Table 7.G
Response to Major Faults (Word 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 10Ć19)
02 Programming error (see fault codes 20Ć29) RecoverableĊ
h f l i
05 StartĆup 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 UserĆgenerated fault; processor jumped to fault routine
(see fault codes 0Ć9)
the fault and then
resume scanning
the program.
08 Watchdog faulted
p g
13 STI file does not contain ladder logic or does not exist
03 Processor detected an SFC fault (see fault codes 74Ć79)
04 Processor detected an error when assembling a ladder
program file (see fault code 70)
Not recoverable
09 System is configured wrong; you installed a RAM cartridge but
configured the system for an EEPROM or you violated 32Ćpoint
I/O module placement rules for 1Ćslot addressing
Not recoverableĊ
the processor
enters fault mode
without scanning
10 NonĆrecoverable 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.
