ON when program contents are incorrect.
CPU Unit operation will stop and the ERR/ALM indica-
tor on the front of the CPU Unit will light. The task
number where the error occurred will be stored in
A294 and the program address will be stored in A298
and A299.
The type of program error that occurred will be stored
in bits 8 to 15 of A295. Refer to the description of A295
or to 2-3 Checking Programs of CS/CJ Series Pro-
grammable Controllers (W394) for more details on
program errors.

0: No error
This flag will be turned OFF when the error is cleared.
ON when a Unit in the registered I/O tables does not
agree with the Unit in the real I/O tables (i.e., the Unit
actually connected).
CPU Unit operation will stop and the ERR/ALM indica-
tor on the front of the CPU Unit will light.

• Two Special I/O Units have been assigned the same
unit number.
• Two Basic I/O Units have been allocated the same
data area words.
CPU Unit operation will stop and the ERR/ALM indica-
tor on the front of the CPU Unit will light.
The duplicated unit number is indicated in A409 to
A416.
