10.3.1.1 CompileResults
Reports messages generated by the CR800 at program upload and compile-time.
A message will report that the program compiled OK, provide warnings about
possible problems, or indicate there are run-time errors. Error messages may not
be obvious because the display column is too short. Messages report variables that
caused out-of-bounds conditions, watchdog information, and memory errors.
Messages may be tagged onto this line as the program runs.
Warning messages are issued by the CRBasic compiler to advise that some
expected feature may not work. Warnings are different from error messages in
that the program will still operate when a warning condition is identified.
A rare error is indicated by "mem3 fail" type messages. These messages can be
caused by random internal memory corruption. When seen on a regular basis with
a given program, an operating system error is indicated. "Mem3 fail" messages
are not caused by user error, and only rarely by a hardware fault. Report any
occurrence of this error to a Campbell Scientific applications engineer, especially
if the problem is reproducible. Any program generating these errors is unlikely to
be running correctly.
Examples of some of the more common warning messages are listed in table
Warning Message Examples
(p. 404).
Table 106. Warning Message Examples
Example of Warning Message Meaning
CPU:DEFAULT.CR1 -- Compiled in
PipelineMode.
Error(s) in CPU:NewProg.CR1:
line 13: Undeclared variable Battvolt.
A new program sent to the datalogger failed to
compile, and the datalogger reverted to running
DEFAULT.cr8.
Warning: Cannot open include file CPU:
Filename.cr8
The filename in the Include instruction does not
match any file found on the specified drive.
Since it was not found, the portion of code
referenced by Include will not be executed.
Warning: Cannot open voice.txt
voice.txt, a file required for use with a COM310
voice phone modem, was not found on the CPU:
drive.
Warning: COM310 word list cannot be a
variable.
The Phrases parameter of the VoicePhrases()
instruction was assigned a variable name instead
of the required string of comma-separated words
from the Voice.TXT file.
Warning: EndIf never reached at runtime.
Program will never execute the EndIf
instruction. In this case, the cause is a Scan()
with a Count parameter of 0, which creates an
infinite loop within the program logic.
Warning: Internal Data Storage Memory
was re-initialized.
Sending a new program has caused the final-
storage memory to be re-allocated. Previous
data are no longer accessible.
Warning: Machine self-calibration failed.
Indicates a problem with the analog
measurement hardware during the self
