Function
ON when there is a setting error in the
PLC Setup. The CPU Unit will continue
operating and the ERR/ALM indicator
on the front of the CPU Unit will flash.
Note This flag will be turned OFF when
the error is cleared.
ON when a non-fatal error is generated
by executing FAL. The CPU Unit will
continue operating and the ERR/ALM
indicator on the front of the CPU Unit
will flash.
The bit in A360 to A391 that corre-
sponds to the FAL number specified in
FALS will be turned ON and the corre-
sponding error code will be written to
A400. Error codes 4101 to 42FF corre-
spond to FAL numbers 001 to 2FF (0 to
511).
Note This flag will be turned OFF when
the error is cleared.
Memory Error Flag (A401.15) is turned
ON and one of the following flags is
turned ON to indicate the memory area
where the error occurred
A403.00: Ladder program
A403.04: PLC Setup
When a memory error occurs, the CPU
Unit will continue operating and the
ERR/ALM indicator on the front of the
CPU Unit will flash.
Note The corresponding flag will be
turned OFF when the error is
cleared.
ON when the built-in EEPROM backup
memory is physically destroyed.
Contains information on I/O bus errors.
The CPU Unit will stop operating and
the ERR/ALM indicator on the front of
the CPU Unit will light.
Note A401.14 (I/O Bus Error Flag) will
turn ON.
The 3-digit binary value of these bits
indicates the cause of the Too Many
I/O Points Error.
The bit corresponding to the option slot
turns ON when an error occurs in an
Option Board (A315.13 will be ON).
Bit 01: Option slot 2
On when AD0 open-circuit is detected
On when AD1 open-circuit is detected
ON when the built-in analog initializa-
tion is normally finished.
