22. TROUBLE SHOOTING
3003
[PARAMETER ERROR]
■Collateral informationmmon
• Common Information:File name/Drive name
• Individual Information:Parameter number
■Diagnostic Timing
• When an END instruction executed
• Read the individual information of the error using
the peripheral device, check the parameter item
corresponding to the numerical value (parameter
No.), and correct it.
• If the error is still generated following the
correction of the parameter settings, the possible
cause is the memory errorm of the CPU module's
built-in RAM or program memory or the memory
card. (Contact your local Mitsubishi
representative.)
RUN:

QnA
[PARAMETER ERROR]
The number of devices set at the PLC parameter
device settings exceeds the possible CPU module
range.
■Collateral informationmmon
• Common Information:File name/Drive name
• Individual Information:Parameter number
■Diagnostic Timing
• At power-On/At reset/STOP RUN/
At writing to progurammable controller
3004
[PARAMETER ERROR]
The parameter file is incorrect.
Alternatively, the contents of the file are not
parameters.
■Collateral informationmmon
• Common Information:File name/Drive name
• Individual Information:Parameter number
■Diagnostic Timing
• At power-On/At reset/STOP RUN/
At writing to progurammable controller
Check whether the parameter file version
is .QPA, and check the file contents to be
sure they are parameters.
3100
[LINK PARA. ERROR]
Although the QnACPU is a control station or master
station, the network parameters have not been
written.
■Collateral informationmmon
• Common Information:File name/Drive name
• Individual Information:Parameter number
■Diagnostic Timing
• At power ON/At reset/STOP RUN
• Correct and write the network parameters.
• If the error occurs after correction, it suggests a
hardware fault. (Contact your local Mitsubishi
representative.)
3101
[LINK PARA. ERROR]
• 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.
• The network class specified by a network
parameter is different from that of the actually
mounted network.
• The network refresh parameter of the
MELSECNET/H, MELSECNET/10 is out of the
specified area.
■Collateral informationmmon
• Common Information:File name/Drive name
• Individual Information:Parameter number
■Diagnostic Timing
• At power ON/At reset/STOP RUN
• 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.)
3102
[LINK PARA. ERROR]
• The network module detected a network
parameter error.
■Collateral informationmmon
• Common Information:File name/Drive name
• Individual Information:Parameter number
■Diagnostic Timing
• At power ON/At reset/STOP RUN
*3
• Correct and write the network parameters.
• If the error occurs after correction, it suggests a
hardware fault. (Contact your local Mitsubishi
representative.)
