Setup Troubleshooting

Symptoms and Actions

Data input or output does not operate correctly
- Run the diagnosis program to check that the device is registered and whether any initialization
errors have occurred.
- Is there a problem with the device settings, wiring, or similar? Check the I/O range setting. Also,
the input data will be undefined if the wiring terminals are not connected. Ensure that the channels
you are using are correctly connected. Connect unused channels to analog ground.
- For voltage input, check by connecting a battery or similar if you do not have any other suitable
signal source. Also check that connecting to analog ground reads correctly as 0V.
The diagnostic program works correctly but the application program does not.
The diagnostic program uses the API-TOOL functions. If the diagnostic program works correctly, other
applications should work correctly also. If you have a problem, recheck your program taking note of the
following points.
- Check the return values of the API functions.
- Refer to the source code for the sample programs.
The OS does not boot correctly or does not detect the device correctly.
Refer to the "Troubleshooting" section of API-AIO(WDM) HELP.
