Product Overview

The Omron NB3Q-TW01B-V1 is the NB-series 3.5-inch QVGA color touch HMI with a full set of I/O: 10/100 base-T Ethernet, USB-A host (for a USB memory stick), USB-B slave (for CX-One project upload), and RS-232C (COM1). Pick the TW01B-V1 for a tight-panel machine where an Ethernet link to a CJ1 / CP1 / NJ / NX PLC is the primary connection, but the operator also needs USB-stick recipe transfer on the floor. The 320 x 240 pixel TFT color screen and the white LED backlight keep the panel readable at the typical shop-floor brightness, and the IP65 front seal suits washdown-tolerant panels.

USB host for recipe transfer

The USB-A host port takes a standard USB memory stick (the FZ-MEM2G / FZ-MEM8G industrial-grade sticks are the typical pick). Operators can pull a recipe from the HMI, drop it on the stick, and carry it to the next machine -- or push a new recipe from the stick without a PC at the line. The USB-B slave port on the bottom edge takes a standard USB cable back to the engineering PC for project upload / download.

NB family and TW code splits

The TW01B-V1 is the full-feature NB3Q. Pick the NB3Q-TW00B instead for a stripped Ethernet-only variant that drops the USB host. The NB5Q-TW01B-V1 is the 5.6-inch QVGA sibling with the same port set; the NB7W-TW01B-V1 is the 7.0-inch WVGA Ethernet + USB-host sibling; the NB10W-TW01B is the 10.1-inch wide-format sibling. All NB-series panels run the same NB-Designer project, so a TW01B-V1 project moves to a 7-inch NB7W without rework -- just resize the pages.

Before ordering

Confirm the panel cutout is 119.0 x 92.5 mm with 1 to 5 mm panel thickness. Confirm the HMI cable run to the PLC is in spec for Ethernet (Cat 5e or better, 100 m max). Confirm the FZ-MEM2G / FZ-MEM8G industrial-grade USB stick is in stock for recipe transfer. Pair with the NB3Q-KBA04 protective sheet for shop-floor touch life. Pick the NB5Q-TW01B-V1 for a 5.6-inch screen with the same Ethernet + USB-host port set.

Best-Fit Applications

  • Compact operator panel on a small benchtop machine where panel space is at a premium
  • Compact Ethernet-only HMI for a CJ1 / CP1 / NJ / NX PLC link, replacing an older NS5 in a like-for-like retrofit
  • Recipe-display station on a packaging line using FZ-MEM2G / FZ-MEM8G USB sticks for product change-over
  • Status / alarm display on a multi-station conveyor where one HMI is mounted on each station
  • Skid-mount control where the operator needs a compact touch interface plus Ethernet diagnostics

Buying Checklist

  • Pick NB3Q-TW01B-V1 for a compact 3.5-inch QVGA Ethernet + USB-host + USB-slave + RS-232C NB-series touch HMI at 24 VDC.
  • Pick NB3Q-TW00B instead for an Ethernet-only stripped variant without the USB host (no USB-stick recipe transfer).
  • Pick NB5Q-TW01B-V1 instead for a 5.6-inch QVGA screen with the same full port set.
  • Pick NB7W-TW01B-V1 instead for a 7.0-inch WVGA screen with the same full port set.
  • Pair with FZ-MEM2G / FZ-MEM8G industrial USB memory sticks for recipe transfer on the shop floor.
  • Pair with NB3Q-KBA04 protective sheet for shop-floor touch life (replaceable without breaking the IP65 front seal).

FAQ for NB3Q-TW01B-V1

What is the difference between NB3Q-TW01B-V1 and NB3Q-TW00B?
Both are 3.5-inch QVGA Ethernet NB3Q HMIs. The TW01B-V1 is the full-feature variant: Ethernet + USB-A host + USB-B slave + RS-232C (COM1). The TW00B is the stripped variant: Ethernet + USB-B slave + RS-232C (COM1) only -- no USB host, so a memory stick cannot be plugged in for recipe transfer. Pick the TW01B-V1 for a recipe-driven line. Pick the TW00B for a status / alarm panel where the USB-stick function is not needed. Both panels run the same NB-Designer project.
Does the NB3Q-TW01B-V1 support Modbus-TCP or only FINS?
It supports both. The built-in Ethernet port runs FINS / UDP and FINS / TCP for native Omron communications to CJ / CP1 / NJ / NX, plus Modbus-TCP for third-party devices. The COM1 RS-232C port runs Host Link (SYSWAY), NT Link 1:N, and Modbus-RTU master / slave via NB-Designer protocol macros. The typical small-machine build uses Ethernet FINS to the CJ1 / NJ and a separate RS-232C port to a barcode reader or a serial-label printer.
Can the NB3Q-TW01B-V1 replace an older NS5 / NS8 HMI?
Yes, for most projects. The NB3Q panel cutout is 119.0 x 92.5 mm, which is much smaller than the NS5-SQ10B-V2 cutout (184 x 132 mm) -- a direct panel replacement requires adapter bezel work, but the NB5Q-TW01B-V1 (5.6-inch) and NB7W-TW01B-V1 (7.0-inch) cutouts are closer to the NS class. Project migration from CX-Designer to NB-Designer is not automatic -- the project has to be rebuilt in NB-Designer. Pick the NA5-12W101B (Sysmac NA-series) when the Sysmac Studio / NA Studio programming environment is the standard.
What does the -V1 suffix on the NB3Q-TW01B-V1 mean?
The -V1 is a hardware / firmware revision marker for the NB-series. The TW01B and TW01B-V1 share the same datasheet and project compatibility -- a TW01B (non-V1) project loads on a TW01B-V1 without rework, and vice versa. The -V1 is the currently-active catalog entry. If the warehouse shows only the TW00B (no -V1), it is functionally equivalent for the non-V1 part -- the differences are internal firmware features that don't affect the user project.
