The embedded EtherNet\/IP controller processes implicit I\/O data links and explicit message communications without degrading central logic scan execution. Operating over standard IEEE 802.3 Ethernet transport layer, the integrated EtherNet\/IP port supports cyclic data tags and CIP safety\/data routing across factory networks. Backplane data exchange latency between the CPU and expansion units remains optimized via dedicated DMA bus transactions, maintaining deterministic scan timing when managing up to 40 local or expansion I\/O modules across 3 expansion racks.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Ordering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Omron CJ2M-CPU35 CPU Unit\u003c\/li\u003e\n\u003cli\u003e1x CJ1W-TER01 Backplane End Cover\u003c\/li\u003e\n\u003cli\u003e1x Instruction Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN Rail Mounting:\u003c\/strong\u003e Hook the top CPU notch onto the DIN rail and snap the bottom lock mechanism into place.
