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
A401.09 ON when program contents are incorrect.
CPU Unit operation will stop.
A294 This word contains the task number of the task that was
being executed when program execution was stopped
because of a program error.
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.
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.)
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.)
A295.11 ON when there isn't an END(001) instruction in each pro-
gram within a task
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.
A295.13 ON when the allowed value for Differentiation Flags
which correspond to differentiation instructions has been
exceeded.
A295.14 ON when a program that cannot be executed has been
stored.
A295.15 ON when the last address in UM (User Memory) has
been exceeded
A298 and These words contain the 8-digit binary program address
A299 of the instruction where program execution was stopped
due to a program error.
A298: Rightmost 4 digits, A299: Leftmost 4 digits
Address
A402.15 ON when a non-fatal error is generated by executing
FAL(006). The CPU Unit will continue operating.
A360 to The flag corresponding to the specified FAL number will
A391 be turned ON when FAL(006) is executed. Bits A360.01
to A391.15 correspond to FAL numbers 001 to 511.
A401.06 ON when a fatal error is generated by the FALS(006)
instruction. The CPU Unit will stop operating.
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.)
