CPU
operation Error details and cause
status
In the multiple CPU system, a CPU module
incompatible with the multiple CPU system
is mounted.

information input at power on.
(The I/O module mounting status was
changed during operation. Or, the module is
almost disconnected.)
In the I/O assignment parameter setting, the
slot of the QI60 is set to other than Intelli.
(intelligent function module) and Interrupt
(interrupt module).
• In the I/O assignment parameter setting,
an I/O module is set as an intelligent
function module, or vice versa.
• In the I/O assignment parameter setting,
Stop
a CPU module is set as another module
type or empty, or vice versa.
• In the I/O assignment parameter setting,
the number of points set for an intelligent
function module is less than the actual
number of points.
• In the I/O assignment parameter setting,
the switches were set for the module than
has no switch setting.
• Two or more QI60 modules are mounted
in the single CPU system.
• Two or more QI60/A1SI61 modules are
mounted for the same control CPU
(programmable controller CPU only) in
the multiple CPU system.
Stop
• Two or more A1SI61 modules are
mounted in the multiple CPU system.
Two or more QI60 modules with no interrupt
pointer setting are mounted.
A total of five or more MELSECNET/H
modules and/or CC-Link IE Controller
Network modules are mounted on the entire
system.
• Five or more MELSECNET/H modules
are mounted.
• Five or more CC-Link IE Controller
Stop
Network modules are mounted.
• Five or more Q series Ethernet modules
are mounted.
The same network No. or station No. is set
for different networks or stations on the
MELSECNET/H or CC-Link IE Controller
Network system.
The start X/Y set in the I/O assignment
Stop parameter setting is overlapped with the
one set for another module.
• A network module for the A2UCPU
(A1SJ71LP21, A1SJ71BR11,
A1SJ71LR21, A1SJ71AP21,
A1SJ71AR21, or A1SJ71AT21B) is
Stop
mounted.
• A network module for the Q2AS
(A1SJ71QLP21(S), A1SJ71QBR11, or
A1SJ71QLR21) is mounted.
Corrective action
Replace the incompatible CPU module with
a compatible one.
• Read the error information in Setting/
monitoring tools for the C Controller
module, check the module
corresponding to the value (module No.),
and replace the module.
• 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.
Correct the I/O assignment parameter
setting.
• Correct the I/O assignment parameters
to match them to the actual mounting
status of intelligent function modules and
CPU modules.
• In the I/O assignment parameter setting,
remove the switch settings.
• Use one QI60 in the single CPU system.
• Change the number of QI60 modules set
for the same control CPU to only one in
the multiple CPU system.
• Use only one A1SI61 in the multiple CPU
system.
• If an interrupt module is used for each
QCPU in the multiple CPU system,
replace it with the QI60. (Use one
A1SI61 and up to three QI60 modules, or
the QI60 modules only.)
• Use only one QI60.
• Configure the interrupt event settings for
the QI60 modules other than the first
one.
Reduce the total number of MELSECNET/
H modules and CC-Link IE Controller
Network modules on the entire system to
four or less.
• Reduce the number of MELSECNET/H
modules to four or less.
• Reduce the number of CC-Link IE
Controller Network modules to four or
less.
• Reduce the number of Q series Ethernet
modules to four or less.
Check the network numbers or station
numbers.
Correct the I/O assignment parameters to
match them to the actual mounting status of
intelligent function modules.
Replace the network module with a
MELSECNET/H module.
