The CPU pipeline executes basic LD instructions in 100 ns and complex MOV commands in 0.3 us, while maintaining a fixed system overhead time of 0.7 ms. Real-time tasks are managed using 256 subroutines and jumps, alongside 1 scheduled interrupt channel. Non-volatile project storage is sustained via CompactFlash cards, preserving program execution integrity without requiring constant backplane power.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Ordering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Omron CJ1M-CPU11 CPU Unit\u003c\/li\u003e\n\u003cli\u003e1x End Cover (CJ1W-TER01)\u003c\/li\u003e\n\u003cli\u003e1x Instruction documentation sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackplane Slot Installation:\u003c\/strong\u003e Mount the CJ1M-CPU11 directly onto the DIN rail adjacent to the CJ1 power supply unit.
