Logging Measurement Values and Measurement Images

Logging is a function for saving camera input images or measurement results when executing measurement.
There are two different logging methods.
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.
  1. On the Main screen, tap [Measure] - [Save last logging image].
    The Logging Setting window is displayed.
    Save last logging image
  2. Set the logging images save destination.
    Specify the image file save destination (RAMDisk or USB memory).
  3. Edit the file name as required.
    Save last logging image
  4. Tap [OK].
    Save last logging image
    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.
  1. On the Main screen, tap the [Measure] menu - [Logging setting].
    The Logging Setting window is displayed.
  2. Set the logging conditions for images.
    Logging Setting window
    Setting item
    Set 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.
  3. Set the logging images save destination.
    Logging Setting window
    Note
    • 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.

      Also, the controller memory is cleared if the power is turned off.
      To keep images, select "Save to memory + file" and save images to USB memory, etc.
    Setting item
    Set value
    [Factory default]
    Description
    Save destination
    [Save to memory]
    Saves to the controller memory.
    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
    Set 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
    －
    Set 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
    Save 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 error image save destination:
      \USBDisk\S000-002\NG\image_(Measurement ID).IFZ
  4. 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 tact time is short, time lag may occur with writing from the controller memory to the RAMDisk or USBDisk and temporary absences of free space in the controller memory may occur.Select whether logging or measurement has priority at these times.
    Logging Setting window
    Setting item
    Set 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 tact time becomes longer.
    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 tact time is maintained, but some measurement may not be logged.
  5. Set the data logging conditions.
    The data format is set with the processing item "Data Logging".
    Logging Setting window
    Setting item
    Set 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.
  6. Set the logging data save destination.
    Logging Setting window
    Setting item
    Set 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].
    Note
    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".
  7. Tap [OK].
    Logging Setting window
    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.
Note
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.
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.
    • Save in sub-folders
      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.
