A400 All Error code When a non-fatal error (user-
defined FALS(006) or system
error) or a fatal error (user-
defined FALS(007) or system
error) occurs, the 4-digit hexa-
decimal error code is written to
this word. When two or more
errors occur simultaneously, the
highest error code will be re-
corded.
Refer to the CS/CJ Series Op-
eration Manual for details on
error codes.
Error code Same as
CS/CJ-series
PLC.
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 numbers 001 to 511.
This flag will be turned OFF
when the FALS errors are
cleared.
1:
FALS(006)
executed
0:
FALS(006)
not exe-
cuted
Same as
CS/CJ-series
PLC.
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 moni-
toring time). CPU Unit operation
will stop and the ERR/ALM indi-
cator on the front of the CPU Unit
will light.
This flag will be turned OFF
when the error is cleared.
0: Cycle
time under
max.
1: Cycle
time over
max.
Same as
CS/CJ-series
PLC.
A401
A40109 Program
Error Flag
(Fatal error)
ON when program contents are
incorrect.
CPU Unit operation will stop and
the ERR/ALM indicator 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.
This flag will be turned OFF
when the error is cleared.
1: Error
0: No error
Same as
CS/CJ-series
PLC.
