Looks like one possibility is that a device by whatever you passed in for the `deviceName` parameter does not exist or is disabled.

If you're using the new DNP3 driver, as opposed to the legacy DNP3 driver, be aware that the script function namespace is `system.dnp` and not `system.dnp3`.

Thanks for the information @Kevin.Herron .

The issue was related to the data type mismatch between the value passed to the function and the AO defined in the device. I am using Legacy dnp3 driver.
