Program Error Information
FAL/FALS Error Information
Name Address Description Access Updated
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
Read-only
Name Address Description Access Updated
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.)
