Error details and cause
The following problem exist in a module
specified in Data refresh settings:
• The module other than intelligent function
module/special function module
• The module that does not include buffer
memory
• The module being accessed is faulty.
• No module is installed.
• Writing into a CPU shared memory of
other than the host station is set.
• Any module controlled by another
module is specified in Data refresh
settings.
• Any module for A and QnA series
controlled by another module is specified
in Data refresh settings.
When the online module change setting is
set to be "enabled" in the PLC parameter in
a multiple CPU system, an intelligent
function module controlled by another
module is specified in Data refresh settings.
• In the single CPU system, the QAB or
QA1SB base unit is used.
• In a multiple CPU system configuration, a
C Controller module is set as a CPU that
controls modules on the QAB or
QA1SB.
A CPU module is installed to other than the
CPU slot and slot 0 to 2.
The QA1SB is used as the main base
unit.
• A module is installed in the position of
slot 65 or higher.
• A module is installed in the position of the
slot number that exceeds the number of
slots set for the base unit.
• A module is installed in the slot where I/O
points of 4096 or higher are assigned.
• A module is installed in the slot whose
assigned I/O points cross over the
boundary of 4096.
• A module that cannot be recognized is
mounted.
• No response returns from an intelligent
function module.
In the multiple CPU system, CPU modules
are configured as follows:
• The slot on the left of a CPU module is
empty.
• A CPU module other than High
Performance model QCPUs is mounted
on the left of a High Performance model
QCPU.
• When CPU No.1 is a High Performance
model QCPU, a CPU module other than
C Controller modules is mounted on the
right of a C Controller module.
• When CPU No.1 is a C Controller
module, a programmable controller CPU
is mounted on the right of the C
Controller module.
• When CPU No.1 is a Basic model QCPU,
a CPU module is mounted on the right of
the C Controller module.
In the multiple CPU system, an intelligent
function module incompatible with the
multiple CPU system is set to be controlled
by a CPU other than CPU No.1.
APPENDICES
Corrective action
• Read the error information in Setting/
monitoring tools for the C Controller
module to identify the numeric value
(module No.). Correct the data refresh
setting corresponding to the value as
necessary.
• Check the destination intelligent function
module/special function module and
replace a faulty module.
Read the error information in Setting/
monitoring tools for the C Controller module
to identify the numeric value (module No.).
Correct the data refresh setting
corresponding to the value as necessary.
• When performing the online module
change in a multiple CPU system,
correct the data refresh setting so that
access will not be made to the intelligent
function module controlled by the other
CPU.
• When accessing the intelligent function
module controlled by the other CPU in a
multiple CPU system, set the online
module change setting to be "disabled"
by parameter.
• Replace the base unit with the QB.
• Set a High Performance model QCPU as
a CPU that controls the modules on the
QAB or QA1SB.
Check the slot position of the C Controller
module and install the CPU module in the
correct slot.
Change the main base unit to the QB.
• Remove the module in slot 65 or higher.
• Remove the module installed in the
position of the slot number that exceeds
the number of slots set for the base unit.
• Remove the module installed in the slot
where 4096 points or higher are
assigned.
• Replace the last module with a module
whose I/O points do not exceed 4096.
• Mount applicable modules.
• Check the modules and replace a faulty
module.
• Eliminate any empty slot space between
CPU modules. (An empty slot must be
set on the right side of CPU modules.)
• Replace the module other than High
Performance model QCPUs on the left of
the High Performance model QCPU with
a High Performance model QCPU.
• Remove the CPU module other than C
Controller modules on the right of the C
Controller module.
• Remove the programmable controller
CPU mounted on the right of the C
Controller module.
• Remove the CPU module mounted on
the right of the C Controller module.
• Change the module to an intelligent
function module that supports the
multiple CPU system (function version B
or later).
• Change the control CPU setting for the
intelligent function module to CPU No.1.
