The Omron NX102-1220, also cataloged as the NX102-1220 Sysmac NX1 Modular CPU, operates as a dedicated hardware component for multi-axis sequence execution and real-time motion control within Sysmac automation architectures.

Part Number Code Structure

• NX102: Compact NX1 series machine automation controller hardware platform.
• 12: Integrated database connectivity functionality with 8 synchronous motion axes capability.
• 20: 5 MB program execution memory specification with OPC-UA client/server integration.

Operating Parameters

Deterministic Network Bus Architecture

The module interfaces directly with EtherNet/IP deterministic networks via the NX bus system to maintain synchronous data exchange. Optimized backplane bus communication velocity allows high-density I/O density scaling profiles, while firmware flash compatibility ensures zero execution delays during high-speed analog loop processing.

Scope of Delivery

• 1 x Omron NX102-1220 Sysmac NX1 Modular CPU
• 1 x End cover unit (NX-END02)
• 1 x Power supply connector
• 1 x Hardware installation guide

Physical Cabinet Installation

• Mount the controller vertically onto a standard 35 mm DIN rail inside a protective industrial enclosure.
• Provide at least 30 mm of free air space above and below the module to facilitate natural thermal dissipation.
• Connect the main functional ground terminal directly to a single-point earth ground bar using a short green/yellow wire.
• Confirm that the bus connector side cover is securely snapped into place before applying power to the unit.
• Route high-voltage AC cables separately from low-voltage Ethernet and NX bus communication lines.

Technical Support FAQ

• What is the primary task cycle time limit for motion axis calculations on the NX102-1220 CPU?

  The controller executes the primary periodic task cycle at a maximum speed of 1 ms for synchronized motion routines.

• Does the NX102-1220 unit support direct relational database integration without external gateways?

  Yes, the CPU includes built-in database client software for direct SQL connections to MySQL, Oracle, and MS SQL.

• How many remote I/O nodes can be connected via the built-in EtherCAT master port?

  The EtherCAT master port supports up to 64 remote I/O slave nodes operating on a deterministic field network.

• What communication option boards can be inserted into the front option card slots?

  The CPU accepts serial communication option boards supporting standard RS-232C, RS-422, and RS-485 interfaces.

• Is an external SD memory card mandatory for running user PLC programs?

  No, user programs run from internal non-volatile memory; SD cards are used for logging, backups, and recipe storage.

• What is the maximum number of local expansion NX I/O modules supported on the CPU rack?

  The CPU backplane interface supports up to 32 NX series expansion units mounted directly on the local DIN rail.

• How does the unit manage clock retention during total external DC power outages?

  An internal battery retains clock calendar data and non-volatile variables during extended power failure events.

• Can the USB service port be utilized for real-time EtherCAT field bus communication?

  No, the built-in USB port is restricted exclusively to programming, firmware maintenance, and Sysmac Studio setups.
