Specifying Logging Conditions for Images
If you need to specify conditions for logging images, you should use the processing item logging function.
For example, the system logging function logs all images if the overall judgement is NG or OK.
Processing item logging (image logging), logs images only when a condition is met.
The following examples illustrate how processing item logging can be used.
Possible Saving Conditions
Images can be logged when measurement data or result data of a calculation falls within a specified range.
Example 1: Image logging is performed if the individual judgements of three measurement units U1, U3, and
U5 are NG.
Example 2: Image logging is performed if the edge with for a measurement unit is below a set value.
Destination of Images
This diagram shows the destination for saving if [Save to memory + file] is selected in the system image logging
settings.
If [Logging setting] is set to [Image logging], select [None] (default).
If you set more than one Image Logging processing unit in the measurement flow, the most recently executed
image logging is enabled.

n. Image Logging
An NG image is logged only when the results
