Concept of Measurement Processing
When the FH receives a measurement trigger from the PLC or other external device, the image input
from a Camera, measurement processing, and output of measurement results (e.g., OK/NG judge-
ment results) are executed in the order that those processing items are registered in the measurement
flow.

In the measurement flow, you can change the processing to execute based on the inspection results
or input conditions of the vision inspection.
You can use macro processing to execute pre-packaged processing items and functions in the FH to
create original programs. This allows you to create original measurement processes, display process-
ing, input and output processing, and settings dialog boxes that are custom-tailored to your applica-
tion.
