Monitoring Measurement Value Trends; Logging Measurement Values And Measurement Images - Omron FH-1 series User Manual

Monitoring Measurement Value Trends

By monitoring the trends in measurement values, the occurrence of defects can be prevented in advance and
this information can also be helpful in NG error occurrence cause analysis. Use the [Trend Monitor] processing
item to monitor the measurement values.
Refer to Trend Monitor in the Vision System FH/FZ5 Series Processing Item Function Reference Manual (Cat
No. Z341).

Note
• If the measurement value is within the alarm range, the [Warning] message is displayed.
• If a result output-related processing item is used, this allows for output to external devices when a warning occurs.
• Through trend monitor judgement, trends can be managed and NG error images can be saved.
To save only NG error images identified by trend monitor judgement, create settings so that overall judgements from
processing units other than [Trend Monitor] are not included in the judgement.

Logging Measurement Values and Measurement Images

What Is Logging?
Logging is used to save Camera input images or measurement results when executing measurements.
Depending on what is being saved, there is image logging (camera input images) and data logging
(measurement results)
File type and save method can be set in the Logging setting menu of System settings.
There are two logging functions, system logging and logging that is performed by the processing item.
Image Logging
• System Logging
To enable system logging, set the logging setting in the system settings.
The image logging process is executed after processing of the measurement flow is completed.
• Processing Item Logging
For those processing items that include logging function, Image Logging and Image Conversion Logging
are two available logging functions.
To enable processing item logging, register the processing items in the measurement flow.
This logging function allows you to more flexible set the logging conditions than system logging. If there is
more than one Image Logging Unit in the measurement flow, image logging is performed based on the
logging conditions for the most recently executed Image Logging Unit.
