Product Overview
The Omron NX102-1100 is the Sysmac NX1 modular CPU unit, manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
It runs on 24 VDC, holds 5 MB of program memory and 33.5 MB of variables memory, and combines logic, motion, position, and OPC UA in one controller. The built-in EtherCAT master drives 4 synchronous servo axes and 4 single-axis PTP axes (15 total with virtual) with a 1 ms primary task cycle and 3.3 ns LD execution.
Two RJ45 Ethernet ports run EtherNet/IP (64 tag-data-link nodes) and standard TCP/IP. OPC UA is built in for SCADA / MES connectivity. Up to 32 NX expansion units stack on the local NX I/O bus and up to 64 EtherCAT slaves on remote nodes. Two option-board slots accept NX1W-CIF01 / CIF11 / CIF12 for serial. The lower-axis sibling is NX102-1000 (2 servo). The 8-servo step-up is NX102-1200. Older NJ1 controller is NJ101-1000.
Key Features
- Sysmac NX1 modular CPU with 5 MB program memory and 33.5 MB variables memory (1.5 MB retained / 32 MB volatile)
- Built-in EtherCAT master with 4 synchronous servo axes + 4 single-axis position control axes (15 total including virtual) and 1 ms primary task cycle
- Built-in EtherNet/IP scanner (64 connections), Ethernet TCP/IP, and OPC UA server for SCADA / MES integration
- Up to 32 NX-series expansion units on the local bus and 64 EtherCAT remote nodes; 2 option board slots for serial; 24 VDC supply; 470 g
- SKU: NX102-1100
- Series: Sysmac NX1 modular CPU (NX102 CPU family) on NX I/O Bus
- I/O: 32 I/O
Best-Fit Applications
- Four-axis pick-and-place cell where the NX102-1100 drives four 1S-series servos over EtherCAT and reads an NB5Q HMI on EtherNet/IP
- Synchronized cut-to-length line where the NX102-1100 positions a flying shear via electronic cam against a master encoder input
- Spare replacement on a packing machine where the original NX102-1100 was lost and Sysmac Studio has the project backup on the SD card
Buying Checklist
- Pick the NX102-1100 when the application needs 4 synchronous servo axes + 4 PTP axes with built-in OPC UA on a 66 mm wide modular CPU.
- Pick the NX102-1000 instead when 2 servo axes + 4 PTP axes is enough and no OPC UA is required (the lower-cost variant).
- Pick the NX102-1200 instead when 8 synchronous servo axes + 4 PTP axes is required on the same 5 MB / 33.5 MB body.

FAQ for NX102-1100
NX102-1100 vs NX102-1200 - what is the difference?
Both are NX102 modular CPUs with 5 MB program / 33.5 MB variables memory. The 1100 has 4 synchronous servo axes + 4 PTP axes (15 total). The 1200 has 8 synchronous servo axes + 4 PTP axes (15 total). Both share the same 66 x 100 x 100 mm body, OPC UA server, and EtherNet/IP 64-connection scanner. Pick the 1100 for 4 servo; pick the 1200 for 8 servo.
Does the NX102-1100 need a separate EtherCAT Coupler?
No. The NX102-1100 is a modular CPU with built-in EtherCAT master. NX expansion units (digital I/O, analog, temperature, encoder) stack on the right side of the CPU and communicate over the internal NX bus. Remote EtherCAT slaves (G5 servo drives, MX2 inverter, NX-ECC201 slave terminals) hang off the EtherCAT port on the bottom.
Which software version is required to program the NX102-1100?
Sysmac Studio version 1.22 or higher. Older revisions will not recognize the CPU or expose the OPC UA server. The project lives in the controller or on a 5 mm HMC-SD291 SD card in the SD slot.
