A394 A394.08
to
A394.15 Serial Port 1
PT Priority
Registered
Flags The corresponding bit will be ON for
the PT that has priority when the
serial port 1 is communicating in NT
link mode.
Bits 0 to 7 correspond to units 0 to 7.
These flags are written when the pri-
ority registration command is
received.
ON: Priority

Counter
(No-protocol
Mode)
Indicates (in binary) the number of
bytes of data received when serial
port 1 is in no-protocol mode. --- Retained Cleared Refreshed

is received. ---
A395 A395.10 ER/AER Flag
for Back-
ground Execu-
tion
ON when an instruction processing
error or an illegal area access error
occurs during background process-
ing. ON: Error.
OFF (0) when
power is
turned ON.
OFF (0) when
operation
starts.
OFF: No
errors. OFF

background
processing
starts.

A395.11 Memory Cor-
ruption
Detected Flag
ON when memory corruption is
detected when the power supply is
turned ON. ON: Memory
corruption
OFF: Normal

A395.12 DIP Switch
Pin 6 Status
Flag
The status of pin 6 on the DIP switch
on the front of the CPU Unit is written
to this flag every cycle. ON: Pin 6 ON
OFF: Pin 6

A400 All Error code When a non-fatal error (user-defined
FALS(006) or system error) or a fatal
error (user-defined FALS(007) or
system error) occurs, the 4-digit
hexadecimal error code is written to
this word. When two or more errors
occur simultaneously, the highest
error code will be recorded. --- Cleared Cleared Refreshed
when error
occurs. ---
A401 A401.00 Other Fatal
Error Flag
ON when a fatal error that is not
defined for A401.01 to A401.15
occurs. Detailed information is output
to the bits of A314.
There are no errors that affect this
flag at this time. This flag is reserved
by the system.
OFF: No
other fatal
error
ON: Other

occurs. A314
A401.06 FALS Error
Flag
(fatal error)
ON when a fatal error is generated
by the FALS(006) instruction. The
CPU Unit will stop operating and the
ERR/ALM indicator will light.
The corresponding error code will be
written to A400. Error codes C101 to
C2FF correspond to FALS numbers
001 to 511.
This flag will be turned OFF when
the FALS errors are cleared.

A401.08 Cycle Time
Too Long Flag
(fatal error)
ON if the cycle time exceeds the
maximum cycle time set in the PLC
Setup (the cycle time monitoring
time). CPU Unit operation will stop
and the ERR/ALM indicator on the
front of the CPU Unit will light.
This flag will be turned OFF when
the error is cleared.
OFF: Cycle
time under
max.
ON: Cycle
time over
