A40109
ON when program contents are incorrect.
With a Single CPU System, CPU Unit operation will stop.
With a Duplex CPU System in Duplex Mode, operation will
switch to the standby CPU Unit and operation will continue.
With a Duplex CPU System in Simplex Mode, CPU Unit
operation will stop.
A294
Provides the type and number of the tack that was being
executed when program execution stops as a result of a pro-
gram error.
A29508
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 instruction error.
A29509
This flag and the Access Error Flag (AER) will be turned ON
when an indirect DM/EM BCD error has occurred and the
PLC Setup has been set to stop operation an indirect DM/
EM BCD error.
A29510
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.
A29511
ON when there isn't an END(001) instruction in each pro-
gram within a task.
A29512
ON when a task error has occurred. The following conditions
will generate a task error.
1) There isn't an executable cyclic task.
2) There isn't a program allocated to the task.
A29513
ON when the specified Differentiation Flag Number exceeds
the allowed value.
A29514
ON when a program that cannot be executed has been
stored.
A29515
ON when the last address in UM (user program memory)
has been exceeded.
A298 and
These words contain the 8-digit hexadecimal program
A299
address of the instruction where program execution was
stopped due to a program error.
(A299 contains the leftmost digits.)

A100 to
When an error has occurred, the error code, error contents,
A199
and error's time and date are stored in the Error Log Area.
A300
When an error occurs, the Error Log Pointer is incremented
by 1 to indicate the location where the next error record will
be recorded as an offset from the beginning of the Error Log
Area (A100).
A50014
Turn this bit ON to reset the Error Log Pointer (A300) to 00.
A400
When a non-fatal error (user-defined FALS(006) or system
error) or a fatal error (user-defined FALS(007) or system
error) occurs, the 4-digit hexadecimal error code is written to
this word.
