Internal cycle execution for basic logic instructions runs at 0.10 microseconds, minimizing overall scan times. The integrated Ethernet port operates as a dedicated network interface directly accessing the memory address space (32K words DM) via FINS (Factory Interface Network Service) protocol commands. Network data processing is decoupled from main program scan cycles to maintain fixed execution timing while handling socket services, IP routing, and peer-to-peer messaging.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Ordering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Omron CJ1M-CPU11-ETN CPU Unit\u003c\/li\u003e\n\u003cli\u003e1x End Cover (CJ1W-TER01 required for backplane termination)\u003c\/li\u003e\n\u003cli\u003e1x Quick Reference Manual Document\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Configuration:\u003c\/strong\u003e Mount the unit directly onto a standard 35 mm DIN rail.
