Below is a detailed guide on how to configure the FX5U PLC to use an SD card for saving and loading programs, ensuring seamless operation across multiple devices.

Step-by-Step Guide to Save and Load Programs Using an SD Card

Step 1: Access the PLC Program in GX Works 3

First, open the GX Works 3 programming tool, which is used to configure and manage Mitsubishi PLCs. In the tool, access the FX5U PLC program.

Step 2: Navigate to the Memory Card Parameters

Next, go to the "Parameter" section within the software. Here, you'll find the option labeled "Module Parameter." Click on this to open a menu of further options.

From the module parameter options, select "Memory Card Parameter." This section allows you to manage settings related to the SD card and its use within the PLC.

Step 3: Configure Boot Settings

After selecting "Memory Card Parameter," a new window will appear with various settings. Look for the "Boot Setting" section.

Under "Boot Setting," locate the item titled "Operation Setting at CPU Built-in Memory Boot." Set this option to "Clear" to ensure that the PLC will boot from the SD card rather than using the default internal memory.

Step 4: Configure Boot File Settings

Next, proceed to the "Boot File Setting" option and click it. A new window will open, allowing you to add boot files for the PLC to load during startup.

In this window, you will need to specify which files are necessary for the PLC program to start from the SD card. Be sure to select only the relevant boot files—remove any filenames that do not correspond to actual data.

Step 5: Select and Write Files to the SD Card

Once the necessary boot files are selected, you can click the "Select All" option to mark all files for writing.

After marking the files, proceed to write them onto the SD card. The SD card will now become a bootable memory device that contains the program required for the PLC to start up.

Step 6: Insert the SD Card and Power On the PLC

Take the SD card, now containing the program files, and insert it into any available slot on the FX5U PLC. Once the SD card is securely inserted, restore power to the PLC.

The PLC will automatically begin the process of transferring the program from the SD card to its internal memory, utilizing the PLC boot function to load the program.

Step 7: Remove the SD Card and Let the PLC Run

Once the program has been successfully loaded into the PLC’s internal memory, you can remove the SD card. The PLC will continue operating based on the program now stored in its memory, and no further interaction with the SD card is required.

Using an SD card for saving and loading programs in the Mitsubishi PLC FX5U provides a convenient and efficient method for managing PLC programs. By following these simple steps, you can easily transfer programs between different FX5U PLCs, ensuring quick setup and deployment for any industrial automation project. The process also provides an added layer of flexibility for program backups and updates, further enhancing the usability of the FX5U PLC system.
