Configured for synchronized sequence control and motion execution in Sysmac automation platforms, the Omron NX102-1200 (NX102-1200 Sysmac NX1 Modular CPU) provides direct physical/electrical execution. It integrates OPC-UA server functionality, position control, and motion control within a 1 ms primary task cycle. Managing up to 8 synchronous axes and 15 total controlled axes, the CPU executes deterministic instruction sets using 5 MB of program memory and 33.5 MB of variables memory.

Model Architecture & Configuration Matrix

• NX102: Compact modular CPU base unit within the Sysmac NX platform.

Processor Technical Specifications

Deterministic Motion Networks & System Integration

Operating across EtherCAT and Profinet / EtherNet/IP deterministic networks, the controller coordinates motion axes with microsecond-level synchronization. Backplane bus communication velocity allows seamless real-time data exchanges between local NX I/O modules and the main processor core. The hardware environment maintains full firmware flash compatibility via Sysmac Studio, facilitating scalable I/O density scaling across distributed drive and sensor layouts.

Cabinet Installation & Field Cabling Guidelines

• DIN Rail Mounting: Engage top hooks onto a 35 mm DIN rail and push the central unit backward until the lower locking mechanism latches securely.
• Ethernet Cabling: Connect shielded Category 5e or higher RJ45 cables to built-in network ports for industrial Ethernet communication.
• Power Wiring: Connect 24 VDC main power to the push-in terminal block, verifying correct polarity before energizing the unit.
• Grounding Practice: Route a heavy-gauge copper grounding strap directly from the functional ground terminal to the main panel enclosure ground rail.
• I/O Bus Expansion: Attach adjacent NX I/O modules along side guide tracks, terminating the rightmost side with the mandatory end cover.

Frequently Asked Questions

• Does the NX102-1200 CPU support hot-swapping of adjacent local NX I/O slice modules?

  No. You must completely isolate main supply power to the processor base before adding or removing local backplane I/O slices.

• What is the maximum number of controlled motion axes supported by the processor?

  The unit manages up to 15 total axes, including 8 synchronous motion axes, 4 point-to-point (PTP) axes, and virtual positioning axes.

• How is OPC-UA protocol integration handled on the NX102-1200 hardware platform?

  An integrated OPC-UA server runs directly on the CPU hardware, enabling secure machine-to-machine data exchange without external gateways.

• What primary task cycle rate does the internal processor core execute?

  The primary task execution cycle operates at 1 ms, delivering deterministic updating for motion commands and sequence logic.

• Is external 24 VDC power required to operate the CPU controller?

  Yes. The unit requires an external regulated 24 VDC power supply connected to the front terminal block to energize internal logic.

• What function does the end cover unit serve on the CPU backplane?

  The end cover protects exposed backplane bus contacts on the rightmost slice and terminates internal communication signal lines.

• How is project memory organized between logic code and runtime data?

  The controller allocates 5 MB of dedicated program memory for execution code and 33.5 MB of variables memory for process data storage.

• How are firmware updates managed on the CPU processor?

  Firmware upgrades are executed via Sysmac Studio over an active Ethernet connection or transferred via an SD memory card.
