The Omron NX102-9000, also cataloged as the NX102-9000 Modular CPU, operates as a dedicated hardware component for multi-axis position control, sequence execution, and OPC-UA data bridging within Sysmac Sysmac NX1 platform architectures.

System Model Nomenclature

The hardware part number structure designates core processing parameters:

• NX102: Compact Sysmac CPU controller hardware platform with integrated EtherCAT and EtherNet/IP bus interfaces.
• 9000: Standard database/OPC-UA network integration feature set without safety control extensions.

Physical & Electrical Performance Parameters

Deterministic Network Execution & I/O Density Scaling

The CPU core coordinates high-speed EtherCAT motion axes alongside EtherNet/IP deterministic networks, maintaining microsecond-level synchronization across distributed servo drives. Backplane bus communication velocity allows up to 32 local NX I/O modules to update in real time while maintaining firmware flash compatibility and program execution consistency under dense I/O density scaling profiles.

Package & Component Listing

• 1 x Omron NX102-9000 Sysmac NX1 Modular CPU Unit
• 1 x End cover unit (NX-END02)
• 1 x Power supply terminal connector block
• 1 x Installation guide sheet

Field Installation & Enclosure Guidelines

• Mount the controller vertically onto a standard 35 mm DIN rail inside an IP54-rated industrial control enclosure.
• Ensure a minimum vertical clearance of 30 mm above and below the housing for proper convection cooling.
• Terminate the 24 VDC power supply wiring using 16 AWG conductors with crimped ferrules into the removable terminal block.
• Connect the protective earth (PE) terminal directly to the enclosure backplate ground copper bus.
• Snap local NX series I/O modules sequentially onto the right side of the CPU before attaching the end cover.

Technical Support FAQ

• Does the NX102-9000 CPU support local hot-swapping of expansion modules?

  No, local expansion modules on the NX I/O Bus must not be removed or added while backplane power is applied to the CPU.

• What is the maximum number of EtherCAT remote nodes supported by this processor?

  The integrated EtherCAT master interface supports up to 64 remote I/O and drive nodes in a single network topology.

• How is program memory retained during power outages?

  The processor uses non-volatile flash memory to preserve sequence programs and non-volatile variables without a battery.

• What serial communication options can be integrated with this processor?

  Option boards can be installed on the front slot to add RS-232C, RS-422, or RS-485 serial communication capability.

• How many local expansion units can be attached directly to the CPU backplane?

  Up to 32 NX-Series digital, analog, or function modules can be attached directly to the local CPU backplane bus.

• What is the maximum total variables memory allocated in this CPU?

  The hardware provides 33.5 MB of dedicated variables memory alongside 5 MB of non-volatile program memory.

• Is OPC-UA server functionality natively supported on the embedded network interfaces?

  Yes, the CPU incorporates native OPC-UA server functionality over its primary Ethernet interface for secure host communication.

• What is the proper procedure for grounding the CPU chassis?

  Connect a low-impedance ground conductor from the CPU ground terminal directly to the panel backplate DIN rail ground strap.
