Introduction
The BMENOC0301/11 Ethernet communications module is installed on a local Ethernet backplane in the Modicon M580 system. With the Ethernet backplane enabled, the BMENOC0301/11 provides access to the Modicon M580 CPU's network (through the external ports of the CPU).
NOTE: Do not mount the BMENOC0301/11 module on a BMX (X Bus only) backplane. The module will only power up on a BME (Ethernet) backplane. Refer to the rack descriptions in the Modicon X80 Racks and Power Supplies, Hardware, Reference Manual.
Ruggedized Version
The BMENOC0301C and BMENOC0311C (coated) equipment are respectively the ruggedized versions of the BMENOC0301 and BMENOC0311 (standard) equipment. They can be used at standard temperatures and in harsh chemical environments.
For more information, refer to chapter Installation in More Severe Environments.
Altitude Operating Conditions
The characteristics apply to the modules BMENOC0301/11 and BMENOC0301C/11C for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.
BMENOC0301/11 and PlantStruxure
PlantStruxure is a Schneider Electric program designed to address the key challenges of many different types of users, including plant managers, operations managers, engineers, maintenance teams, and operators, by delivering a system that is scalable, flexible, integrated, and collaborative.
This document presents one of the PlantStruxure features, using Ethernet as the backbone around the Modicon M580 offer, in which an M580 local rack communicates with M580 RIO drops and distributed equipment in the same network.

SERVICE port (ETH 1)
Use the RJ45 Ethernet connector for a SERVICE port.
NOTE: Refer to the service port configuration.

DEVICE NETWORK port (ETH 2)
These RJ45 DEVICE NETWORK ports provide:
  • Ethernet communications (10/100 Mbps)
  • connections for distributed device communications
  • cable redundancy through a daisy chain loop architecture

DEVICE NETWORK port (ETH 3)
To keep dust out of unused Ethernet ports, cover the ports with the stopper:
Dual-Bus Backplane Connector
The dual-bus interface on the back of the BMENOC0301/11 module connects to the X Bus and Ethernet bus connectors on the Ethernet backplane when you mount the module in the rack. The module, therefore, supports both X Bus and Ethernet communications over the backplane:
Bus
Description
X Bus
The BMENOC0301/11 module uses X Bus communications on the Ethernet backplane to obtain and exchange these data through the CPU:
  • configuration data for the BMENOC0301/11 module
  • application and diagnostic data
Ethernet
The BMENOC0301/11 module uses the Ethernet bus on the Ethernet backplane to manage connectivity to the BMENOC0301/11 module:
  • The BMENOC0301/11 module provides Ethernet connectivity to the CPU.
  • The BMENOC0301/11 module communicates with the Ethernet communication modules on the local rack.
  • The BMENOC0301/11 module communicates with network devices that are attached to the external ports of the CPU.
