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.
