A401 A40106 FALS Error
Flag
(Fatal error)
ON when a non-fatal error is generated by the
FALS(006) instruction. The CPU Unit will continue
operating and the ERR/ALM indicator will flash.
The corresponding error code will be written to A400.
Error codes C101 to C2FF correspond to FALS num-
bers 001 to 511.
1: FALS(006) executed
0: FALS(006) not executed
This flag will be turned OFF when the FALS errors
are cleared.
Cleared Cleared Refreshed when error
occurs.
A400
A40108 Cycle Time
Too Long Flag
(Fatal error)
ON if the cycle time exceeds the maximum cycle time
set in the PLC Setup (the cycle time monitoring time).
CPU Unit operation will stop and the ERR/ALM indi-
cator on the front of the CPU Unit will light.
0: Cycle time under max.
1: Cycle time over max.
This flag will be turned OFF when the error is
cleared.
Cleared Cleared Refreshed when the
cycle time exceeds
maximum.
PLC Setup (Cycle time
monitoring time)
A40109 Program Error
Flag
(Fatal error)
ON when program contents are incorrect.
CPU Unit operation will stop and the ERR/ALM indi-
cator on the front of the CPU Unit will light. The task
number where the error occurred will be stored in
A294 and the program address will be stored in A298
and A299.
The type of program error that occurred will be stored
in bits 8 to 15 of A295. Refer to the description of
A295 for more details on program errors.
1: Error
0: No error
This flag will be turned OFF when the error is
cleared.
Cleared Cleared A294,
A295,
A298 and A299
A40110 I/O Setting
Error Flag
(Fatal error)
ON when a the registered I/O tables do not match the
actual I/O tables (i.e., the Units actually installed in
the PLC) or, for a CJ1-H CPU Unit, when an Interrupt
Input Unit is connected in the wrong position (not slot
0 to 4, i.e., the 5 slots to the right of the CPU Unit).
CPU Unit operation will stop and the ERR/ALM indi-
cator on the front of the CPU Unit will light.
1: Error
0: No error
This flag will be turned OFF when the error is
cleared.
Cleared Cleared A40508
A40111 Too Many I/O
Points Flag
(Fatal error)
ON when the number of I/O points being used in
Basic I/O Units exceeds the maximum allowed for the
PLC or when there are more than 11 Units con-
nected in one Rack.
CPU Unit operation will stop and the ERR/ALM indi-
cator on the front of the CPU Unit will light.
1: Error
0: No error
This flag will be turned OFF when the error is
cleared.
