3.10 ERROR CODES

There are four types of errors flagged by the
CR10: Compile, Run Time, Editor, and *D
Mode. Compile errors are errors in
programming which are detected once the
program is entered and compiled for the first
time (*0, *6, or *B Mode entered). If a
programming error is detected during
compilation, an E is displayed with the 2 digit
error code. The Instruction Location Number of
the Instruction which caused the error is
displayed to the right of the error code (e.g.,
105 indicates that the fifth instruction in Table 1
caused the error). Error 22, missing END, will
indicate the location of the instruction which the
compiler cannot match with the END
instruction.
Run time errors are detected while the program
is running. The number of the instruction being
executed at the time the error is detected is
displayed to the right of the error code (e.g.,
E09 06 indicates that an Instruction 6 in the
program is attempting to store data in input
locations beyond those allocated). Run time
errors 9 and 31 are the result of programming
errors. While error 8 will display the number of
the instruction that was being executed when
the error occurred, it is unlikely that the
instruction has anything to do with the error.

If there is a run time error in a table with a fast
execution interval, the error may be written to
the display so frequently that it seems the
CR10 is not responding to the keyboard. Once
the program is stopped, normal function will
return. To stop the program some entry must
be changed which requires recompiling
(Section 1.1.4). For example, enter 0 for the
execution interval of Table 1 (i.e., enter *1A0A
as fast as possible).
Error 8 is the result of a hardware and software
"watchdog" that checks the processor state,
software timers, and program related counters.
The watchdog will attempt to reset the
processor and program execution if it finds that
the processor has bombed or is neglecting
standard system updates, or if the counters are
out of allowable limits. Error code 08 is flagged
when the watchdog performs this reset. E08 is
occasionally caused by voltage surges or
transients. Frequent repetitions of E08 are
indicative of a hardware problem or a software
bug and should be reported to Campbell
Scientific. The CR10 keeps track of the
number of times (up to 99) that E08 has
occurred. The number can be displayed and
reset in the *B Mode (Section 1.6) or with the
Telecommunications A command (Section 5.1).
Editor errors are detected as soon as an
incorrect value is entered and are displayed
immediately. Only the error code is displayed.
