error code Error description and cause Corrective action
3000
In a multiple CPU system, the intelligent function module controlled by
another CPU has been specified in the interrupt event setting of the
Parameter.
• In the interrupt event setting of the Parameter, specify the start I/O
No. of the intelligent function module controlled by the host CPU.
• Delete the interrupt event setting of the Parameter.
The empty slot points on the Parameter is not set within the applicable
range of the C Controller module setting.
• Read the error information from the C Controller setting utility, check
the parameter item corresponding to the numerical value
(parameter No.), and correct it if necessary.
• Rewrite the corrected parameters to the C Controller module and
reload the power supply of the C Controller system or reset the
module.
• If the same error occurs again, it is thought to be a hardware failure.
Please consult your local Mitsubishi service center or
representative, explaining the details of the problem.
3001 The parameter settings are corrupted.
• Read the error information from the C Controller setting utility, check
the parameter item corresponding to the numerical value
(parameter No.), and correct it if necessary.
• Rewrite the corrected parameters to the C Controller module and
reload the power supply of the C Controller system or reset the
module.
• If the same error occurs again, it is thought to be a hardware failure.
Please consult your local Mitsubishi service center or
representative, explaining the details of the problem.
3010
In a multiple CPU system, the number of CPU modules set in the
Parameter differs from that of actually mounted modules.
Match the number of CPUs in the multiple CPU setting parameter (No.
of CPUs in multiple CPU settings - CPU (Empty) setting of I/O
assignment) with that of actually mounted CPUs.
3012
Multiple CPU setting or control CPU setting differs from the reference
CPU settings in a multiple CPU system.
Match the multiple CPU setting or control CPU setting in the
programmable controller parameter with the reference CPU (CPU
No.1) settings.
3014
In a multiple CPU configuration, the online module change parameter
setting (multiple CPU system parameter) is different from that of the
reference CPU.
Match the online module replacement parameter with that of the
reference CPU (CPU No.1).
In a multiple CPU configuration, the online module change setting is
enabled though the mounted CPU module does not support the online
module change parameter.
Disable the online module change setting when the mounted CPU
module does not support the online module change parameter.
3100
In a multiple CPU system, a MELSECNET/H module controlled by
another CPU is specified for the start I/O No. of the MELSECNET/H
network parameter.
• Delete the MELSECNET/H network parameter of the MELSECNET/
H module controlled by another CPU.
• Change the start I/O No. of the MELSECNET/H module controlled
by the host CPU.
The link parameter of the MELSECNET/H operating as a normal
station was changed to the control station, or the link parameter of the
MELSECNET/H operating as a control station was changed to a
normal station.(The link parameter is updated on the module side by
reseting.)
Reset the CPU module.
• The number of actually installed modules is different from that
designated in the number of modules setting parameter of
MELSECNET/H.
• The start I/O No. of the MELSECNET/H network parameter differs
from the actual I/O No.
• Some data in the parameters cannot be handled.
• The station type of MELSECNET/H has been changed while the
power is on. (RESET RUN is required to change the station type.)
• 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 even after performing the above checks, it
indicates a hardware fault. Please replace the faulty module, or
consult your local Mitsubishi service center or representative,
explaining the details of the problem.
