EtherNet/IP Communications Module
8.6.1 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 figure 8.6.

ControlLogix to
The ControlLogix system consists of a 1756-ENBT in slot 5 communicating over Ethernet with a MD65 drive/ MDCOMM-
ENET EtherNet/IP module.
The I/O image is as follows:
INPUT (4 INT words) OUTPUT (2 INT words)
MD65-Demo:I.Data[0] = ENBT Overhead MD65-Demo:I.Data[0] = MD65 Logic Command
MD65-Demo:I.Data[1] = ENBT Overhead MD65-Demo:I.Data[1] = MD65 Reference
MD65-Demo:I.Data[2] = MD65 Logic Status
MD65-Demo:I.Data[3] = MD65 Feedback
Logic Status information rungs are provided for display purposes only. The MD65_Demo: I.Data[2].x.bits could be used
directly elsewhere in the ladder program.
