LonTalk Interface Developer Errors (LID)

Overview

The LID error messages described in this chapter do not necessarily include the

same wording that is shown at runtime. Instead, this chapter provides a
summary of the message’s meaning for each message, followed by a brief

discussion of possible reasons and remedies. In all cases, be sure to consult the

actual message reported by the utility at runtime, because the actual message is
likely to contain additional details (for example, the name of the specific file for

which the message is issued, or more details about the precise failure reason).
A numbering convention is used to identify the LID error messages as errors (1-
3999), warnings (4000-7999), or hint codes (8000-9999). Not all messages are

displayed in all contexts, but the numerical message identifier is always unique
and unambiguous.

LID Errors

Table 6 lists the LID error codes.

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. Verify that

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. Verify that
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.

5

An error occurred when reading a device interface file

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.
