9. Troubleshooting
If any malfunction occurs, refer to the following items after checking the power supply to the master
and the slave.
• Problem: Communication failure
The connection or wiring of the communication cable is not secure.
Burnout or imperfect contact on the communication cable and the connector.
Communication speed of the slave does not coincide with that of the master.
The data bit, parity and stop bit of the master do not accord with those of the slave.
The instrument number of the slave does not coincide with that of the command.
The instrument numbers are duplicated in multiple slaves.
When communicating without using communication converter, make sure that the program is
appropriate for the transmission timing.
• Problem: Although communication is occurring, the response is 'exception code'.
Check whether a non-existent command code has been sent or not.
The setting command data exceeds the setting range of the slave.
The controller cannot be set when functions such as AT is performed.
While in setting mode and inputting settings via the front keypad.
