Error
Code Error Contents and Cause
(SD0)
Although the QnACPU is a control
3100 station or master station, the network
parameters have not been written.
• The network No. specified by a
network parameter is different from
that of the actually mounted network.
• The head I/O No. specified by a
network parameter is different from
that of the actually mounted I/O unit.
3101
• The network class specified by a
network parameter is different from
that of the actually mounted network.
• The network refresh parameter of the
MELSECNET/10 is out of the
specified area.
• The network module detected a
3102
network parameter error.
Corrective Action
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)
• Check the network parameters and
mounting status, and if they differ,
match the network parameters and
mounting status.
If any network parameter has been
corrected, write it to the CPU module.
• Confirm the setting of the number of
extension stages of the extension
base units.
• 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 their
connection status.
• If the error occurs after the above
checks, the cause is a hardware fault.
(Contact your local Mitsubishi
representative, explaining a detailed
description of the problem.)
• Correct and write the network
parameters.
• If the error occurs after correction, it
suggests a hardware fault. (Contact
your local Mitsubishi representative.)
