• The Ethernet, MELSECNET/H and
MELSECNET/10 use the same
network number.
• The network number, station
number or group number set in the
network parameter is out of range.
• The specified I/O No. is outside the
range of the used CPU module.
• The Ethernet-specific parameter
setting is not normal.
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)

In a multiple CPU system, the Q series
CC-Link module under control of
another station is specified as the
head I/O number of the CC-Link
network parameter.
• Delete the CC-Link network
parameter of the Q series CC-Link
module under control of another
station.
• Change the setting to the start I/O
number of the Q series CC-Link
module under control of the host
station.

• Though the number of CC-Link
modules set in the network
parameters is one or more, the
number of actually mounted
modules is zero.
• The start I/O number in the common
parameters is different from that of
the actually mounted module.
• The station type of the CC-Link
module count setting parameters is
different from that of the actually
mounted station.
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)

• The CC-Link parameter setting is
incorrect.
• The set mode is not allowed for the
version of the mounted CC-Link
module.
Check the parameter setting.
