• The buffer memory size of an intelligent
function module is incorrect.
• An unsupported module is mounted.
• An unsupported module is mounted.
• An intelligent function module error was
detected. (Handshake error)
Stop/
• An I/O module (including intelligent
*3
function modules and special function
modules) is being removed, was
removed. or mounted during operation.
The FROM/TO instruction cannot be
Stop executed due to a control bus error with an
intelligent function module.
In the multiple CPU system, a CPU module
Stop incompatible with the multiple CPU system
is mounted.
An error was detected on the system bus.
Stop • Self-diagnostic error of the system bus
• Self-diagnostic error of the CPU module
• Failure of a mounted module was
detected.
Stop • In the multiple CPU system, a CPU
module incompatible with the multiple
CPU system is mounted.
Corrective action
• In the hardware diagnostic test, execute
the battery backup RAM diagnostic test
(mode 1).
<When completed normally>
For Q24DHCCPU-VG, clear the Battery
backup RAM monitor screen with
Setting/monitoring tools for the C
Controller module, and then restart the C
Controller module.
For Q24DHCCPU-V/Q24DHCCPU-LS/
Q26DHCCPU-LS/Q12DCCPU-V,
perform the module initialization setting
procedure, and restart the C Controller
module.
<When failed>
Replace the C Controller module.
• Check for any battery error, and replace
the battery, if any.
• Take a preventive measure against noise
• Initialize the module to restore the
default status of the module.
Check the ERR. LED of each output
module, and replace the module whose
ERR. LED is on.
• Read the error information in Setting/
monitoring tools for the C Controller
module, and replace the fuse of the
output module that corresponds to the
value (module No.)
• If a GOT is connected to the main or
extension base unit in a bus topology,
check the extension cable connection
and the GOT grounding status.
Check the I/O assignment and the actually
mounted module.
Check the modules and replace a faulty
module.
• When unsupported module is mounted,
remove the module.
• If the module is supported, check the
modules and replace a faulty module.
• When unsupported module is mounted,
remove the module.
• If the module is supported, check the
modules and replace a faulty module.
• Reset the C Controller module and set it
to RUN again.
• If the same error is displayed again,
check the modules and replace a faulty
module.
• Remove the incompatible CPU module
from the main base unit.
• Replace the incompatible CPU module
with a compatible one.
• Mount the CPU modules in the CPU slot
and slot 0 to 2.
• Check the modules and replace a faulty
module.
• Reset the C Controller module and set it
to RUN again.
• If the same error is displayed again,
check the modules and replace a faulty
module.
• Remove the incompatible CPU module
from the main base unit.
• Replace the incompatible CPU module
with a compatible one.
• Reset the C Controller module and set it
to RUN again.
• If the same error is displayed again,
check the modules and replace a faulty
module.
