Description
The Omron NB7W HMI delivers responsive graphical visualization, versatile multi-protocol connectivity, and dependable machine monitoring engineered specifically for automated packaging machines, pump control skids, assembly fixtures, and industrial processing panels.
Intuitive Machine Visualization with the Omron NB7W HMI
Designed to optimize machine-level operator control, the Omron NB7W HMI combines a vibrant 7-inch widescreen TFT display with responsive analogue-resistive touch operation. Featuring 65,536 vivid display colors and a crisp 800 × 480 WVGA resolution, the terminal provides expansive screen space to display real-time process trends, comprehensive diagnostic alarm tables, and multi-variable parameter setpoints simultaneously.
The operator terminal features extensive communication flexibility, incorporating dual independent serial interfaces alongside an optional 10/100 Mbit/s industrial Ethernet port. It communicates natively with Omron CP1E, CP1L, CP2E, CJ2, and CS1 programmable controllers, as well as third-party PLCs and temperature controllers via standard Modbus RTU/TCP protocols, eliminating the need for intermediary communication bridge hardware.
Key Features and Engineering Advantages
- Vibrant Widescreen TFT Display: 16:9 aspect ratio screen with long-life LED backlighting exceeding 50,000 operational hours.
- Multi-Protocol Connectivity: Connects simultaneously across RS-232C and RS-422/485 serial ports alongside high-speed Ethernet loops.
- Comprehensive Data Logging: Integrated USB Host port facilitates automated recipe archiving, operational event recording, and alarm history export to standard USB flash memory.
- Flexible Portrait & Landscape Orientation: Accommodates standard horizontal machinery mounting or vertical narrow-cabinet integration via simple software configuration.
- Rugged Front Ingress Protection: IP65 front bezel seals internal electronic circuitry against high-pressure washdown water, coolant spray, and airborne dust particles.

Frequently Asked Questions
What is the difference between the Omron NB7W-TW00B and NB7W-TW01B models?
The NB7W-TW00B is the standard serial model equipped with RS-232C and RS-422/485 serial ports. The NB7W-TW01B integrates all serial interfaces plus an onboard 10/100 Mbit/s Ethernet port for Modbus TCP networking and remote maintenance.
Can the Omron NB7W HMI log historical alarm trends to an external memory drive?
Yes. Using the integrated USB Host interface, the terminal automatically exports historical alarm logs, operational recipes, and cyclical trend charts into standard CSV spreadsheet files for offline quality auditing.
Which engineering software is used to design operator graphic screens?
Graphic screens, alarm tables, and macro routines are created using the Omron NB-Designer software suite, which features comprehensive vector graphics, animation libraries, multi-language support, and offline simulator tools.
