Schneider Electric BMEP584040C Modicon M580 Processor Module

The Schneider Electric Modicon M580 BMEP584040C, also cataloged as the BMEP584040C Processor Module, operates as a standalone PAC CPU for processing control logic, Ethernet communications, local I/O scanning, and distributed device data within the Modicon M580 platform. Its integrated Ethernet interfaces support service, device-network, and DIO communication functions.

Hardware Specifications

Ethernet Backplane and I/O Processing

The BMEP584040C uses the Modicon M580 Ethernet backplane architecture for controller-to-I/O and network data exchange. The CPU provides one service Ethernet connection and two device-network Ethernet connections, allowing separate physical interfaces for engineering/service access and device communications.

The processor supports RIO and DIO scanning and can manage up to 16 remote I/O stations and 64 distributed devices. Local application capacity includes discrete, analog, counter, SSI encoder, motion-control, HART, serial-link, and time-stamping functions.

The conformal-coated construction is identified by the C suffix. The coating is intended for operation in environments subject to humidity, corrosive gases, and airborne chemical contaminants.

Cybersecurity and Firmware Functions

The controller includes embedded cybersecurity functions including IP address and MAC address filtering, denial-of-service prevention, IPSec, SNMP logging, Syslog, TLS, audit trail, embedded firewall functions, firmware signature verification, password protection, port hardening, HTTPS, and security logging.

The supplied data identifies Achilles certification and support for secure communication functions. Firmware and security configuration should be matched to the installed Modicon M580 hardware and engineering software versions before commissioning.

Frequently Asked Questions

Q: Can the BMEP584040C operate in a Hot Standby configuration?
A: The supplied specifications identify the BMEP584040C as a standalone CPU with non-Hot Standby configuration.

Q: What is the specified controller current consumption?
A: The supplied data specifies 295 mA at 24 VDC. It also lists approximately 9.5 W power consumption.

Q: Can the CPU communicate directly with Ethernet field devices?
A: Yes. The CPU provides two Ethernet TCP/IP device-network ports and supports protocols including Modbus TCP and EtherNet/IP.

Field Installation Guidelines

• Install the CPU on a compatible BMEXBPxxxx Modicon M580 backplane and verify mechanical engagement before energizing the rack.
• Confirm that the backplane, power supply, CPU, and connected I/O modules are compatible with the intended M580 architecture.
• Maintain physical separation between Ethernet communication cables and high-current or high-voltage power conductors where required by the installation design.
• Terminate cable shields and protective earth connections according to the site grounding design and Schneider Electric installation requirements.
• Verify the 24 VDC supply polarity and allowable supply characteristics before connecting the CPU.
• Use the designated service and device-network Ethernet ports according to the network topology. Avoid connecting redundant or isolated networks together unintentionally.
• Inspect the conformal-coated module for mechanical damage or contamination before installation. Do not remove or abrade the protective coating.
• Before commissioning, verify firmware compatibility, cybersecurity settings, IP addressing, and the configuration of RIO/DIO scanners against the actual rack and field-device topology.
