generated XIF file with any Echelon or third-party LNS tool, including the
LonMaker Integration Tool.
If output redirection is in effect, the current output file is closed before creating
the XIF file.
Y – Download Neuron Executable
Use this command to download a Neuron application image file to the selected
device. You can specify an application image file (.ndl or .nxe extension) that is
generated by the NodeBuilder FX Development Tool or Mini FX application. If
the device already contains an alphanumeric application ID, this name is the
default for the application image file name.
Recommendation: Use a .ndl file for downloading the device application. A .ndl
file contains the application code and initial values for configuration network
variables, whereas a .nxe file contains the application code only.
If the download is successful, you are asked if you want to set the device
configured, online. Answer “yes” to this question only if the device already
contains a valid network configuration for this application. By default, the device
will be set to the unconfigured state. After setting the state, NodeUtil reads the
state of the device and displays any errors.
For .nxe files, the Y command does not check that the application image file that
you are loading is compatible with the device hardware configuration. The Y
command does perform compatibility checking for .ndl files. Thus, before loading
an application to a device using a .nxe file, verify that the application image file
was linked using the correct device model and firmware version for your target
device. For FT 3150 or PL 3150 devices, also verify that the application image
file was linked using the correct memory map for the device.
If an incompatible application image file is loaded to a device, the device
generally performs continuous watchdog resets. You might be able to recover it
by downloading a compatible application image file. However:
• If the device is based on an FT 3120, PL 3120, or PL 3170 Smart
Transceiver, it might not be recoverable.
• If it is based on an FT 3150 or PL 3150 Smart Transceiver, you can use
the EEBLANK program (available from the Echelon Web site) to blank
the EEPROM and reboot the default image.
• If it is based on an FT 5000 Smart Transceiver or Neuron 5000 Processor,
you might be able to recover it by clearing the external non-volatile
memory for the device. See the
Series 5000 Chip Data Book
for a
description of how to clear the external non-volatile memory.
If you attempt to set the device to the configured state after loading, but the
device does not contain a valid network configuration for this application, then
the Neuron firmware detects a configuration checksum error and sets the device
to be unconfigured.
