Schneider Electric BMEH584040 Modicon M580 Redundant Processor Module

The Schneider Electric BMEH584040, also cataloged as the BMEH584040 redundant processor module, executes processor control, Ethernet communication, and hot standby functions within Modicon M580 architectures. It provides integrated RAM for program and data storage, Ethernet TCP/IP interfaces, USB connectivity, and a dedicated HSBY port.

Hardware Specifications

Modicon M580 Ethernet and Redundancy Architecture

The BMEH584040 integrates Ethernet TCP/IP interfaces for service and device network communication. A dedicated Ethernet HSBY port supports communication between redundant processor configurations.

The processor supports up to 16 remote I/O stations using X80 and Quantum drops. It also supports RIO and DIO scanner services for remote and distributed equipment communication.

The specified communication capacity includes up to 16 Ethernet communication modules and 8 AS-Interface modules. Network functions include IPSec, TLS, HTTPS, SNMP logging, Syslog, audit trail, embedded firewall, firmware signature validation, port hardening, and password protection.

Frequently Asked Questions

Q: Does the BMEH584040 require a separate external power supply connection?
A: No. The supplied specification identifies an internal power supply through the rack, with a specified current consumption of 360 mA at 24 V DC.

Q: What memory resources are integrated into the processor?
A: The processor provides 16 MB for program memory, 2,048 kB for data, 10 kB for system memory, and expandable 4 GB flash storage for data.

Q: What Ethernet interfaces are available on the module?
A: The module provides one Ethernet TCP/IP service port, two Ethernet TCP/IP device network ports, and one Ethernet HSBY port.

Field Installation Guidelines

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

Confirm rack power compatibility and verify that the available rack supply supports the processor current requirement.

Route Ethernet communication cables separately from high-current power conductors, motor cables, and switching circuits where practical.

Maintain appropriate cable shielding and bonding practices according to the installed network architecture and site EMC requirements.

Use the dedicated HSBY connection for the redundant processor link and verify processor A/B identification before commissioning.

Check RUN, ERR, I/O, Ethernet, REMOTE RUN, PRIM, STBY, and HSBY diagnostic indicators during startup.

Verify firmware and application compatibility before downloading or replacing processor firmware.

Do not remove or insert the processor unless the applicable Modicon M580 installation procedure confirms that the operation is permitted for the specific system configuration.
