KEYENCE XG-8000 Line Scan Visual Debugging Guide

Click Shading Correction to display the intensity curves before and after correction.

Set Correction Region: X center, width, and average number of lines in the Y direction (it is recommended to take the average of multiple lines).

Set Smooth Range: A narrower range is suitable for local brightness changes, while a wider range is suitable for overall gradients.

Click Execute, and the calibration values will be automatically written into the camera's internal system.

The correction values can be saved to the SD card (default path SD2: xg linecam ) and restored through Load Correction Values.

Note: The maximum correction magnification is 5 times. If adjustments are still needed after calibration, please perform calibration again and do not manually modify the gain.

5.3 LED Threshold Customization

The brightness/sharpness LED threshold on the back of the camera can be modified in Linescan Calibration. For example, changing the threshold of Brightness LED 3 from 192 to 240, so that only very bright areas trigger the third light, is suitable for high reflective materials.

Communication interface configuration and PC software connection

XG-8000 provides five communication methods, and engineers need to choose according to the requirements of the on-site PLC or upper computer.

6.1 RS-232C (Port 1: RJ-11, Port 2: D-sub 9-pin)

Default usage: Port 1 is used for data output/command control, and Port 2 is used for touch screens (CA series).

Parameters can be set: baud rate (9600~230400 bps), data bits of 8, stop bits of 1/2, parity check of none/odd/even.

Wiring: Use OP-26487 (2.5m direct connection) or self-made crossover wire. Pay attention to the signal GND and power GND being grounded together to avoid voltage differences.

6.2 Ethernet

Connection method: Supports 1:1 crossover (recommended OP-66843 Gigabit crossover) or direct connection through a switch (Category 5e or above STP shielded wire).

Protocol: TCP/IP (ASCII commands), PLC Link, EtherNet/IP, and FTP client.

Settings: IP address, subnet mask, and default gateway are set in the system configuration. When using 1000BASE-T, it is necessary to use Category 5e or higher.

6.3 USB (for dedicated software only)

Usage: Only for connecting XG VisionEditor/VisionEerminal, does not support ordinary USB devices such as mice and USB drives.

Driver installation: The first connection requires installing the USB driver from the CD (located in driver USB). Under Win7, drivers need to be manually updated through the Device Manager.

Limitation: Only one controller can be connected to the same PC; Excessive cable length or the use of extension cords can cause instability.

6.4 CC-Link（CA-NCL10E）

Station type: Ver.1.10 or Ver.2.00 remote device station.

Communication speed: 156 kbps~10 Mbps, total extension distance is rate dependent (≤ 100 m at 10 Mbps).

Terminal resistor: Select the matching terminal resistor according to the cable model and install it between the DA and DB ends of the network.

Settings: Set the number of occupied stations (1-4) and loop settings (1x/2x/4x/8x) in the system configuration. After changing the settings, the controller and main station must be restarted.

6.5 Parallel I/O (40 pin flat cable)

Expand 22 universal inputs and 22 universal outputs (partially high-speed output F_OUT) using OP-51657 (3-meter ribbon cable).

Default allocation: IN0-IN15, OUT0-OUT21. Functions can be redefined through system variables such as Trg1Ready and CMDReady.

Attention: COMOUT2 terminals 17 and 40 are connected internally, ensuring that both have the same potential.

Handheld controller and special start combination key

The handheld controller OP-84231 provides the following core functions:

8-way joystick: Move the cursor and confirm in the center.

TRIGGER (No.3): Trigger all cameras at once; Long press to enter continuous triggering.

Function (No.1): Call out function menu.

RUN/STOP switch: Switch between run/edit mode.

Special startup combination key (for fault recovery):

Combination key function

No.2+Power ON initializes the controller to default settings and formats the SD1 card (all data will be lost)

No.1+Power ON forced display of initial startup screen (language/resolution selection)

No.1+8-way joystick+power ON forced offline mode start

No.6+Power on, obtain network settings through BOOTP

Runtime key combination (default):

No.1+No.5 (or No.7+No.5): Save the screenshot to SD2.

No.1+No.2 (or No.7+No.2): Send a reset signal in operation mode.

No.1+No.4 (or No.7+No.4): Switch screen display type (raw/filtered, etc.).

Common fault diagnosis and troubleshooting

8.1 No display after power on

Check if the 24V power supply is connected to A1/A2 and the polarity is correct.

Confirm that the monitor supports SVGA (800 × 600) or XGA (1024 × 768) with a vertical frequency of 60 Hz.

Check if the SD1 card is inserted and functioning properly (the controller cannot start without the SD1 card).

If the screen is still black, press and hold the No.1 key while powering on to force entry into the initial settings screen.

8.2 The image is completely black (but triggers normally)

Check if the aperture is open and if the lens cover is removed.
