The real-time clock and battery backup keep the data alive across power cycles, so the machine doesn't lose accumulated counts or shift register states on a brownout. ## Fieldbus mix for a distributed architecture Three communication interfaces on one CPU — Ethernet, EtherCAT, and EtherNet/IP — let this controller talk to servo drives on the high-speed motion bus while the HMI and upstream SCADA sit on the IT-friendly EtherNet/IP segment. The 100 Mbps baud rate on the EtherCAT port keeps the cycle time under 1 ms for a 16-axis coordinated move, which is the usual bottleneck on mixed-protocol machines. ## Mounting and wiring that match the panel layout DIN rail or panel mount — the same base unit fits either a standard 35 mm rail or a backplate with four screws, so the panel builder can lay out the cabinet without a dedicated sub-panel.","metaTitle":"Omron NX1021120 NX1 PLC, 5 MB Program, 33.5 MB Data","metaDescription":"Omron NX1021120 NX1 series PLC with 5 MB program capacity, 33.5 MB data memory, EtherCAT/EtherNet/IP, 24 VDC.
