Protocol Overview

Schneider Electric M580 and M340 support EtherNet/IP via BMXNOE0110 or BMXNOE01P0200 modules. Unity Pro/Control Expert provides EtherNet/IP scanner configuration.

When to Use EtherNet/IP

Choose EtherNet/IP for Rockwell/Allen-Bradley systems, North American facilities, or when standardizing on CIP family protocols.

Schneider Electric Hardware Requirements

Compatible Communication Modules

BMXNOE0110 (M340 Ethernet/IP + Modbus TCP)
BMXNOE01P0200 (M580 Ethernet/IP)
TM3XTRA1 (TM3 EtherNet/IP adapter)

Wiring Details

Network Setup

100Mbps Ethernet. Scanner mode (master) or adapter mode (slave). Supports DLR with compatible switches.

Configuration

Unity Pro: Add BMXNOE0110 to rack. Configure as scanner. Import EDS files. Add adapters with I/O assembly configuration. Map to %IW/%QW.

Schneider Electric Software & Programming

Function Blocks & Instructions

Automatic I/O mapping to %IW/%QW
EIP_READ/EIP_WRITE function blocks
Explicit messaging via ETH_PORT_CTRL

Schneider Electric Code Example

// Automatic I/O mapping:
%QW0.0.0 := OutputValue;  // Write to EtherNet/IP device output assembly
InputValue := %IW0.0.0;   // Read from EtherNet/IP device input assembly

// Explicit message:
EIP_READ(
  Enable := TRUE,
  IPAddress := '192.168.1.10',
  Path := '1,0',  // Backplane, slot 0
  ClassID := 4,
  InstanceID := 100,
  AttributeID := 3,
  DataLength := 10,
  => Data => ReadBuffer
);

Schneider Electric-Specific Implementation Notes

BMXNOE0110 provides both EtherNet/IP and Modbus TCP on same module. I/O mapping uses Schneider's %IW/%QW addressing. DLR support for redundancy. Used when Modicon PLC integrates into Rockwell-dominated facility.
