Mitsubishi Electric FX5 485 BD F.A.Q.

How can I connect the FX5-485-BD to a Mitsubishi FX5U PLC?

To connect the FX5-485-BD to a Mitsubishi FX5U PLC, first ensure that the PLC is powered off. Attach the FX5-485-BD board to the left side of the FX5U by aligning it with the appropriate slots and securing it with screws. Once attached, power on the PLC and configure the communication parameters in the PLC programming software.

What are the steps to configure RS485 communication using GX Works3?

In GX Works3, open your project and navigate to the 'Navigation' tab. Select 'Module Parameters' under 'Parameter'. Choose the 'FX5-485-BD' module and configure the communication settings, such as baud rate, parity, and stop bits, according to your network requirements. Apply the settings and download the configuration to the PLC.

How do I troubleshoot communication issues with the FX5-485-BD?

Start by checking the physical connections and ensuring that the wiring is correct. Verify the communication parameters, such as baud rate and parity, are consistent across all devices. Use a diagnostic tool to monitor the communication signals. Update the firmware of the PLC and module if necessary.

Can the FX5-485-BD be used for Modbus communication?

Yes, the FX5-485-BD can be configured for Modbus communication. In GX Works3, set up the module parameters for Modbus mode and define the appropriate slave or master settings. Ensure that all connected devices are configured to communicate using the Modbus protocol.

What maintenance is required for the FX5-485-BD module?

Routinely check the physical connections to ensure they are secure and free from corrosion. Inspect the module for any signs of damage or wear. Keep the module and surrounding area clean and dust-free. Update the firmware periodically to maintain optimal performance.

Is it possible to use the FX5-485-BD for custom serial communication protocols?

Yes, the FX5-485-BD can be programmed for custom serial communication protocols using the PLC's instruction set. You can write a custom communication routine in GX Works3, tailoring the transmit and receive instructions to meet the protocol's requirements.

How to properly terminate an RS485 network when using the FX5-485-BD?

RS485 networks require termination resistors at each end of the communication line to prevent signal reflections. Typically, a 120-ohm resistor is used. Ensure that the FX5-485-BD is one of the terminal devices and connect a resistor between the A and B lines if it is at the end of the line.

What is the maximum cable length supported by the FX5-485-BD for RS485 communication?

The maximum cable length for RS485 communication with the FX5-485-BD is approximately 1200 meters (4000 feet). However, this can vary based on the cable quality, baud rate, and environmental conditions. It is recommended to use high-quality twisted pair cables for optimal performance.

How do I update the firmware for the FX5-485-BD module?

To update the firmware, download the latest firmware version from the Mitsubishi Electric website. Connect your computer to the PLC and use the GX Works3 software to perform the firmware update. Follow the instructions provided with the firmware file to complete the update process.

What should I do if the FX5-485-BD is not recognized by the PLC?

If the FX5-485-BD is not recognized, first power off the PLC and recheck the installation of the module to ensure it is correctly seated. Verify that the module is listed in the GX Works3 module configuration. If the issue persists, try resetting the PLC or updating the firmware.
