In a multiple CPU system, the
MELSECNET/H under control of
another CPU is specified as the head I/
O number in the network setting
parameter of the MELSECNET/H.
• Delete the MELSECNET/H network
parameter of the MELSECNET/H
under control of another CPU.
• Change the setting to the head I/O
number of the MELSECNET/H under
control of the host CPU.

The network parameter of the
MELSECNET/H operating as the
normal station is overwritten to the
control station.
Or, the network parameter of the
MELSECNET/H operating as the
control station is overwritten to the
normal station. (The network parameter
is updated on the module by resetting.)
Reset the CPU module.

QnU
• The number of actually installed
modules is different from that
designated in the number of modules
setting parameter of MELSECNET/H.
• The head I/O number of actually
installed modules is different from
that designated in the network
parameter of MELSECNET/H.
• Some data in the parameters cannot
be handled.
• The network type of MELSECNET/H
is overwritten during power-on.
(When changing the network type,
switch RESET to RUN.)
• The mode switch of MELSECNET/H
module
*5
is outside the range.
• Check the network parameters and
actual mounting status, and if they
differ, make them matched.
If any network parameter has been
corrected, write it to the CPU module.
• Check the extension base unit stage
No. setting.
• Check the connection status of the
extension base units and extension
cables.
When the GOT is bus-connected to
the main base unit and extension
base units, also check the connection
status.
If the error occurs after the above
checks, the possible cause is a
hardware fault. (Contact your local
Mitsubishi representative, explaining a
detailed description of the problem.)
• Set the mode switch of MELSECNET/
H module
*5
within the range.
QCPU
Although the QnACPU is a control
station or master station, the network
parameters have not been written.
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)
