The 160K words data memory (DM: 32K words, EM: 32K words × 4 banks) supports large data tables and recipe storage, while the 30000-step program capacity accommodates mid-sized control applications. Built-in EtherNet/IP at 100 Mbps enables high-speed plant-floor networking and integration with other EtherNet/IP devices, and the 1.4 µs scan time provides fast logic execution for time-critical processes. The RS-232C and USB interfaces allow direct connection to programming tools and legacy serial devices, and the optional expansion slot supports additional communication modules. ## Lifecycle The CJ2M-CPU34 has been discontinued by Omron.","metaTitle":"Omron CJ2M-CPU34 PLC CPU, 2560 I/O, Ethernet/IP, 100 Mbps","metaDescription":"Omron CJ2M-CPU34 PLC CPU, 2560 I/O points, 160K words data memory, 30000 steps program capacity, Ethernet/IP, USB, RS-232C, 5 V DC, DIN rail, IP20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Series":"CJ2M","Weight":"0.419 lb (190.06 g)","Package":"Box","Features":"Battery Backup","Software":"CX-One","Expandable":"40 Modules (3 Racks) Max","Memory Size":"160K Words","Display Type":"No Display","Mounting Type":"DIN Rail","Communications":"Ethernet, USB, Option Cards Available","Approval Agency":"CE, cULus, Lloyd, NK","lifecycle_stage":"mature","Operating Temperature":"0°C ~ 55°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$532.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/CJ2M-CPU34","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/CJ2M-CPU34 when reusing this data.
