CompactLogix DeviceNet Multi-drive example program with a PowerFlex 525 and DeviceNet adapter at node address 1.
Four PowerFlex 4M drives are daisy-chained to the main PowerFlex 525 using their RJ45 ports (RS-485). In this mode,
up to five PowerFlex drives can exist on one DeviceNet node.
This run enables the scanner (changes the scanner to RUN mode).
This rung retrieves the Logic Status and Feedback data for all five drives from the scanner (DINTs), and moves it 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 Feedback
Drive_Input_Image[2] and Drive_Input_Image[3] = Drive 1 Logic Status and Feedback
Drive_Input_Image[4] and Drive_Input_Image[5] = Drive 2 Logic Status and Feedback
Drive_Input_Image[5] and Drive_Input_Image[7] = Drive 3 Logic Status and Feedback
Drive_Input_Image[8] and Drive_Input_Image[9] = 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
