Featuring an instruction execution rate of 0.04 us for basic LD commands, the CPU minimizes internal scan overhead while processing high-density I\/O configurations up to 2,560 total points. High-speed backplane synchronization ensures stable bit-processing times and deterministic signal updates to local and expansion rack I\/O units. Memory handling allocates dedicated registers across 60K steps of program space and 160K words of data memory divided into structural banks, supporting multi-tasking execution profiles and advanced function block routines without degrading system latency.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Ordering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Omron CJ2M-CPU15 CPU Module\u003c\/li\u003e\n\u003cli\u003e1x End Cover (CJ1W-TER01 required for backplane termination)\u003c\/li\u003e\n\u003cli\u003e1x Instruction Manual Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRack Mounting:\u003c\/strong\u003e Secure the CPU module directly to the CJ-Series backplane rail interface adjacent to the power supply unit.
