] = Drive 0 Logic Command and Reference
Drive_Output_Image[6] and Drive_Output_Image[7] = Drive 0 Logic Command and Reference
Drive_Output_Image[8] and Drive_Output_Image[9] = Drive 0 Logic Command and Reference
