A402 10 PLC Setup Error Flag
(non-fatal error)
ON when there is a setting error in the
PLC Setup. The CPU Unit will continue
operating and the ERR/ALM indicator
on the front of the CPU Unit will flash.
Note This flag will be turned OFF when
the error is cleared.
ON: Error
OFF: No error
Cleared Cleared Refreshed

occurs.
15 FAL Error Flag
(non-fatal error)
ON when a non-fatal error is generated
by executing FAL. The CPU Unit will
continue operating and the ERR/ALM
indicator on the front of the CPU Unit
will flash.
The bit in A360 to A391 that corre-
sponds to the FAL number specified in
FALS will be turned ON and the corre-
sponding error code will be written to
A400. Error codes 4101 to 42FF corre-
spond to FAL numbers 001 to 2FF (0 to
511).
Note This flag will be turned OFF when
the error is cleared.

occurred
OFF: FAL not exe-
cuted

Memory Error Location When a memory error occurs, the
Memory Error Flag (A401.15) is turned
ON and one of the following flags is
turned ON to indicate the memory area
where the error occurred
A403.00: Ladder program
A403.04: PLC Setup
When a memory error occurs, the CPU
Unit will continue operating and the
ERR/ALM indicator on the front of the
CPU Unit will flash.
Note The corresponding flag will be
turned OFF when the error is
cleared.
ON: Error
OFF: No error
Cleared Cleared Refreshed

memory is physically destroyed.
ON: Error
OFF: No error

when error is
detected.
A404 I/O Bus Error Details Contains information on I/O bus errors.
The CPU Unit will stop operating and
the ERR/ALM indicator on the front of
the CPU Unit will light.
Note A401.14 (I/O Bus Error Flag) will
turn ON.
