• The network module detected a
network parameter error.
• A MELSECNET/H network
parameter error was detected.
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)
The station No. specified in pairing
setting are not correct.
• The stations are not numbered
consecutively.
• Pairing setting has not been made
for the CPU module at the normal
station.
Refer to the troubleshooting of the
network module, and if the error is due
to incorrect pairing setting, reexamine
the pairing setting of the network
parameter.
QnPRH
3103
In a multiple CPU system, the Q series
Ethernet interface module under
control of another station is specified
to the start I/O number of the Ethernet
network parameter.
• Delete the Ethernet network
parameter of the Q series Ethernet
interface module under control of
another station.
• Change the setting to the start I/O
number of the Q series Ethernet
interface module under control of
the host station.

• Although the number of modules
has been set to 1 or greater number
in the Ethernet module count
parameter setting, the number of
actually mounted module is 0.
• The start I/O No. of the Ethernet
network parameter differs from the I/
O No. of the actually mounted
module.
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)
Rem
• AJ71QE71 does not exist in the
position of I/O number set by the
parameter.
• I/O number designation is
overlapping.
• Numbers of the network parameter
and loaded AJ71QE71 are different.
• Ethernet (parameter + dedicated
instruction) is set to more than 5.
