Troubleshooting

Please refer to the following flowchart if a fault occurs on the fieldbus system.
Error status is reflected by the parameter settings of a fieldbus system.
When a fault occurs, please refer to the troubleshooting and the parameter setting sections of this manual,
to ensure the appropriate action is taken.
If the cause of the fault cannot be confirmed, it is possible that the equipment may have failed. When
failure of fieldbus system equipment occurs, it is possible that the error was caused by the system
