Schneider Electric BMEP582040S Modicon M580 Safety Processor

Configured for safety control execution and Ethernet-based remote I/O communication in the Modicon M580 platform, the Schneider Electric BMEP582040S (BMEP582040S Safety Processor) provides processor, safety memory, Ethernet service, and remote I/O network functions through the M580 rack.

Hardware Specifications

M580 Ethernet and I/O Architecture

The BMEP582040S provides one Ethernet TCP/IP service port and two Ethernet TCP/IP device network ports. The two device ports support the remote I/O network for M580 remote drops. The processor supports up to 8 remote I/O stations, 64 distributed devices, and 16 CIP Safety I/O devices.

Local processing capacity includes up to 2048 discrete I/O and 512 analog I/O. Supported application-specific functions include counter processing, motion control, SSI encoder handling, accurate time stamping, serial link functions, and HART communication.

The processor includes separate process and safety memory areas. Memory consists of 8 MB program RAM, 768 kB process data RAM, 10 kB system memory, 2 MB safety program memory, 512 kB safety data memory, and 4 GB expandable flash storage.

Frequently Asked Questions

Q: How is the BMEP582040S powered in the M580 rack?
A: The processor receives its operating power from the rack internal power supply. The specified current consumption is 295 mA at 24 VDC.

Q: How many Ethernet interfaces are provided?
A: The module has one Ethernet TCP/IP service port and two Ethernet TCP/IP device network ports. The device network ports support the remote I/O network.

Q: What are the installation positions for the processor?
A: The CPU is installed in the rack slots marked 00 and 01. Two screws on the top of the CPU secure the module to the rack.

Field Installation Guidelines

Install the BMEP582040S in the designated M580 rack CPU positions and secure the module using the specified top mounting screws. Verify that the rack backplane is correctly installed before applying power.

Connect the Ethernet service port and device network ports according to the M580 network architecture. Keep Ethernet communication wiring separated from high-voltage power conductors and high-current switching circuits where practical.

For shielded communication cables, terminate the shield according to the applicable M580 installation and EMC requirements. Avoid routing communication cables alongside motor power or switching cables for extended distances.

The module is IP20 rated and conformal coated. The enclosure and cabinet should therefore provide the required protection against direct contact, conductive contamination, condensation, and mechanical damage.

Before commissioning, verify the RUN, ERR, I/O, DL, BACKUP, ETH MS, ETH NS, SRUN, SMOD, and FORCED IO indicators. Confirm the processor configuration and safety application using EcoStruxure Control Expert before placing the controller into service.
