Stopped
This word contains the task number
of the task that was being executed
when program execution was
stopped because of a program error.
(A298 and A299 contain the program
address where program execution
was stopped.)
Normal tasks:
0000 to 001F
(task 0 to 31)
Interrupt
tasks: 8000 to
80FF (task 0
to 255)

Error Flag
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.
CPU Unit operation will stop and the
ERR/ALM indicator will light when
this flag goes ON.
(The task number where the error
occurred will be stored in A294 and
the program address will be stored in
A298 and A299.)

Flag
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.) CPU Unit
operation will stop and the ERR/ALM
indicator will light when this flag goes
ON.
(The task number where the error
occurred will be stored in A294 and
the program address will be stored in

Illegal Access
Error Flag
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
memory is accessed illegally.) CPU
Unit operation will stop and the ERR/
ALM indicator will light when this flag
goes ON.
The following operations are consid-
ered illegal access:
1) Reading/writing the system area
2) Indirect DM BCD error (in BCD
mode)
(The task number where the error
occurred will be stored in A294 and
the program address will be stored in
