Error Processing Section 11-2
Errors are listed in order of importance. When two or more errors occur at the
same time, the more serious error’s error code will be recorded in A400.

The error code in A400 will
indicate the FAL number.
The leftmost digit of the code
will be 4 and the rightmost 3
digits of the code will be
from 100 to 2FF hex and will
correspond to FAL numbers
001 to 511.
Correct according to cause indicated by
FAL number (set by user).

ON when the Detect Inter-

the PLC Setup is set to
“Detect” and one of the fol-

Special I/O Unit.
IORF(097), FIORF(225)
(CJ1-H-R CPU Units only),
IORD(222) or IOWR(223) in
a cyclic task are competing
with FIORF(225),
IORF(097), IORD(222) or
IOWR(223) in an interrupt
task.
IORF(097), FIORF(225)
(CJ1-H-R CPU Units only),
IORD(222) or IOWR(223)
was executed in an interrupt
task when I/O was being
refreshed.
Note If cyclic refreshing is
not disabled in the
PLC Setup for a Spe-
cial I/O Unit and
IORF(097),
FIORF(225)
(CJ1-H-R CPU Units
only), IORD(222) or
IOWR(223) is exe-
cuted for the same
Special I/O Unit in an
interrupt task, a dupli-
cate refreshing status
will occur and an inter-
rupt task error will
occur.
Check the program. Either disable
detection of interrupt task errors in the
PLC Setup (address 128, bit 14) or cor-
rect the problem in the program.
