All
Error code
When a non-fatal error (user-defined
FAL(006) or system error) or a fatal
error (user-defined FALS(007) or
system error) occurs, the 4-digit
hexadecimal error code is written to
this word. When two or more errors
occur simultaneously, the highest
error code will be recorded.

Other Fatal
Error Flag
ON when a fatal error that is not
defined for A401.01 to A401.15
occurs. Detailed information is output
to the bits of A314.
There are no errors that affect this
flag at this time. This flag is reserved

FALS Error
Flag
(fatal error)
ON when a fatal error is generated
by the FALS(007) instruction. The
CPU Unit will stop operating and the
ERR/ALM indicator will light.
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.

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 indicator on the
front of the CPU Unit will light.
This flag will be turned OFF when
the error is cleared.

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 A295.08 to
A295.15. Refer to the description of
A295 for more details on program
errors.
This flag will be turned OFF when
the error is cleared.
