RUN mode: formal operation, result output, data logging, statistical display.

Detection tools (10 core categories)

1. Shape detection

Pattern Search: Template matching with the highest accuracy.

Graphic Search: Contour priority, low contrast stability.

Flexible Search: Multiple templates (36) compatible with differences.

Sensitive Search: Subdivide grids and detect small differences.

2. Size/color/edge detection

Area/Labeling/MultiColors: Area, counting, multi-color (4-color) sorting.

Position/Width/Count/Angle: Edge position, width, quantity, angle.

Bright/HOU: Brightness and hue judgment, resistant to light fluctuations.

3. Application detection

Grouping: Multi template classification (64), product segmentation.

Defect: Region segmentation comparison, scratch, dirt, and missing material detection.

Advanced features

1. Position correction

Triggering error ENABLE not ready waiting for enable, debounce

Parallel timeout handshake does not respond. Check PLC timing and extend timeout

SD card abnormal lock/damage unlock, format, replace card

Key issues

Question 1: What is the core difference in functionality and capacity between C20/C25 and C10/C15?

answer:

C20/C25: Supports dual cameras, single bank 128 item detection, with full functionality of graphic/flexible/labeling/log monitoring.

C10/C15: Only single camera, single bank 32 item detection, only open basic template and brightness detection, without advanced contour and log functions.

Question 2: What is the function of ZFX-C position correction? What calibration methods are supported?

Answer: Function: When the workpiece deviates/rotates, the detection area is automatically corrected to ensure stable measurement. Support methods: 8 types including edge position, area, marking, template, dual template, angle, contour, and graphic search.

Question 3: What is the difference between “handshake mode ON/OFF” in parallel interfaces? How to choose on-site?

answer:

OFF (asynchronous): The result is directly output, locked by GATE signal, simple and fast, suitable for high-speed single line.

ON (synchronous): Transmission requested by DSA signal, anti loss, more stable, suitable for multiple data/PLC strict timing.

Selection: OFF for high-speed single line; Multi data, long-distance, and error proof ON.
