The Omron NB10W-TW01B, also cataloged as the NB10W Programmable Terminal, operates as a dedicated hardware component for graphical human-machine interface and real-time process visualization within industrial automation networks. It executes operator control input and visual alarm processing via a 10.1-inch TFT LCD screen, exchanging serial and Ethernet data directly with PLC controllers across dedicated serial and Ethernet physical layers.

Hardware Variant and Interface Identification

• NB Series: Compact HMI programmable terminal architecture
• 10W: 10.1-inch wide-screen display format (800 x 480 pixel resolution)
• T: TFT color LCD display with 65,536-color rendering capability
• W01: Dual communication capability incorporating Ethernet, RS-232, and RS-422/485 serial channels
• B: Standard black enclosure frame with integrated touch panel

Operational and Physical Specifications

Ethernet Determinism and Firmware Flash Compatibility

The hardware interfaces directly with Omron CP, CJ, and CS series PLCs via EtherNet/IP and FINNS communications over deterministic local networks. Internal firmware flash compatibility ensures seamless protocol handshake verification during runtime execution without causing network scan delay or dropping asynchronous data frames. Direct memory mapping eliminates protocol conversion latencies, maintaining deterministic synchronization between PLC image registers and screen object tags.

Standard Package and Accessories

• 1 x Omron NB10W-TW01B Programmable Terminal unit
• 1 x Power supply connector block (3-pin terminal)
• 4 x Panel mounting brackets and fixing screw sets
• 1 x Installation rubber gasket (pre-installed)

Panel Mounting and Installation Requirements

Cutout and Enclosure Installation

• Prepare a panel cutout measuring 257.0 mm x 199.0 mm (W x H) in an enclosure wall with a thickness of 1.6 mm to 4.8 mm.
• Insert the terminal with the rubber sealing gasket properly positioned to maintain environmental ingress protection ratings.
• Tighten the four panel mounting bracket screws uniformly to a torque of 0.5 to 0.6 N m to secure a dust-tight seal.

Power Supply and Signal Cable Wiring

• Supply 24 VDC power using class 2 dedicated wiring routed away from AC power lines and inverter output cables.
• Ensure the functional earth terminal (FE) is grounded directly to a low-impedance panel grounding point using a wire of at least 1.25 mm2.

Technical Questions & Answers

• What input voltage range does the terminal accept at its power terminals?

  The unit requires a nominal 24 VDC power supply operating within an acceptable voltage window of 19.2 VDC to 28.8 VDC.

• Can screen project data be updated using a standard USB storage device?

  Yes, runtime screen projects and system firmware can be updated via the USB Host interface using a FAT32-formatted USB drive.

• Does the RS-422/485 port require an external line termination resistor?

  For long-distance serial runs at high baud rates, activate or install an external 120 Ohm termination resistor across RXD/TXD lines.

• How is touch screen calibration executed if touch point alignment shifts?

  Access the system menu during startup by pressing designated screen corners to invoke the built-in touch calibration routine.

• Are hot-plugging actions supported on serial communication interfaces?

  Disconnecting or reconnecting serial RS-232 or RS-422/485 cables under active power can damage transceiver ICs and is strictly forbidden.

• What memory allocation is provided for historical data logging and alarms?

  The 128 MB internal flash memory stores the operating system, project graphics, alarm history logs, and recipe datasets.

• What steps prevent electrical noise interference on the Ethernet connection?

  Use Category 5e or higher shielded twisted-pair (STP) Ethernet cables with metal-shielded RJ45 connectors grounded at the switch end.

• How does the unit behave when DC supply voltage drops below 19.2 VDC?

  Under-voltage conditions cause the internal power monitoring circuit to reset the display processor, halting runtime execution safely.
