Name
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 access ille-
gally.) 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:
Reading/writing the system area
Reading/writing EM File Memory
Writing to a write-protected area
Indirect DM/EM 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 A298 and A299.)
ON when there isn’t an END(001)
instruction in each program within a
task.
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.)
ON when a task error has occurred.
The following conditions generate a
task error.
•There isn’t even one regular task
that is executable (started).
•There isn’t a program allocated to
the task.
(The task number where the error
occurred will be stored in A294 and
the program address will be stored
in A298 and A299.)
The allowed value for Differentiation
Flags which correspond to differenti-
ation instructions has been
exceeded. 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.)
ON when a program that cannot be
executed has been stored. CPU Unit
operation will stop and the ERR/
ALM indicator will light when this flag
goes ON.
ON when the last address in UM
(User Memory) has been exceeded.
CPU Unit operation will stop and the
ERR/ALM indicator will light when
this flag goes ON.
