3.10 ERROR CODES

There are four types of errors flagged by the

CR510: 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., E23 105; 105

indicates that the fifth instruction in Table 1 caused

error 23). Error 22, missing END, will indicate the

location of the instruction which the compiler

cannot match with an 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 E08 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

CR510 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). The program can easily be

stopped by pressing any key while the CR10KD

is displaying “HELLO” after applying power (turn

the CR510 off and then on again). This delays

program execution for about two minutes,

allowing the program to be changed.

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 CR510 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).

Error 10 is displayed if the primary power drops

below 9.6 volts. When this happens, the

CR510 stops executing programs. The low

voltage counter (∗B Window 9, Section 1.6)

counts the number of times the voltage drops

below 9.6 volts and displays a double dash (--) if

the CR510 is currently in a low voltage shut

down. Below approximately 8.5 volts the

CR510 will not communicate with the CR10KD

or modem, although there may be enough

power to display characters on the CR10KD.

Editor errors are detected as soon as an

incorrect value is entered and are displayed

immediately. Only the error code is displayed.

∗D Mode errors indicate problems with saving

or loading a program. Only the error code is

displayed.
