A402 A40213 Interrupt Task
Error Flag
(Non-fatal
error)
ON when the Detect Interrupt Task Errors setting in
the PLC Setup is set to “Detect” and one of the fol-
lowing occurs for the same Special I/O Unit.
FIORF(225), IORF(097) (CJ1-H-R CPU Units only),
IORD(222) or IOWR(223) in a cyclic task are com-
peting with FIORF(225), IORF(097), IORD(222) or
IOWR(223) in an interrupt task.
FIORF(225), IORF(097), IORD(222) or IOWR(223)
was executed in an interrupt task when I/O was being
refreshed.
If cyclic refreshing is not disabled in the PLC Setup
for a Special I/O Unit and FIORF(225), IORF(097),
IORD(222) or IOWR(223) is executed for the same
Special I/O Unit in an interrupt task, a duplicate
refreshing status will occur and an interrupt task error
will occur.

A40215 FAL Error Flag
(Non-fatal
error)
ON when a non-fatal error is generated by executing
FAL(006). 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 corresponds to the FAL
number specified in FALS(006) will be turned ON
and the corresponding error code will be written to
A400. Error codes 4101 to 42FF correspond to FAL
numbers 001 to 2FF (0 to 511).
1: FALS(006) error occurred
0: FALS(006) not executed
(This flag will be turned OFF when the error is
cleared.)

Memory Error
Location
When a memory error occurs, the Memory Error Flag
(A40115) is turned ON and one of the following flags
is turned ON to indicate the memory area where the
error occurred
A40300: User program
A40304: PLC Setup
A40305: Registered I/O Table
A40307: Routing Table
A40308: CPU Bus Unit Settings
When a memory error occurs, the CPU Unit will con-
tinue operating and the ERR/ALM indicator on the
front of the CPU Unit will flash.
1: Error
0: No error
(The corresponding flag will be turned OFF when the
error is cleared.)
Cleared Cleared A40115
A40309 Memory Card
Start-up
Transfer Error
Flag
ON when automatic transfer at start-up has been
selected and an error occurs during automatic trans-
fer. An error will occur if there is a transfer error, the
specified file does not exist, or the Memory Card is
not installed.
1: Error
0: No error
(This flag will be turned OFF when the error is
cleared by turning the power off. The error cannot be
cleared without turning the power off.)
Cleared Cleared Refreshed when power
is turned ON.
A40310 Flash Mem-
ory Error Flag
ON when the flash memory is physically destroyed.
1: Error
0: No error
Cleared Cleared Refreshed when error
is detected.
