Omron NB10W-TW01B Interactive Display HMI

The Omron NB10W-TW01B is a high-performance interactive display terminal belonging to the NB Series of human-machine interface (HMI) devices. This touch screen HMI features a 10-inch wide TFT LCD with LED backlight technology, providing a vivid, high-contrast graphical interface for operators to monitor and control machinery and processes. The NB10W-TW01B is engineered for industrial environments, offering a durable front bezel rated IP65 for protection against dust and water jets, allowing it to be installed on machine panels or in washdown areas. The terminal communicates with PLCs, drives, robots, and other automation devices through multiple onboard ports, making it a central component in modern manufacturing cells.

Display and Touch Technology

The wide format 10-inch screen, with an aspect ratio of 16:9, provides ample area for displaying machine status graphics, trend charts, alarm lists, and control buttons. The display resolution is typically 800 by 480 pixels for the wide model, offering clear rendering of text and images. The LED backlight ensures consistent brightness exceeding 400 candelas per square meter, and its long lifetime of more than 50,000 hours to half brightness eliminates the need for routine lamp changes. The resistive touch technology works with gloved fingers or stylus, making it practical for industrial use. The touch panel is optically bonded to the LCD to reduce glare and improve readability under bright overhead lighting. The screen offers wide viewing angles, typically 70 degrees in all directions, allowing operators to see information clearly even when standing off center.

Communication Capabilities

The NB10W-TW01B is equipped with a comprehensive set of communication ports to ensure compatibility with a broad range of automation devices. An Ethernet port supports high-speed data exchange with PLCs using protocols such as Omron FINS, Modbus TCP, and Ethernet/IP. Two serial ports are provided: one RS-232C and one RS-422/485. The RS-232C port is suitable for direct connection to a local PLC or programming computer, while the RS-422/485 port allows long-distance multidrop networking of up to 32 devices. The HMI also includes a USB port for connecting a mouse, keyboard, or USB memory stick. The USB memory interface enables easy transfer of screen projects, data logging exports, and recipe updates without requiring a network connection.

Software and Screen Design

The NB-Designer software is the dedicated programming environment for the NB series HMI’s. This Windows-based software provides a drawing toolbar, object library, and tag database to create interactive screens. Users can draw static graphics such as vector shapes, import bitmap images, and place dynamic objects that reflect PLC values. Objects include numeric indicators, text displays, bar graphs, trend charts, alarm displays, data entry fields, and pushbuttons. The software supports multi-language text tables, enabling the same project to be used on machines shipped to different countries without re-engineering. Macros written in a script language allow advanced calculations, conditional logic, and data conversion on the HMI itself. The software includes a simulation mode, allowing the developer to test screen navigation and tag behavior offline before downloading to the hardware.

Recipe and Data Management

The NB10W-TW01B includes built-in recipe management functionality to simplify product changeovers. Recipe data, consisting of sets of parameters such as temperature setpoints, time values, and speed targets, are stored on the HMI’s internal flash memory or an external USB drive. Operators can select a product name from a list, and the HMI downloads the corresponding parameter set to the PLC, updating hundreds of registers in seconds. Conversely, the HMI can upload current machine settings into a recipe record for backup or optimization studies. Additionally, the HMI supports data logging, where selected PLC registers are sampled at defined intervals and stored as time-stamped CSV files. These log files can be retrieved via USB or network for analysis in external statistical software, supporting quality management and predictive maintenance initiatives.

Alarms and Historical Events

An integrated alarm system in the NB10W-TW01B monitors up to thousands of alarm conditions defined by the user. Each alarm has a text message, a priority level, and optionally a trigger condition such as a bit becoming true or a value exceeding a limit. When an alarm occurs, the HMI can display a pop-up message, sound a buzzer, write to the alarm history log, and optionally send a notification via email if the network configuration permits. The alarm history screen allows operators to review past alarms with timestamp, acknowledgment status, and resolution notes. This historical view is essential for diagnosing intermittent faults and proving compliance with safety regulations.
