Response
to Major Faults (W ord 11 of the Status File)
This bit: Indicates this fault: And the fault is:
00 Corrupted program file
01 Corrupted address in ladder program (see fault codes 1019)
02 Programming error (see fault codes 2029)
Recoverable
hfl i
05 Startup protection fault (see word 26, bit 1)
Processor sets bit 5; if your fault routine does not reset this bit,
the processor inhibits startup
the fault routine
can instruct the
processor to clear
the fault and then
07 Usergenerated fault; processor jumped to fault routine
(see fault codes 09)
the fault and then
resume scanning
the program.
08 Watchdog faulted
pg
13 STI file does not contain ladder logic or does not exist
03 Processor detected an SFC fault (see fault codes 7479)
04 Processor detected an error when assembling a ladder
program file (see fault code 70)
Notrecoverable
09 System is configured wrong; you installed a RAM cartridge but
configured the system for an EEPROM or you violated 32point
I/O module placement rules for 1slot addressing
Not recoverable
the processor
enters fault mode
without scanning
10 Nonrecoverable hardware error
without scanning
the fault routine.
14 Fault routine does not contain ladder logic or does not exist
15 Fault routine program file does not contain ladder logic
A remote block transfer from a fault routine causes the processor to stop
scanning all programs until the block transfer completes.
Major Fault Codes
Table 7.H lists major fault codes. The processor stores the fault code in
word 12 of the processor status file.
