The NX1021100: The Omron NX102-1100 is a Sysmac NX1-series programmable logic controller intended for mid-range machine control where motion, EtherCAT servo axes, and plant-level Ethernet share one CPU. It runs from a 24 V DC supply with an operating window of 20 V to 24 V, so the panel PSU must hold regulation above 20 V under load — drop below that and the CPU stops executing. Program capacity is 5 MB and data memory is 33.5 MB, which is the envelope you budget against for ladder + structured-text logic, recipes, and retained variables. Battery backup is present along with a real-time clock, so retentive tags and the wall-clock survive a power cycle without external UPS work.
Network and motion footprint
Three industrial Ethernet protocols ride out of the same port block — Ethernet, EtherCAT, and EtherNet/IP — with a 100 Mbps maximum baud rate, so it can act as both machine controller (EtherCAT for servos/inverters) and plant-side node (EtherNet/IP scanner/adapter) without an extra gateway. Programming is via Ladder Diagram (LD) and Structured Text (ST) in the Sysmac Studio toolchain; pick ST for motion math and recipe data structures, LD for bit-level I/O sequencing.
Panel-side mounting and I/O expansion
Mounting is rated for both DIN-rail and panel-mount installations, and the push-in terminal style means ferruled or solid conductors land without a screwdriver — strip and seat, done. Expansion is supported, so the local NX I/O bus can grow to 32 modules on the right of the CPU for digital, analog, and safety slices as the machine scales.
