• Model: Modicon M580 BMEH582040 (Redundant Pair Required)
• This processor is part of a hot standby system for seamless failover.
• It features a dedicated Ethernet HSBY port for synchronization between primary and standby CPUs.
• Delivers reliable performance at 40,000 Boolean instructions per millisecond.
• Integrated memory includes 8 MB for program and 768 kB for data storage.
• Expandable 4 GB flash storage is available for data and application backup.

System Architecture & Connectivity

• The redundant pair supports control of up to 8 local racks and 8 remote I/O racks.
• Manages communication with up to 61 Ethernet devices across the network.
• Integrated connectivity includes 3 standard Ethernet ports and 1 dedicated HSBY port.
• A USB mini-B port is provided for local service access and configuration.
• The system can manage 2 Ethernet communication modules for network expansion.

High Availability & Diagnostics

• Designed for zero-downtime operation in critical processes.
• Comprehensive status LEDs indicate processor state (RUN, Primary/Standby, A/B ID).
• LEDs provide clear diagnostics for Hot Standby link status and forced I/O.
• Automatic switchover occurs in case of a primary CPU failure, maintaining control.

• Rated for 3 gn vibration and 30 gn shock resistance in industrial environments.

Frequently Asked Questions (FAQ)

Q: Is the Modicon M580 BMEH582040 sold as a single unit or a pair?
A: It is sold as a single module. You must purchase two BMEH582040 processors to create a complete redundant hot standby system.

Q: What is the main purpose of a redundant processor like the BMEH582040?
A: The primary purpose is high availability. It prevents production stoppages by automatically switching control to a standby CPU if the primary fails, ensuring 24/7 operation for critical processes.

Q: How does the hot standby (HSBY) link work?
A: The dedicated Ethernet HSBY port continuously synchronizes data (program, variables, diagnostics) between the primary and standby BMEH582040 CPUs, enabling instantaneous, bumpless failover.

Q: Does this redundant CPU support remote I/O?
A> Yes, the Modicon M580 BMEH582040 system supports up to 8 remote I/O drops (X80 racks), allowing for distributed control architecture with redundancy.

Q: Is this TAA-compliant redundant processor in stock?
A: Yes, we usually have the BMEH582040 in stock to support urgent project timelines for critical infrastructure.

Q: What is the shipping and return policy for this item?
A: We ship within 5 business days via major carriers. A standard 30-day return policy applies to unused items in original packaging.

Q: Can I mix a BMEH582040 with a standard BMEP58xxx processor for redundancy?
A> No. A functional hot standby system requires an identical pair of BMEH582040 redundant processor modules.
