Full specifications and sourcing options are below.","salesMarkdown":"## Overview The BMEH586040 is a Schneider Modicon M580-series PLC expansion module, order code BMEH586040, carrying 64 MB of program and data RAM plus 4 GB of expandable flash storage. It integrates six Ethernet communication ports — one service port, two device network ports, one HSBY port — and draws its supply from the rack backplane. Rated IP20 for in-cabinet mounting, it carries CE, UL, CSA, RCM, EAC and Merchant Navy certifications and is compliant with IEC 61131-2, IEC 61010-2-201, UL 61010-2-201, and EN/IEC 61850-3. The BMEH586040 functions as a high-capacity expansion processor within a Modicon M580 rack, handling program execution, data logging, and hot-standby synchronisation. Its 64 MB of integrated RAM for program and data supports large control applications with extensive tag databases and recipe management, while the 4 GB expandable flash provides room for data storage, firmware archives, and web-server content. The six Ethernet ports enable segmented network topologies: a dedicated service port for programming and HMI, two device network ports for plant-wide I/O and drive communication, and an HSBY port for redundant processor links. On-board diagnostics are delivered through a comprehensive LED array — RUN, ERR, I/O fault, DL, BACKUP, ETH MS/NS, REMOTE RUN, A/B processor ID, PRIM/STBY, FORCED IO, and Hsby Diag — giving immediate visual status of processor health, network connectivity, and redundancy state. The module is Achilles certified for cybersecurity, with IPSec, SNMP logging, Syslog, TLS, audit trail, embedded firewall, firmware signature, password protection, port hardening, and secure HTTPS communication. ## Applications This expansion module is deployed in process and hybrid automation applications where high availability and cybersecurity are critical — oil and gas pipelines, power substations, water treatment plants, and marine systems. Its EN/IEC 61850-3 compliance suits electrical substation automation, while the Merchant Navy certification covers shipboard control systems. The module supports application-specific I/O including counter, SSI encoder, serial link, HART, accurate time stamping, and motion control, making it suitable for complex skids and rotating machinery. The BMEH586040 is an active, in-production module within Schneider's Modicon M580 range. It carries CE, UL, CSA, RCM, EAC, Merchant Navy certifications.","metaTitle":"Schneider BMEH586040 Modicon M580 PLC Expansion Module, 64 MB","metaDescription":"Schneider Modicon M580 BMEH586040 PLC expansion module: 64 MB program/data RAM, 4 GB flash, 6 Ethernet ports, IP20, CE/UL/CSA, 30 gn shock.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Checks":"Process control","Supply":"Internal power supply via rack","Marking":"CE","Category":"US1PC3418161","Standards":"IEC 61131-2 IEC 61010-2-201 UL 61010-2-201 CSA C22.2 No 61010-2-201 IACS E10 EN/IEC 61000-6-5, interface type 1 and type 2 EN/IEC 61850-3, location G","Directives":"2014/35/EU - low voltage directive 2014/30/EU - electromagnetic compatibility","Status LED":"1 LED (Green) processor running (RUN) 1 LED (Red) processor or system fault (ERR) 1 LED (Red) I/O module fault (I/O) 1 LED (Green) download in progress (DL) 1 LED (Red) memory card or CPU flash fault (BACKUP) 1 LED (green/red) ETH MS (Ethernet port configuration status) 1 LED (green/red) Eth NS (Ethernet network status) 1 LED (Green) peer processor running (REMOTE RUN) 1 LED (Green) processor ID set to A (A) 1 LED (Green) processor ID set to B (B) 1 LED (Green) processor acting as Primary (PRIM) 1 LED (Green) processor acting as Standby (STBY) 1 LED (Green) I/O values overrided by user (FORCED IO) 1 LED (Green) Hot standby link status (Hsby Diag)","Cybersecurity":"Achilles certified DoS prevention IPSec SNMP logging Syslog protocol support Transport layer security Audit trail Embedded firewall Firmware signature Password protection Port hardening Secure communication (HTTPS) Security log","Number of racks":"1","lifecycle_stage":"current","Control channels":"Programmable loops","MTBF reliability":"650000 H","Range of Product":"Modicon M580","Shock resistance":"30 gn","Relative humidity":"5...95 % 131 °F (55 °C) without condensation","Memory description":"Expandable flash, 4 GB data storage Integrated RAM, 10 kB system memory Integrated RAM, 64 MB program and data Integrated RAM, 4096 kB HSBY data","Operating altitude":"0...6561.68 ft (0...2000 m) 2000...5000 m with derating factor","Current consumption":"365 mA 24 V DC","Vibration resistance":"3 gn","Application structure":"1 cyclic/periodic master task 1 periodic fast task","Communication Service":"DIO scanner RIO scanner","Compliance/Compliance":"TAA BAA via COTS","Nbr. of units in pkg.":"1","IP Degree of Protection":"IP20","Application specific I/O":"Counter SSI encoder Serial link HART Accurate time stamping Motion control","Product or Component Type":"Redundant processor module","Integrated connection type":"1 Ethernet TCP/IP service port 2 Ethernet TCP/IP device network USB type mini B 1 Ethernet HSBY port","Environmental characteristic":"Hazardous location class I division 2","Number of remote I/O station":"31 - 2 X80 and Quantum drops","Number of instructions per ms":"40 Kinst/ms 65 % Boolean + 35 % fixed arithmetic 50 Kinst/ms 100 % Boolean","Number of distributed equipment":"64","Ambient Air Temperature for Storage":"-40...185 °F (-40...85 °C)","Ambient Air Temperature for Operation":"32...140 °F (0...60 °C)","Communication module processor capacity":"6 Ethernet communication module 16 AS-Interface module"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6,757.67","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/de410ed5e4039455820c825016a9ab85.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/BMEH586040/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/BMEH586040","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/BMEH586040 when reusing this data.
