Logging Measurement Values and Measurement Images

Logging is a function for saving camera input images or measurement results when executing measurement.

There are 2 different logging methods.

When logging images that are currently displayed
Logging current image [Save last logging image]
When automatically logging images during measurement
Setting Logging Conditions [Logging setting]

Images and measurement data can be saved in USB memory, which makes them useful for the following kinds of adjustment.

Illustration of logging setting methods and usage examples

Logging Current Image [Save Last Logging Image]

This section explains the method for logging the latest input image being displayed.

On the Main screen, tap [Measure] menu - [Save last logging image].
The Logging Setting window is displayed.
Set the logging images save destination.
Specify the image file save destination (RAMDisk or USB memory).
Edit the file name as required.
Tap [OK].
After the logging operation is complete, the Save Last Logging Image window closes.

Setting Logging Conditions [Logging Setting]

Set the logging timing and the save destination.

On the Main screen, tap the [Measure] menu - [Logging setting].
The Logging Setting window is displayed.

Set the logging conditions for images.

Setting item	Setting value [Factory default]	Description
Image Logging	[None]	No images are saved. When logging images with the processing item "Image Logging", select [None].
	Only NG	Only images with an overall judgement of NG are saved.
	All	All measured images are saved. Note, however, that some images may not be saved if "Measurement" is set in "Logging priority" in step 4.

Set the logging images save destination.

Reference

In order to perform fast logging, image files are first saved in the controller memory. Note, however, that the controller memory for saving images is a ring memory. If the maximum number of save images is reached, images will be overwritten starting with the oldest saved image if further images are saved.
About Number of Logging Images
The controller memory is cleared if the power is turned off again.
To keep images, select "Save to memory + file" and save images to USB memory, etc.

Setting item	Setting value [Factory default]	Description
Destination	[Save to memory]	Saves to the controller memory.
Destination	Save to memory + file	Images saved to the controller memory are saved to a USBDisk or RAMDisk as files.

When "Save to memory + file" in "Destination" is selected, set the destination and file names.

Setting item	Setting value [Factory default]	Description
Folder name	[RAMDisk] USBDisk	Specify the image file save destination (RAMDisk or USB memory). Logging images are saved in the specified save destination folder.
Prefix	-	Sets the prefix for the save file name. The set character string is added at the beginning of the name of the save file.
Switch saving folder by scene	Checked [Unchecked]	If checked, folders that correspond to scene numbers are automatically created and image files are divided by scene and saved.
Switch saving folder by judge	Checked [Unchecked]	If checked, OK/NG folders are automatically created and image files are divided by scene and saved.

"Save to memory + file" setting example and save destination

Example of setting	Destination
Folder name: USBDisk Prefix: image_ "Switch saving folder by scene": Checked "Switch saving folder by judge": Checked	Saving will be performed as follows for the settings example on the left OK image save destination: \USBDisk\S000-000\OK\image_(Measurement ID).IFZ NG image save destination: \USBDisk\S000-002\NG\image_(Measurement ID).IFZ

Set the image logging priority conditions.

This setting is only valid when "Save to memory + file" is selected in the image logging saving conditions.

When the measurement takt time is short, time lag may occur with writing from the controller memory to the RAMDisk or USBDisk and temporary absences of free capacity in the controller memory may occur. Select whether logging or measurement has priority at these times.

Setting item	Setting value [Factory default]	Description
Logging priority	[Logging]	When there is no free capacity in the controller memory, subsequent measurement cannot be received until free capacity becomes available. All measurement target images are logged, but the measurement takt time becomes longer.
Logging priority	Measurement	Measurement will continue even if there is no free capacity in the controller memory. New logging is not performed until free capacity becomes available in the controller memory. The measurement takt time is maintained, but some measurement may not be logged.

Set the data logging conditions.

The data format is set with the processing item "Data Logging".

Setting item	Setting value [Factory default]	Description
Data Logging	[None]	Measurement data is not saved.
	Only NG	Measurement data is saved when an NG error occurs in a unit before "Data Logging". If an NG error occurs after the "Data Logging" processing unit, data logging is not performed.
	All	All measurement data is saved.

Set the logging data save destination.

Setting item	Setting value [Factory default]	Description
Folder name	[RAMDisk] USBDisk	The data is saved in the specified destination folder (RAMDisk or USBDisk). Set the file name with the processing unit [Data Logging].

About loading data to a PC

Factory settings are set so that logging data is saved in the controller RAMDisk.
When logging data is loaded to a PC, set USBDisk as the save destination.
Logging data is first saved to the controller RAMDisk and then can be copied from the RAMDisk and saved to the USBDisk using "Copy files" in "Save to file".

Tap [OK].
Settings are confirmed and the Logging Setting window closes.

Important

Logging images saved in the controller memory are overwritten starting with the oldest image if the upper limit for the number of save images is exceeded.
About Number of Logging Images
The data saved in the controller memory or RAMDisk is deleted when the controller is restarted.

About image logging

When the number of files in the save destination folder increases, the time needed for image saving increases.
If "Camera Image Input" is used several times in a flow, the image from the last "Camera Image Input" is saved.
If image transfer is disabled using the camera selection setting for the [Camera Image Input] unit, black images are saved instead of images from the disabled camera.

About number of images that can be saved

This will vary depending on the size of the images and the resolution of the connected camera.
The number of images that can be saved on the RAMDisk or USBDisk depends on free capacity.
- If RAMDisk is selected, this depends on the controller memory capacity.
- If USBDisk is selected, this depends on the USBDisk capacity.
The following methods can be used to increase the number of images that can be saved on the RAMDisk or USBDisk.
- Shorten file names when saving directly under the root directory.
  When saving image files directly under the root directory, the number of images that can be saved is about 126 due to FAT file format limitations. If file names are shortened, this can be increased to a maximum of 512. (FZ3-9/H9 models have no limit, because they use the NTFS format.)
- Saving in a subfolder
  When saving in sub-folders (\USBDisk\SUB, etc.) and not in the root directory, a maximum of 999 images can be saved in each folder. (FZ3-9/H9 models have no limit, because they use the NTFS format.)
