Schneider Electric BMEP582020 Modicon M580 Processor Module

Configured for programmable control, local I/O processing, and Ethernet device communication in the Modicon M580 platform, the Schneider Electric BMEP582020 (BMEP582020 Processor Module) provides processor execution through the rack power and backplane interface. It supports up to 4 racks, 2048 discrete local I/O, 512 analog local I/O, and 128 distributed devices.

Hardware Specifications

Ethernet Networking and I/O Processing

The BMEP582020 provides two Ethernet TCP/IP ports for the device network and one Ethernet TCP/IP service port. The processor supports up to 128 distributed devices and provides DIO scanner functionality. Local processing capacity is specified as 2048 discrete I/O and 512 analog I/O across a maximum of 4 racks.

The processor also supports application-specific functions including HART, SSI encoder, motion control, serial link, accurate time stamping, and counter functions. Ethernet connectivity is separated into service, device network, and dedicated HSBY functions according to the M580 hardware configuration.

Frequently Asked Questions

Q: How much local I/O can the processor handle?
A: The BMEP582020 supports up to 2048 discrete local I/O and 512 analog local I/O across a maximum of 4 racks.

Q: Can the processor use external flash storage?
A: The processor provides integrated RAM for program, data, and system functions and supports expandable flash storage up to 4 GB for data storage.

Field Installation Guidelines

Install the processor in the specified Modicon M580 rack position and ensure that the rack power and backplane connections are fully seated before energizing the system.

Route Ethernet communication cables separately from high-current power conductors and switching circuits where practical. Maintain appropriate cable shielding and grounding practices for the selected network installation.

Verify the Ethernet service and device network connections against the configured M580 architecture before commissioning. Confirm processor status indicators, including RUN, ERR, I/O, DL, BACKUP, and Ethernet status LEDs, during startup and fault diagnosis.

Observe the specified ambient temperature, humidity, altitude, vibration, shock, and IP20 environmental limits. Installation in a hazardous location must follow the applicable site classification, enclosure, wiring, and certification requirements.
