Schneider Electric BMEP581020 Modicon M580 Level 10 CPU 4-Rack 1024 DI/256 AI Programmable Logic Controller

The Schneider Electric BMEP581020 is a Modicon M580 Level 10 standalone processor module with built-in Ethernet, supporting up to 4 local racks, 1024 discrete and 256 analog local I/O channels, and 64 distributed Ethernet devices. It carries 4 MB of program memory, a 384 kB data memory, and a 775,000-hour MTBF rating, drawing 270 mA at 24 V DC.

Selection Notes

Select the BMEP581020 — the M580 Level 10 CPU — when a machine or line needs no more than 1024 discrete and 256 analog local I/O points across up to 4 racks and 64 distributed Ethernet devices; it is the entry processor in the M580 range rather than one sized for large distributed architectures. Its 4 MB program memory and 384 kB data memory cover mid-size control logic without stepping up to a higher-memory variant, and the 775,000-hour MTBF reflects the reliability class shared across the M580 processor family. Because I/O and distributed-device limits are fixed in the CPU itself, exceeding 1024 DI / 256 AI or 64 devices means moving to a higher-capacity processor rather than adding racks.
