Omron NB7W-TW01B 7-Inch Touchscreen HMI Display
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Omron NB7W-TW01B is a 7-inch touchscreen human-machine interface (HMI) from the Omron NB Series. It provides a panel-mounted operator interface for machine control, equipment status visualization, alarm management and process monitoring. The unit combines a color TFT LCD with 800 x 480 WVGA resolution and 65,536 colors, making it suitable for clear presentation of controls, operating values, trends and diagnostic messages in machine automation, packaging, material handling and compact process-control equipment.
A replacement NB7W-TW01B uses a 24 V DC supply and connects to control equipment through one Ethernet port with RJ45 connector, two USB Host/Slave ports, two RS-232 serial ports, one RS-422 port and one RS-485 port. Ethernet, Modbus TCP and Modbus RTU are supported communication options, depending on the project and system configuration. HMI projects are created and transferred with Omron NB-Designer. A project can be stored in the internal non-volatile flash memory or transferred through USB memory, Ethernet or USB from a PC, so commissioning a spare normally requires transferring the correct project and checking the communication configuration.
Before installing this HMI as a replacement, verify the part number, the existing NB Series project and the required communication interfaces. The panel cutout is 191 mm wide by 137 mm high, and the front panel has an IP65 rating when correctly installed. After replacement, use the built-in on-screen system menu for touchscreen calibration, internal memory checks and communication diagnostic tests, and use NB-Designer for project and communication verification. Confirm the 24 V DC supply, panel installation and connections before returning the machine to service.

Programming and Configuration
Omron NB-Designer is used to create, configure and transfer HMI projects for the NB7W-TW01B. Project files can be transferred directly from a PC through Ethernet or USB, or through a USB memory device. The HMI stores projects in internal non-volatile flash memory.
When commissioning a spare, transfer the correct Omron NB Series project and check the configured communication method against the machine installation. Ethernet, Modbus TCP, Modbus RTU, RS-232, RS-422 and RS-485 connections may be used according to the project and connected automation devices.
Communication and System Integration
The NB7W-TW01B provides one Ethernet interface with an RJ45 connector, two USB Host/Slave ports, two RS-232 serial ports, one RS-422 port and one RS-485 port. This interface combination supports connections to PLCs, controllers, drives, barcode equipment and other automation devices.
Ethernet, Modbus TCP and Modbus RTU are available communication options for NB Series integration, with their use determined by the project and system configuration. After installation, communication diagnostic tests can be run from the HMI system menu, while NB-Designer can be used for project and communication verification.
Diagnostics and Status Indication
The NB7W-TW01B provides an on-screen system menu for touchscreen calibration, internal memory checks and communication diagnostic tests. These functions help separate touchscreen, memory and communication-related issues during replacement commissioning.
NB-Designer can be used to verify the HMI project and communication configuration. For first-line checks, confirm the 24 V DC supply, inspect the Ethernet or serial connections used by the project, and run the relevant system-menu diagnostic test.
Replacement and Spare Part Considerations
For a compatible replacement, match the exact Omron part number NB7W-TW01B and confirm that the machine uses the required NB Series HMI project. Check the 191 mm by 137 mm panel cutout, 24 V DC supply, front-panel IP65 requirement and the Ethernet, USB or serial interface used by the installation.
A spare is not ready for operation until the correct project and communication configuration have been transferred or restored. Use NB-Designer with Ethernet, USB or USB memory transfer as appropriate, then verify the project, communication settings, touchscreen calibration, internal memory and connected equipment. Before ordering, also check whether the installed unit is the NB7W-TW01B or the NB7W-TW01B-V1 revision.
