Other Fatal Error Flag
A401.00
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.
OFF: No other fatal error
ON: Other fatal error
Program Error Flag
(fatal error)
A401.09
ON when program contents are incorrect.
CPU Unit operation will stop.
Read-only
When error
occurs
Program Error Task
A294
This word contains the task number of the task that was
being executed when program execution was stopped
because of a program error.
Read-only
Instruction Processing Error
Flag
A295.08
This flag and the Error Flag (ER) will be turned ON when
an instruction processing error has occurred and the
PLC Setup has been set to stop operation for an instruc-
tion error.
Read-only
Indirect DM/EM BCD Error
Flag
A295.09
This flag and the Access Error Flag (AER) will be turned
ON when an indirect DM BCD error has occurred and the
PLC Setup has been set to stop operation an indirect DM
BCD error. (This error occurs when the content of an
indirectly addressed DM word is not BCD although BCD
mode has been selected.)
Read-only
Illegal Access Error Flag
A295.10
This flag and the Access Error Flag (AER) will be turned
ON when an illegal access error has occurred and the
PLC Setup has been set to stop operation an illegal
access error. (This error occurs when a region of mem-
ory is accessed illegally.)
Read-only
No END Error Flag
A295.11
ON when there isn’t an END(001) instruction in each pro-
gram within a task
Read-only
Task Error Flag
A295.12
ON when a task error has occurred. The following condi-
tions generate a task error.
There isn’t even one regular task that is executable
(started).
There isn’t a program allocated to the task.
Read-only
Differentiation Overflow
Error Flag
A295.13
ON when the allowed value for Differentiation Flags
which correspond to differentiation instructions has been
exceeded.
Read-only
Illegal Instruction Error Flag
A295.14
ON when a program that cannot be executed has been
stored.
Read-only
UM Overflow Error Flag
A295.15
ON when the last address in UM (User Memory) has
been exceeded
Read-only
Program Address Where
Program Stopped
A298 and
A299
These words contain the 8-digit binary program address
of the instruction where program execution was stopped
due to a program error.
A298: Rightmost 4 digits, A299: Leftmost 4 digits

FAL Error Flag
(non-fatal error)
A402.15
ON when a non-fatal error is generated by executing
FAL(006). The CPU Unit will continue operating.
Read-only
Executed FAL Number
Flags
A360 to
A391
The flag corresponding to the specified FAL number will
be turned ON when FAL(006) is executed. Bits A360.01
to A391.15 correspond to FAL numbers 001 to 511.
Read-only
FALS Error Flag
(fatal error)
A401.06
ON when a fatal error is generated by the FALS(006)
instruction. The CPU Unit will stop operating.
Read-only
FAL/FALS Number for Sys-
tem Error Simulation
A529
Set a dummy FAL/FALS number to use to simulate the
system error using FAL(006) or FALS(007).
Set the FAL/FALS number.
0001 to 01FF hex: FAL/FALS numbers 1 to 511
0000 or 0200 to FFFF hex: No FAL/FALS number for sys-
tem error simulation. (No error will be generated.)
