LonTalk Interface Developer Utility Error and
Warning Messages
Introduction
All messages, errors, and warnings, come with a standard Echelon message
identifier LID#zzz, where zzz is a unique decimal number.
All messages shown below are not actually given with the precise language
shown at runtime. Instead, a summary of the message meaning is given for each
message, followed by a brief discussion of possible reasons and remedies. In all
cases, make sure to consult the actual message as produced by the tool at
runtime, as the actual message is likely to contain more details (for example, the
name of the offending file, or more detailed language about the precise failure
reason).
See the Neuron Tools Errors Guide for information about errors issued by the
Neuron C compiler (warning and error messages with NCC#zzz identifiers).
Error Messages
LID# Description
1 An NV, CP, or MT item was expected but not present – internal error
Remove the device interface files (.xif and .xfb extension), and re-run
the LonTalk Interface Developer utility to see if the problem persists.
Use the Trace verbosity level to help track down the problem.
2 A file cannot be opened for read access
See the error message received for details of the offending file. Make
sure the file is available and readable and the path is accessible.
3 A file cannot be opened for write access
See the error message received for details of the offending file. Make
sure the file is available and writable and the path is accessible.
4 A property value is required but has not been obtained from any data
source
This is an internal error, probably a result of an earlier failure. A
non-fatal error during the creation of the device interface file might
lead to this error. Re-run the LonTalk Interface Developer utility in
Trace verbosity mode and carefully examine the LonTalk Interface
Developer utility Summary window to determine the root cause of
the failure
