Key questions and answers

Question 1: What scenarios are the four operating modes of FH/FHV applicable to?

answer

Standard: Universal scenario, most comprehensive functions, fastest single measurement speed

Double Speed Multi input: Ultra high beat production line, dual core alternating processing, supports the fastest trigger

Non stop adjustment: The production line cannot be stopped, and parameters and processes can be adjusted online

Multi line Random trigger: 1 control for multiple lines, capable of independently controlling up to 8 production lines, specifically designed for the FH series

Question 2: What is the measurement scene? How much can be built at most? How to break through the quantity limit?

answer

The scene is a complete visual inspection process (image input+processing+judgment+output)

Default maximum of 128 scenes per group

Breakthrough method: Use Scene Group or Scene Group Conversion tool, supporting over 128 scene management

Question 3: What is the use of parallel processing? How to open and use it?

answer

Function: Utilizing multi-core CPUs to execute detection processes in parallel, significantly reducing cycle time

Enable: System Settings → Operation Mode → Parallel Execute Set to ON

use:

Automatic Parallel: System Automatic Classification Parallel

Manual Parallel: Add Parallelize/Parallelize Task/Parallelize End Unit Custom Parallel Block
