Electrical & Environmental Attributes

High-Speed Deterministic Processing & Network Execution

The CPU leverages EtherNet/IP and deterministic EtherCAT master capabilities to drive high-speed backplane bus communication velocity across connected modules. Built-in I/O density scaling allows seamless hardware synchronization, while firmware flash compatibility ensures stable cross-platform variable mapping during real-time database transactions and OPC-UA connectivity.

Package Contents

• 1 x Omron NX102-1020 Sysmac NX1 Modular CPU Unit
• 1 x Right-Side End Cover Plate (NX-END02)
• 1 x Terminal Block Assembly for 24 VDC Power Supply Input

Enclosure Mount & Cabinet Wiring Rules

• DIN Rail Assembly: Mount the unit onto a standard 35 mm symmetric DIN rail, maintaining at least 30 mm vertical clearance for airflow.
• Bus Line Termination: Secure the terminal end cover (NX-END02) on the rightmost expansion unit to establish internal backplane continuity.
• Shield Grounding: Ground the EtherCAT and EtherNet/IP shielded twisted-pair cables through low-impedance grounding clamps at the duct entry.
• Hot-Swap Restriction: Power off the main 24 VDC bus prior to attaching or disconnecting local NX I/O expansion slices to prevent interface bus damage.

Frequently Asked Questions

• What primary fieldbus protocols are natively supported on the main physical ports?

  The integrated Ethernet ports natively support EtherCAT Master, EtherNet/IP, standard Ethernet TCP/IP, and OPC-UA server communications.

• Can NX series I/O expansion units be connected directly to the CPU unit?

  Yes, the CPU supports direct side-by-side mounting of up to 32 local NX I/O modules across its internal NX I/O backplane bus interface.

• Does the controller support hot-swapping of connected NX I/O modules during runtime?

  No, hot-swapping local I/O modules on the CPU backplane is not supported; the system power supply must be interrupted before removal.

• How are serial communication interfaces added to the main controller?

  Serial communication capability (RS-232C, RS-422, or RS-485) is achieved by mounting optional NX-series serial communications units to the bus.

• What is the fastest deterministic primary task execution cycle time for motion loops?

  The controller executes logic programs and synchronized motion control loops with a primary task cycle time down to 1 ms.

• What are the specific motion axis constraints for coordinated servo positioning?

  The unit supports a maximum of 15 total axes, strictly categorized as 2 fully synchronized axes, 4 PTP axes, and remaining virtual axes.

• Is external software configuration required for direct enterprise database connection?

  The controller executes direct SQL queries to databases via internal function blocks without requiring middleware translation servers.

• What firmware flash compatibility considerations apply during system maintenance?

  Firmware images must match the project version compiled in Sysmac Studio to prevent execution halts during memory transfer cycles.
