Schneider BMENOC0301 M580 Ethernet Module

Schneider BMENOC0301 Modicon M580 Network Module

Product Introduction

The BMENOC0301 serves as a dedicated Ethernet communication module for the Schneider Electric Modicon M580 platform. Specifically, it enables process and control data exchange across plant networks. This module fits directly into the main rack using an Ethernet and X-bus slot. As a result, it extends the native networking capability of M580 controllers without replacing the CPU. Furthermore, the BMENOC0301 supports both standalone and redundant architectures. It works with M580 standalone CPUs, redundant CPUs, and safety CPUs. Typical applications include SCADA integration, distributed I/O scanning, and device-level messaging.

Technical Specifications

Port Configuration and Compatibility

Three Ethernet RJ45 ports operate at 10/100 Mbit/s using double shielded twisted pair cabling. These ports connect through the Ethernet backplane of an X80 rack. The module occupies a single slot in the main rack. Up to 4 modules can be installed per rack, allowing flexible network segmentation. Compatible controllers include Modicon M580 standalone CPUs (BMEP58 series), redundant CPUs (BMEH58 series), and safety CPUs (BMEP582 and BMEH582 non-interfering type 1). It also requires an X80 rack with an Ethernet backplane.

Communication Services

The module provides a broad set of embedded services. For instance, it includes an EtherNet/IP I/O scanner and Modbus TCP I/O scanner for real-time data exchange. It also supports Modbus TCP messaging for peer-to-peer communication. Bandwidth management allows traffic prioritization across critical and non-critical data. The FDR server function simplifies device replacement by automatically reassigning IP addresses. Meanwhile, SNMP support enables network administration and monitoring. RSTP and port mirroring improve network resilience and diagnostics. Additionally, an embedded multiport switch reduces external wiring needs. A built-in web server assists with commissioning, operation, and maintenance tasks.

Electrical and Signalling

The module draws power internally from the rack backplane. Current consumption is 900 mA at 3.3 V DC for product version 13 and later. Earlier versions consume 1800 mA at 3.3 V DC. Four LEDs provide local status indication. A green RUN LED shows processor activity, while a red ERR LED signals faults. Two additional LEDs display Ethernet MS configuration status and Eth NS network status.

Mechanical and Environmental Parameters

The module measures 32 mm wide, 103.7 mm high, and 86 mm long. Product weight is approximately 0.2 kg. The IP degree of protection is IP20, suitable for cabinet installation. Ambient air temperature for operation ranges from 0°C to +60°C. The product carries CE marking and complies with the 2014/35/EU low voltage directive. It also meets the 2014/30/EU electromagnetic compatibility directive.

Installation Guide

Step 1: Prepare the Rack

First, disconnect all power sources before starting installation. Verify that the X80 rack features an Ethernet backplane. Remove the protective cover from the target Ethernet and X-bus slot.

Step 2: Insert the Module

Next, align the BMENOC0301 with the guide rails on the selected slot. Push the module firmly into the backplane connector until it seats completely.

Step 3: Secure and Connect

Once seated, tighten the retaining screw at the top of the module. Connect Ethernet cables to the RJ45 ports as required by the network design. Confirm that cable shielding is properly grounded.

Step 4: Verify Operation

Finally, apply power to the rack and observe the LED indicators. The RUN LED should illuminate green, and the Eth NS LED should show network activity. Configure IP parameters through the web server or programming software.

FAQ

Q: Which controllers are compatible with the BMENOC0301?

A: The module works with Modicon M580 standalone CPUs, redundant CPUs, and non-interfering safety CPUs. Specifically, it supports BMEP58 series, BMEH58 series, BMEP582, and BMEH582 controllers when paired with an Ethernet backplane rack.

Q: How many BMENOC0301 modules can fit in one rack?

A: Each rack accepts up to 4 communication modules. This limit applies per rack, so larger systems can distribute modules across multiple racks for additional network capacity.

Q: What communication protocols does the BMENOC0301 support?

A: The module supports Modbus TCP and EtherNet/IP for both I/O scanning and messaging. It also provides SNMP, RSTP, FDR server, and port mirroring services for network management and resilience.

Q: Does the module require an external power supply?

A: No, the BMENOC0301 draws power directly from the rack backplane. Current consumption is 900 mA at 3.3 V DC for version 13 and later.

Q: What is the FDR server function used for?

A: The FDR server automatically assigns IP addresses to replacement devices. Therefore, maintenance staff can swap a faulty device without manual reconfiguration. This feature reduces downtime during device replacement.
