Corrective Action
Any of the mounted modules is experiencing a
hardware fault. Therefore, check the mounted
modules and change the faulty module. (Please
consult your local Mitsubishi representative,

• Reset the CPU module and run it again. If the
same error code is displayed again, the cause is
a hardware failure of the CPU module, I/O
module, intelligent function module, END cover,
branch module, or extension module. (Please
consult your local Mitsubishi representative,
explaining a detailed description of the
problem.)
• Correct the interrupt pointer setting in the PLC
system setting of the PLC Parameter dialog box.
• Take measures not to issue an interruption from
the modules where the interrupt pointer setting
is not configured in the PLC system setting of
the PLC Parameter dialog box.
• Correct the interrupt setting of the network
parameter.
• Correct the interrupt setting of the intelligent
function module buffer memory.
• Correct the basic program of the QD51.
• Correct the interrupt pointer setting in the PLC
System tab of the PLC Parameter dialog box.
• Take measures not to issue an interruption from
the modules where the interrupt pointer setting
is not configured in the PLC System tab of the
PLC Parameter dialog box.
• Correct the Interrupt Setting of the network
parameter.
• Correct the interrupt setting of the intelligent
function module buffer memory.
• Reset the CPU module and run it again. If the
same error code is displayed again, the cause is
a hardware failure of the CPU module, I/O
module, intelligent function module, END cover,
branch module, or extension module. (Please
