The Omron NB7W-TW00B, serves as the primary NB7W Touch Screen HMI utilized to execute direct operator visual interface and real-time controller register interactions across SYSMAC PLC network platforms.

Model Designation Analysis

• NB7W: Represents the 7-inch wide-screen display chassis geometry.
• T: Indicates active-matrix color TFT LCD panel construction.
• W: Specifies WVGA wide-aspect display format (800 x 480 pixels).
• 00: Designates standard serial-only connectivity (COM1 RS-232C and COM2 RS-232C/422/485) without USB host/Ethernet ports.
• B: Identifies the black bezel housing finish.

Physical and Electrical Parameters Matrix

Deterministic Serial Bus Execution and Firmware Architecture

The display terminal interfaces with host controllers via dedicated serial channels to preserve deterministic backplane bus communication velocity across industrial networks. System flash memory ensures complete firmware flash compatibility, maintaining consistent screen redrawn rates and eliminating variable execution delays during high I/O density scaling.

Factory Supply Kit

• 1 x NB7W-TW00B Touch Screen HMI Terminal
• 4 x Panel Mounting Clips
• 1 x 3-pin DC Power Input Terminal Connector Block
• 1 x Synthetic Front Bezel Sealing Gasket

Field Cabinet Mounting and Electrical Instructions

• Cut panel mounting hole to exact dimensions of 175.0 mm horizontal by 121.0 mm vertical.
• Verify synthetic rubber seal is fully seated within front bezel channel for IP65 front enclosure compliance.
• Insert HMI into cutout and tighten 4 mounting clips to torque limits between 0.5 N m and 0.6 N m.
• Wire 24 VDC input supply lines (AWG 14 to AWG 22) into removable 3-pin power block terminal.
• Provide at least 100 mm clear clearance behind rear housing surface to allow passive convective airflow.

Technical Performance Questions and Answers

• What display panel resolution and color capabilities are provided by this HMI?

  The unit features a 7-inch TFT screen supporting 800 x 480 pixels (WVGA) with 65,536 displayable colors.

• Does the NB7W-TW00B terminal contain an integrated RJ45 Ethernet port?

  No, the 00 code variant denotes serial-only communication without integrated Ethernet hardware.

• What physical protection rating is provided on the front control face?

  The front bezel surface provides IP65 ingress protection when mounted with its sealing gasket.

• What serial interfaces are integrated into the rear connectivity panel?

  The terminal provides COM1 (RS-232C) and COM2 (RS-232C/422/485) serial interfaces for controller communication.

• What voltage range is acceptable on the 24 VDC supply terminal block?

  The internal power regulator accepts continuous input voltages ranging from 20.4 VDC to 27.6 VDC.

• How are project files transferred to the device without Ethernet?

  Project runtime files are loaded via the slave USB connection or point-to-point RS-232C serial communication.

• What wire size and earthing standard should be applied to the functional ground?

  Connect AWG 14 minimum copper wire directly from FG terminal pin to a Class D earth ground (under 100 ohms).

• How is the hardware system configuration menu accessed during bootup?

  Touch two diagonally opposing corners of the screen matrix simultaneously during initial startup sequence.
