Product Overview
The Omron NX102-1200 is a modular NX1-series machine automation controller CPU, 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.
The CPU ships with 5 MB of program memory and 33.5 MB of variables (1.5 MB retained, 32 MB non-retained). Motion control covers 12 real axes: 8 synchronous EtherCAT servo axes plus 4 single-axis position control axes. Primary task cycle is 1 ms.
Two 100BASE-TX Ethernet sockets run EtherNet/IP and OPC-UA, plus a dedicated EtherCAT master port. Up to 32 local NX I/O units attach on the right, and 64 remote EtherCAT nodes are reachable through a coupler (up to 400 NX units end-to-end). Serial or analog expansion goes on an NX1W option board fitted to an NX1 I/O unit, not on this CPU. For SQL database connectivity, pick the NX102-9020. Programming is in Sysmac Studio.
Key Features
- NX102 modular CPU, 5 MB program / 33.5 MB variables (1.5 MB retained, 32 MB non-retained), 1 ms primary task cycle
- 8 synchronous EtherCAT servo axes + 4 single-axis position control axes (12 real axes max)
- Built-in EtherCAT master + 2 EtherNet/IP ports with OPC-UA server, 64 remote I/O nodes
- 32 local NX I/O units, SD memory card slot, battery-less operation, sequence + motion + position control
- SKU: NX102-1200
- Series: Omron NX102-series modular machine automation controller
- I/O: 32 I/O
Best-Fit Applications
- Multi-axis packaging line where 8 EtherCAT servos coordinate cutting and sealing stations with 1 ms deterministic cycle time
- Converting machine builder who needs an OPC-UA server to publish live machine data to a higher-level MES without an extra gateway
- Spare replacement on a retrofit where the old NJ-series CPU is being upgraded to NX102 to add EtherCAT ring topology redundancy
Buying Checklist
- Pick the NX102-1200 for a modular NX102 CPU with 8 EtherCAT servo axes and OPC-UA without SQL database connection.
- Pick the NX102-1100 instead when 4 motion axes and a smaller scope are enough and the budget is tighter.
- Pick the NX102-1220 instead when the line needs direct SQL database and MQTT connection on the controller itself.

FAQ for NX102-1200
What is the Omron NX102-1200 used for?
It is a modular NX1-series CPU for mid-size machines with 8 or fewer servo axes. Sequence, motion, position control, and OPC-UA run on a single 1 ms task, with EtherCAT and EtherNet/IP in one compact body.
Does the NX102-1200 have SQL database connection?
No. This model ships with OPC-UA but no SQL client. For direct SQL database connection (Microsoft SQL, Oracle, MySQL, PostgreSQL, etc.), pick the NX102-1220 sibling.
NX102-1200 vs NX102-1100 - what is the difference?
The 1200 supports 8 synchronous servo axes plus 4 PTP axes (12 total). The 1100 supports 4 synchronous servo axes plus 4 PTP axes (8 total). Memory and I/O limits are identical between the two.
How many local NX I/O units can attach to the NX102-1200?
Up to 32 NX units local on the right side of the CPU. Over EtherCAT, up to 64 remote nodes with another 400 NX units accessible through an NX-ECC coupler.
