SCHNEIDER BMEP585040 – Ethernet CPU Module for Modicon M580 (X80) Control Systems

The SCHNEIDER ELECTRIC BMEP585040 is a Modicon M580 ePAC CPU module designed for high‑reliability machine and process automation. You might notice the part looks similar in form to M340 hardware, but this is an M580-series processor that leverages the shared X80 I/O platform. From my experience, it’s a practical choice when you’re modernizing from M340 to M580: you keep X80 I/O, gain native Ethernet performance, and simplify diagnostics with the embedded web server.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days coverage
• Lead time: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full balance before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Native Ethernet controller – Typically includes dual RJ45 ports for Modbus TCP and EtherNet/IP communications with embedded web diagnostics.
• X80 I/O ecosystem – Works with Modicon X80 I/O locally or remotely, which makes M340-to-M580 migrations straightforward in many cases.
• Robust real-time control – Deterministic task scheduling via EcoStruxure Control Expert (Unity Pro) for mid-to-large applications.
• Service/maintenance friendly – USB service port and SD card support for program backup, firmware updates, and quick swap-outs.
• Cybersecurity features – User roles, password protection, and locked configuration workflows to help reduce unauthorized changes.
• Scalable networking – Can be expanded with additional Ethernet/fieldbus modules when the architecture grows (e.g., BMENOC series).
• Industrial temperature range – Designed for cabinet environments commonly specified in infrastructure, water, energy, and discrete manufacturing.

Technical Specifications

Note: BMEP585040 is part of the Modicon M580 family. If you are currently operating M340, migration is typically seamless because both platforms use X80 I/O, but it’s not an M340 CPU module.

Application Fields

• Water and wastewater treatment (clarifiers, filtration skids, pump stations)
• Food & beverage and packaging lines needing deterministic motion and I/O density
• Power and utility substations for auxiliaries and plant balance systems
• Oil & gas terminals and pipelines with Modbus TCP telemetry
• Material handling, intralogistics, and AS/RS where high availability is valued
• Hybrid and process manufacturing lines consolidating multiple PLC islands into one Ethernet architecture

Advantages & Value

• Lifecycle confidence – The M580 platform is actively supported, which typically reduces obsolescence risk for multi-year projects.
• Migration-friendly – Reuse X80 I/O and much of your existing wiring; engineering reuse through EcoStruxure Control Expert cuts commissioning time.
• Lower total cost – Fewer gateways thanks to native Ethernet, plus web diagnostics that shorten troubleshooting in many cases.
• Openness – Out-of-the-box Modbus TCP and EtherNet/IP let you integrate drives, HMIs, and third-party devices without vendor lock-in.
• Technical backing – Strong global ecosystem, spare parts availability, and firmware roadmap that keeps features current.

Installation & Maintenance

• Cabinet & backplane – Install on a BMEXBP backplane mounted to a grounded DIN rail or panel. Leave ventilation clearance above and below (at least 50 mm is common practice).
• Power – Use a BMXCPS power supply sized for total backplane current. Check backplane consumption of each module; the CPU typically draws 5 VDC via backplane.
• Wiring – Use industrial Ethernet cabling (Cat5e/Cat6) with shielded RJ45 connectors in noisy environments. Keep network and power cables separated.
• Grounding & EMC – Bond cabinet ground and observe shield termination at a single point to minimize noise coupling.
• Firmware & backups – Keep CPU firmware aligned with engineering tool versions. Store application backups on the SD card and in your CM system.
• Routine care – Quarterly dust removal with dry air, inspect connectors and locking tabs, verify log timestamps, and review diagnostic web pages for alarms.
• Safety – De-energize before insertion/removal. Observe ESD handling; the front port covers should remain closed in normal operation.

Quality & Certifications

• Conformity: CE marked; cULus listed (typical for M580 platform); RoHS and REACH compliant
• Manufacturing quality: Produced under ISO 9001 quality systems
• Warranty: 365 days

Related & Supporting Components

• BMEXBP•• backplanes – Choose slot count based on I/O density and spare capacity (e.g., BMEXBP0400, BMEXBP0800).
• BMXCPS power supplies – 24 VDC and 100–240 VAC variants sized to the rack load.
• BMENOC0311 – Optional Ethernet communication module if you need additional ports or network segmentation.
• X80 I/O modules – Discrete, analog, temperature, and specialty I/O to match field signals.
