507 Stop or (1) When the AD57(S1) or AD58 was
Continue executing instructions in divided
(set by processing mode, other instructions
parameter) were executed to either of them.
(2) When an AD57(S1) or AD58 was
executing instructions in divided
processing mode, other instructions
were executed in divided mode to
another AD57(S1) or AD58.
508 A CC-Link dedicated command was
issued to three or more CC-Link
modules.
509 (1) An instruction which cannot be
executed by remote terminal
modules connected to the MNET/
MINI-S3 was executed to the
modules.
(2) Though there are 32 entries of
FROM
with a
mailbox (memory area waiting for
execution), another
is executed to cause an overflow in
the mail box (memory area waiting
for execution).
(3) The

The

PIDINIT
The program presently executed
was specified by the
instruction.
(4) The number of CC-Link dedicated
command executed in one scan
exceeded 10.
— STOP (1) The CPU malfunctioned due to
noise.
(2) Hardware failure.
— (1) The power supply module detected
an incorrect power waveform.
(2) Failure in the power module, CPU
module, main base unit or
expansion cable is detected.
— Continue (1) The battery voltage for the CPU
module has dropped below the
specified value.
(2) The lead connector of the CPU
module battery is disconnected.
(M9006 is ON.)
(3) The battery voltage for the memory
card has dropped below the
specified value. (M9048 is ON.)

Corrective Action
AD57 (S1) and AD58 cannot be used
with QCPU-A.
Review the program.
The CC-Link dedicated command can be
issued only to two or less CC-Link
modules.
(1) Read the error step using a peripheral
device and correct the program,
meeting loaded conditions of remote
terminal modules.
(2) Use special register D9081 (number
of empty entries in mailbox) or
special relay M9081 (BUSY signal of
mail box) to suppress registration or
execution of the instruction.
PRC
(3) Correct the program specified by the
instruction to other.
ZCHG
(4) Set the number of CC-Link dedicated
commands executed in one scan to
10 or less.
(1) Take proper countermeasures for
noise.
(2) Hardware failure.
(1) Correct the power waveform applied
to the power supply module.
(2) Replace the power module, CPU
module, main base unit or expansion
cable.
(1) Replace the battery of the CPU
module.
(2) Connect the lead connector when
using the built-in RAM or the memory
retention function during power
failure.
(3) Replace the battery of the memory
card.
