Updating the firmware of a Mitsubishi FX5U PLC involves a series of steps to ensure the process is carried out smoothly and without any errors. Here's a general guide on how to update the firmware of a Mitsubishi FX5U PLC:
Important Note: Firmware updates should be performed with
caution, as improper procedures can lead to PLC malfunctions. Ensure you have a
backup of your PLC programs and settings before proceeding.
1. Check Compatibility and Download Firmware:
- Visit the
official Mitsubishi Electric website or your local Mitsubishi distributor to
find the latest firmware version compatible with your FX5U PLC model.
- Download the
firmware file to your computer.
2. Install GX Works3 Software:
- If you haven't
already, install the GX Works3 programming software on your computer. This
software is used to update the firmware of Mitsubishi PLCs.
3. Prepare Communication Setup:
- Connect your FX5U
PLC to your computer using the appropriate programming cable (USB or Ethernet).
- Open GX Works3
and create a new project or open an existing project associated with the PLC.
4. Access the PLC Management:
- In the project
workspace, find and click on the PLC Management button or option. This should
be located in the project explorer or toolbar.
5. Select the Firmware Update Tool:
- In the PLC
Management window, locate the option to update the firmware. It might be named
"Firmware Update Tool" or something similar.
6. Load the Firmware File:
- Use the Firmware
Update Tool to load the firmware file you downloaded in Step 1.
7. Connect to the PLC:
- Follow the
on-screen instructions to connect to your FX5U PLC. This might involve
selecting the appropriate communication interface (USB or Ethernet) and
specifying the PLC's IP address or COM port.
8. Perform the Firmware Update:
- Once the
connection is established, follow the prompts to perform the firmware update.
The process might take a few minutes.
- Do not interrupt
power to the PLC or disconnect the communication cable during the update
process.
9. Verify and Restart:
- After the update
is complete, the software should display a confirmation message.
- Disconnect and
reconnect the PLC's power supply to ensure the new firmware is applied.
10. Test and Verify:
- After updating
the firmware, test your PLC to ensure it's functioning as expected. Load your
existing program onto the PLC and confirm that it operates correctly.
11. Backup Programs and Settings:
- It's a good
practice to backup your PLC programs and settings after the firmware update,
especially if you made changes to the program or parameters.
Remember that the exact steps may vary depending on the version
of GX Works3 software and the specific firmware update tool provided by
Mitsubishi Electric. Always refer to the official documentation and manuals
provided by Mitsubishi for accurate and up-to-date instructions. If you're not
comfortable with performing firmware updates, consider seeking assistance from
a certified Mitsubishi distributor or technician.
