Schneider Electric BMEP582020 Modicon M580 Level 20 CPU 4-Rack 2048 DI/512 AI Programmable Logic Controller

The Schneider Electric BMEP582020 is a Modicon M580 Level 20 standalone processor module with built-in Ethernet, supporting up to 4 local racks, 2048 discrete and 512 analog local I/O channels, and 128 distributed Ethernet devices. It carries 8 MB of program memory, a 768 kB data memory, and a 775,000-hour MTBF rating, drawing 270 mA at 24 V DC.

Selection Notes

Select the BMEP582020 — the M580 Level 20 CPU — over the entry-level processor when an architecture needs more than 64 distributed Ethernet devices or more than 1024 discrete / 256 analog local I/O points; it doubles both local I/O capacity (2048 DI / 512 AI) and the distributed-device ceiling (128) of the entry CPU. Its 8 MB program memory and 768 kB data memory give roughly twice the application headroom, which matters for projects with more function blocks or larger data structures than the entry-level CPU can hold. Local rack count stays capped at 4, so an architecture needing remote I/O racks beyond that should use a processor built for remote-drop expansion instead.
