Schneider Electric BMEP584040 M580 Processor Module

Configured for programmable control execution and Ethernet-based I/O communication in the Modicon M580 platform, the Schneider Electric BMEP584040 (BMEP584040 processor module) provides processor resources for local and remote I/O processing, distributed equipment communication, and application task execution.

Hardware Specifications

Ethernet Communication and I/O Scaling

The BMEP584040 provides one Ethernet TCP/IP service connection and two Ethernet TCP/IP device-network connections. The processor supports RIO and DIO scanner services, up to 16 remote I/O stations, and up to 64 distributed devices.

Local processing capacity is specified as 4096 discrete I/O and 1024 analog I/O, with up to 144 application-specific channels. Supported application-specific functions include counter processing, SSI encoder interfaces, motion control, accurate time stamping, HART, and serial link functions.

The processor provides 16 MB of program RAM, 2048 kB of data RAM, 10 kB of system memory, and 4 GB of expandable flash storage for data.

Frequently Asked Questions

Q: How is the BMEP584040 powered within the M580 system?
A: The processor receives its internal power supply through the rack. The specified current consumption is 295 mA at 24 VDC.

Q: How many remote I/O stations can the processor handle?
A: The specified capacity is 16 remote I/O stations, with up to 2 racks per remote drop.

Q: What physical network connections are integrated into the processor?
A: The module provides 1 Ethernet TCP/IP service port, 2 Ethernet TCP/IP device-network ports, and 1 USB Type Mini-B connection.

Field Installation Guidelines

Install the processor in the designated Modicon M580 rack position and verify correct mechanical engagement with the rack backplane before energizing the system.

Route Ethernet communication cables separately from high-current power conductors and other sources of electrical interference where practical. Maintain the cable shielding and grounding arrangement specified by the M580 installation documentation.

Verify that the cabinet ambient temperature remains within 0 to 60 deg C during operation. The module has an IP20 enclosure rating and should therefore be installed inside an enclosure providing the required environmental protection.

Check rack power distribution, module seating, Ethernet connections, and status LEDs before commissioning. Do not remove or replace the processor while energized unless the applicable M580 hardware documentation explicitly permits the procedure for the installed rack configuration.
