Schneider BMEH584040 Modicon M580 Redundant Processor Module 16MB

Product Overview

When your process demands uninterrupted control, the Schneider BMEH584040 redundant processor module delivers the reliability you need. Part of the Modicon M580 family, this module is engineered for high-availability applications where downtime is not an option. With 16 MB of program memory and support for up to 61 Ethernet devices, it provides a robust foundation for complex automation architectures.

Technical Specifications

The BMEH584040 offers 16 MB of integrated RAM for program storage and 2048 kB for data, plus an expandable flash memory with 4 GB data storage. It supports up to 16 remote I/O stations with X80 and Quantum drops, and up to 64 distributed equipment nodes. Communication includes one Ethernet TCP/IP service port, two Ethernet TCP/IP device networks, one USB mini B port, and one Ethernet HSBY port for hot standby links. The module consumes 360 mA at 24 V DC and is rated for operation from 32 to 140 °F (0 to 60 °C). It carries CE marking and is Achilles certified for cybersecurity, with features like DoS prevention, IPSec, SNMP logging, and an embedded firewall.

Industry Applications

In process control environments such as oil and gas, water treatment, or power generation, the BMEH584040 ensures continuous operation even during processor maintenance or upgrades. Its redundant architecture allows one processor to take over seamlessly if the primary fails, minimizing production losses. For discrete manufacturing with high-speed lines, the module handles 40 K instructions per ms (100% Boolean) to maintain tight cycle times.

Installation & Setup Guidance

Install the BMEH584040 into a compatible Modicon M580 rack using the internal power supply via rack connection. Ensure proper grounding and follow standard ESD precautions. The module provides 14 status LEDs for quick diagnostics, including RUN, ERR, I/O fault, and hot standby status. Use the USB mini B port for local programming access. For redundant configurations, set processor IDs A and B via the dedicated LEDs and verify the HSBY link status.

Maintenance & Reliability

With an MTBF of 650,000 hours, the BMEH584040 offers exceptional long-term reliability. Routine inspection should focus on LED status indicators and ambient temperature conditions (0 to 60 °C). The module is IP20 rated, so keep it in a clean, dry enclosure. No internal maintenance is required; periodic firmware updates via the Ethernet port help maintain cybersecurity posture. The module supports secure communication (HTTPS) and audit trail logging for compliance.

Compatibility & Integration

The BMEH584040 integrates seamlessly with Modicon M580 racks and supports up to 16 remote I/O stations combining X80 and Quantum I/O drops. It can manage up to 8 AS-Interface modules and 16 Ethernet communication modules. Communication services include RIO scanner and DIO scanner. The module is TAA compliant, making it suitable for North American government projects. For cybersecurity, it supports transport layer security, firmware signature, password protection, and port hardening.

Selection Guide & Purchasing Advice

Before ordering, verify your rack compatibility and power supply requirements. The BMEH584040 requires an internal power supply via the rack. If you need expanded memory, the module supports an optional 4 GB flash data storage card. BluePLC Industrial offers this module with fast shipping and full warranty.
