Function
When a memory error occurs, the
Memory Error Flag (A40115) is
turned ON and one of the following
flags is turned ON to indicate the
memory area where the error
occurred
A403.00: User program
A403.04: PLC Setup
A403.07: Routing Table
A403.08: CPU Bus Unit Settings
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.
(The corresponding flag will be
turned OFF when the error is
cleared.)
ON when automatic transfer at star-
tup has been selected and an error
occurs during automatic transfer. An
error will occur if there is a transfer
error, the specified file does not exist,
or the Memory Cassette is not
installed.
(This flag will be turned OFF when
the error is cleared by turning the
power OFF. The error cannot be
cleared without turning the power
OFF.)
ON when the flash memory is physi-
cally 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.
(A401.04 (I/O Bus Error Flag) will
turn ON.)
(This information will be cleared
when the error is cleared.)
When there is a setting error in the
PLC Setup, the location of that error
is written to A406 in 4-digit hexadeci-
mal.
The CPU Unit will continue operating
and the ERR/ALM indicator on the
front of the CPU Unit will flash.
(A406 will be cleared when the
cause of the error is eliminated.)
Always 0000 hex.
