A294 Task Number when
Program Stopped This word contains the task number of
the task that was being executed when
program execution was stopped
because of a program error.
Note A29 8 and A299 contain the pro-
gram address where program
execution was stopped.
Cyclic tasks: 0000
Interrupt tasks: 8 000
to 8 00F (task 0 to 15)

A295 0 8 Instruction Processing
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.
Note The task number where the error
occurred will be stored in A294
and the program address will be
stored in A29
8 and A299.

09 Indirect DM BCD Error
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.
Note The task number where the error
occurred will be stored in A294
and the program address will be
stored in A29

10 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
considered illegal access:
• Reading/writing the system area
• Indirect DM BCD error (in BCD
mode)
Note The task number where the error
occurred will be stored in A294
and the program address will be
stored in A29
8 and A299.
