Configured for integrated PLC control execution and graphical display operations in DeviceNet fieldbus networks, the Omron NSJ5-TQ01B-G5D (NSJ5-TQ01 Human Machine Interface) provides direct physical/electrical execution.

Nomenclature Configuration

• NSJ5: Integrated HMI-PLC unit with 5.7-inch screen size footprint.
• TQ01: TFT color LCD panel with QVGA display resolution.
• B: Black enclosure frame finish.
• G5D: Built-in CJ1-series PLC processing engine with DeviceNet master interface and 24 VDC input.

Functional Specifications

PLC Engine Integration and System Memory Management

The integrated CJ1 controller architecture maintains high backplane bus communication velocity Licences and deterministic internal memory mapping between the PLC engine and display hardware. Dedicated internal memory channels eliminate external communication latencies during high-density I/O register exchanges. Flash memory management reserves dedicated blocks for function block program data (1024 KB), comment files (64 KB), program index files (64 KB), and symbol tables (64 KB). System execution maintains strict firmware flash compatibility across CX-One development environments.

System Supply Items

• 1 x Omron NSJ5-TQ01B-G5D Integrated HMI-PLC Unit
• 1 x 24 VDC Power Supply Terminal Plug
• 1 x DeviceNet Fieldbus Connector Block
• 4 x Panel Mounting Clamps and Retaining Screws

Mechanical Installation and Power Grounding

Door Panel Cutout

Cut a clean rectangular opening in the enclosure door according to standard panel dimensions. Maintain at least 100 mm clear perimeter space around top, bottom, and side ventilation slots to enable natural convection airflow.

Bezel Fastening

Verify that the perimeter rubber seal is properly seated inside the bezel channel. Insert the unit into the door opening and tighten all four clamp brackets evenly to maintain IP65 front panel sealing.

Power and Earth Ground Connections

Connect a regulated 24 VDC power source using shielded 16 AWG conductors. Wire the Functional Ground (FG) terminal directly to the central enclosure earth bus using a short, low-impedance copper conductor to mitigate high-frequency electrical interference.

Technical FAQ

• How is data exchanged between the internal PLC engine and the display panel?

  Internal bus routing maps PLC memory areas directly to screen tags, eliminating serial baud rate delays and ensuring microsecond-level register updates.

• Does the unit support hot-swapping connected DeviceNet slave nodes?

  DeviceNet network nodes can be connected or disconnected without powering down the master, provided terminal resistors and trunk cable integrity remain intact.

• What happens to local I/O execution if 24 VDC power drops below threshold?

  A drop below 20.4 VDC triggers an immediate controller fault state, halting program execution and resetting digital outputs to safe zero states.

• How does the system handle function block memory allocation?

  Function block code is executed from dedicated 1024 KB flash program memory, preserving program execution structure during main DC power loss.

• What routing rules apply to DeviceNet trunk and drop cables?

  DeviceNet cables must run through grounded metal conduits separated from 230/400 VAC power lines and variable frequency drive motor leads by at least 300 mm.

• What expansion limit applies to the basic processing controller variant?

  Basic controller configurations support a maximum of 1 expansion rack, limiting total local I/O module footprint compared to advanced controller models.

• What precautions are required during program download via CX-One?

  Maintain continuous 24 VDC logic power throughout the transfer. Loss of power during firmware or flash sector writes corrupts memory indexes.

• What mounting angle is required for optimal cabinet thermal dissipation?

  Mount the display terminal vertically within 30 deg of perpendicular to prevent heat buildup inside the rear CPU and power supply enclosure.
