Flag (Single

ON when a non-fatal error is generated
by executing FAL(006). 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 corresponds
to the FAL number specified
in FALS(006) will be turned ON and
the corresponding error code will be
written to A400. Error codes 4101 to
42FF correspond to FAL numbers
001 to 2FF (0 to 511).
(This flag will be turned OFF when
the error is cleared.)
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.
A40300: User program
A40304: PLC Setup
A40305: Registered I/O Table
A40307: Routing Table
A40308: 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 startup
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 Card 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.)
Turns ON when the flash memory
fails.
Contains the 8-bit binary slot number
(00 to 09) where an I/O Bus
Error occurred.
CPU Unit operation will stop and the
ERR/ALM indicator on the front of
the CPU Unit will light. The I/O Bus
Error Flag (A40114) will be ON.
(This flag will be turned OFF when
the error is cleared.)
Contains the 8-bit binary rack number
(00 to 07) where an I/O Bus
Error occurred.
CPU Unit operation will stop and the
ERR/ALM indicator on the front of
the CPU Unit will light. The I/O Bus
Error Flag (A40114) will be ON.
(This flag will be turned OFF when
the error is cleared.)
Turns ON when the peripheral servicing
time in a Parallel Processing
Mode exceeds 2 s. This will also
cause a cycle time error and operation
will stop.
