Configuring Image Logging in FH/FHV Vision System

Image logging is a crucial function in vision systems, allowing for the storage and analysis of captured images. This guide explains how to configure image logging on the FH/FHV Series Vision System by OMRON.

1. Accessing Image Logging Settings

To set up image logging, follow these steps:

1. Open the Main Window of the vision system interface.
2. Navigate to Tool → System Settings → Other.
3. Select Logging Setting to open the configuration menu​

2. Configuring Image Logging Options

Once in the logging settings, configure the following parameters:

Image Logging Conditions

• None – No images are logged.
• Only NG (No Good) – Only images where the system detects an error are saved.
• All – All captured images are saved.

Destination for Logged Images

Select where the images should be saved:

• Save to memory – Stores images in the Controller’s RAM (temporary storage).
• Save to memory + file – Saves images in both RAM and external storage.
• Save to memory + FTP Server – Sends images to an FTP server​.

3. Advanced Image Logging Settings

Multiple Image Logging

If multiple cameras are used:

• OFF – Only the latest image per camera is saved.
• ON – All images captured during the measurement flow are saved​.

Logging Priority

If processing time is a concern, set a logging priority:

• Logging Priority Mode – Prioritizes image logging, ensuring all images are saved.
• Measurement Priority Mode – Prioritizes measurements over logging, potentially skipping some images​.

File Format Selection

Choose the format for saved images:

• IFZ – Proprietary OMRON format for FH/FHV series.
  • Stores images in high fidelity without compression artifacts.
  • Allows for re-measurement and analysis directly within OMRON’s vision system.
  • Cannot be opened directly on standard PCs, and requires OMRON tools or software (such as for viewing and processing.
• BMP (BFZ) – Standard BMP images in a container format.
  • Uncompressed, ensuring no data loss or artifacts, but resulting in large file size.
  • Can be opened on any Windows-based system without special software.
• JPG (JFZ) – JPEG images organized in folders​.
  • Uses lossy compression, reducing file size significantly. Logged images cannot be used for re-measurement and analysis due to the compression. 
  • Easily viewable on any device without special software.

4. Saving and Accessing Logged Images

Saving to External Storage

• Connect a USB drive or external HDD.
• Set the destination folder under the "Save to memory + file" option​.

Saving to FTP Server

• Configure the FTP address, username, and password.
• Set the directory where images should be stored.

Retrieving Logged Data

• You may use an FTP client or file explorer to access images stored on a USB or SD card.
• If images are in RAM disk, copy them to external storage before powering off the controller to avoid data loss

5. Best Practices for Efficient Image Logging

• Monitor storage capacity – Ensure enough space is available for image storage. 
• Optimize logging conditions – Use conditional logging (e.g., log only NG images) to reduce storage usage.
• Check system performance – Adjust task time if logging slows down measurements.

By following these steps, you can effectively configure image logging in the FH/FHV Vision System, ensuring smooth operation and data retention.
