How to resolve CRC/LRC error on Mitsubishi FX3U?
To resolve a CRC/LRC error, check the Communication Format, Turn Around Delay, and Message to Message Delay data registers for errors; D8400 and D8410-D8411, or D8420 and D8430-D8431.
What causes communication timeout after retries failed on Mitsubishi Controller?
A communication timeout after retries failed can occur if the Slave Node Address and communication parameters are not set up correctly. Verify that these settings are accurate.
How to fix invalid device address in Mitsubishi FX3U?
To resolve an invalid device address error, verify that the MODBUS Device Address Allocation of the Slave is set correctly. Ensure master data is in a valid range for a selected command. Confirm that the master is accessing valid device ranges.
What to do if communication will not function correctly due to insecure connection of Mitsubishi FX3U Controller?
If communication is not functioning correctly due to an insecure connection, verify that the communication equipment is securely connected with the PLC.
How to fix communication if it will not function correctly due to incorrect wiring of Mitsubishi FX3U Controller?
To resolve communication issues caused by incorrect wiring, verify that all communication equipment is correctly wired.
What to do if Mitsubishi Controller data is received but not sent?
If data is received but not sent, check the status of the "RD" and "SD" indicator LEDs provided in the optional equipment. It's also important to verify the wiring, communication settings, and error statuses of the master and slave stations.
What to do if Mitsubishi FX3U Controller data is sent but not received?
If data is being sent but not received, check the status of the "RD" and "SD" indicator LEDs provided in the optional equipment. Additionally, verify the wiring, communication settings, and error statuses of the master and slave stations.
