Crash Codes
This chapter lists the 4010 FACP's "crash codes." A crash code indicates that
an unrecoverable error (a crash) has occurred to the software executing on the
4010 FACP.
The exact troubleshooting information that you can gather from a crash depends
on whether you are at the panel at the time of the crash.
•
If You Are at the Panel When a Crash Occurs. Within 45 Seconds of a
crash, the LCD clears, the LEDs flash, the piezo sounds, and a crash
message displays for 45 seconds. After 45 seconds, the system attempts to
reset itself and the crash information is cleared from the display.
The crash message appears similar to the following. Make sure to record
all information, including program counter, bank number, and task number.
CRASH # xx
PC = xxxx
Crash # xx is a hexadecimal code corresponding to a specific unrecoverable
error. Refer to Table 3-1 for a list of these codes and possible corrective
actions.
PC = xxxx is the hexadecimal address of the CPU's program counter.
BANK # xx is the hexadecimal address of the active memory bank at the
time of the crash.
TASK xx is the active task number (in hexadecimal) at the time of the crash.
•
If You Are Not at the Panel When a Crash Occurs. The Crash Code and
the Task Number (see above for descriptions) are stored in a historical log
entry.
