Schneider Electric BMEH586040C Modicon M580 Redundant Processor Module

Configured for redundant PAC control in the Modicon M580 platform, the Schneider Electric BMEH586040C (BMEH586040C Redundant Processor Module) provides processor-level hot standby execution with Ethernet communication and rack-based power.

Hardware Specifications

Modicon M580 Redundant Processor and Ethernet Architecture

The BMEH586040C implements Level 6 hot standby processing within a Modicon M580 controller architecture. The module provides dedicated Ethernet interfaces for service, device networking, and processor redundancy.

The processor supports RIO and DIO scanner services and can manage up to 31 remote I/O stations. The supplied specifications also define support for application-specific functions including serial communication, precise time stamping, SSI encoders, motion control, HART, and counters.

The processor includes separate status indicators for RUN, ERR, I/O, download, backup, Ethernet network status, remote processor operation, processor identity, primary or standby state, forced I/O, and hot standby diagnostics.

The conformal-coated circuit board supports specified gas, dust, sand, salt, mold, and fungal-spore resistance classifications. Environmental compliance includes ISA S71.04 Gas Resistant Class Gx and IEC 60721-3-3 classifications.

Frequently Asked Questions

Q: Does the BMEH586040C obtain its operating power from an external 24 VDC supply?

A: No. The supplied specifications identify internal rack power as the processor power source, with a consumption of 365 mA at 24 VDC.

Q: Which communication interfaces are provided on the processor?

A: The module provides Ethernet TCP/IP service and device-network interfaces, a dedicated Ethernet hot standby interface, and a Mini-B USB interface.

Q: What environmental operating temperature is specified for this processor?

A: The specified operating range is -25 to 60 deg C, while the storage range is -40 to 85 deg C.

Field Installation Guidelines

Install the processor in the specified Modicon M580 rack position and verify mechanical engagement before energizing the rack.

Use the rack power architecture specified for the M580 system and confirm the available current capacity against the processor load.

Route Ethernet, USB, and other communication cables separately from high-current switching conductors where practical to reduce electromagnetic coupling.

Maintain appropriate cable shielding and bonding practices according to the M580 installation documentation and the applicable EMC requirements.

For redundant processor installations, verify processor identification, Primary/Standby status, and the hot standby link before placing the control system into service.

Check the RUN, ERR, I/O, ETH MS, ETH NS, PRIM, STBY, and Hsby Diag indicators during commissioning to confirm processor and network states.

Do not remove or insert the processor unless the applicable M580 hot-swap and energized-rack procedures explicitly permit the operation.

For installations in classified environments, verify that the complete system configuration satisfies the applicable ATEX or IECEx installation requirements.
