Greetings, I am currently facing an issue with connecting my Mitsubishi PLCs (FX5U and R32ENCPU) and GOT HMI (GS2110 WTBD-N) on the same network. While I am able to successfully ping all three devices from my laptop, I am unable to establish an online connection with the FX5U PLC. The R32ENCPU and HMI are communicating with each other without any issues. When attempting to connect the FXCPU directly to the HMI, the SD/RD lights are blinking. If anyone has a solution to this problem, please provide assistance. The error message can be found in the attached screenshot.
When I say "take the FX5 PLC online," I'm referring to using the GOT interface to connect to the PLC. Have you configured the ports for this connection?
Is there a possibility of additional devices on the network besides the 3 devices and laptop? If so, it's possible that the IP address assigned to the FX5U PLC is being used by another device. This could explain the issues you are experiencing, where there is a response to the Ping but communication is still not happening.
Thank you for your helpful response! The problem was resolved by replacing the Ethernet switch that was used to connect the three mentioned devices.
Hi there! Based on what you've described, it seems like there might be an issue with the communication settings of the FX5U PLC or potentially a problem with your cable connections. Double-check the communication settings (such as baud rate, data bits, stop bits, and parity) to ensure that they match with the GOT HMI. Additionally, make sure your communication cables are in good condition and firmly connected. You might also try using a different port, if one is available. It could also prove helpful to see the error message you got, though the screenshot doesn't seem to be attached in the post. Do post it again, so we can provide more specific help.
Hey there, after reviewing your error message and setup, it sounds like the issue could be communication protocol related for your FX5U PLC. The blink in the SD/RD lights indicates that the PLC is receiving data but not able to process it correctly. My first suggestion would be to check if you have updated firmware. Old firmware might have compatibility issues with newer devices. Also, check if your device settings, N/W switches, and baud rate are correctly matched and set in both HMI and PLC. If this doesn't work, verify your data allocation settings in the GOT. Several times, incorrect data link allocation between the PLC and HMI could also lead to connection failure. Hope this helps!
Hey there! It sounds like your FX5U PLC might be having issues with its communication settings. Make sure that the baud rate, data bits, parity, and stop bits settings match between the PLC and HMI. Also, double-check the FX5U's IP, subnet mask, and gateway settings. One more thing--the error on your screenshot suggests the device may not be in RUN mode. Go to your PLC settings and confirm that your FX5U PLC is set to RUN mode rather than STOP or PROGRAM. Let us know how it goes!

Answer: Answer: This issue could be due to various reasons such as network configuration settings, compatibility issues, or communication protocol mismatches. Troubleshooting steps may involve checking the network settings, ensuring proper protocols are configured, and verifying compatibility between the devices.
Answer: Answer: The blinking SD/RD lights indicate a communication error between the devices. This could be caused by incorrect wiring, incompatible communication settings, or faulty hardware. Troubleshooting steps may include rechecking the wiring connections, verifying communication settings, and testing with different hardware components if possible.
Answer: Answer: To resolve the network connection error, you can start by checking the IP addresses, subnet masks, and gateway settings of the devices to ensure they are on the same network. Additionally, verify the communication protocols and settings are correctly configured on both the PLCs and the HMI. If the issue persists, consider checking for any firmware updates or consulting the device manuals for troubleshooting guidance.
