Corrective Action
• Remove the module mounted on the 25th slot
or later slot. (The 17th slot or later slot for the
Q00J.)
• Remove the module mounted on the slot
whose number is greater than the number of
slots specified at [Slots] in [Standard setting] of
the base setting.
• Remove the module mounted on the slot
whose number of I/O points exceeds 1024
points (greater than or equal to 256 points for
the Q00J).
• Replace the module with the one whose
number of occupied points does not exceed
1024 points (within 256 points for the Q00J).
• Reduce the number of connectable modules to
10.
• Remove the module whose number of points
exceeds 4096 points.
• Replace the module to installed at end with the
one whose number of occupied points does not
exceed 4096 points.
• 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, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
• Reduce the number of connectable modules to
10.
• Remove the module whose number of points
exceeds 1024 points.
• Replace the module with the one whose
number of occupied points does not exceed
1024 points.
• 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, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
• Install a usable module.
• The intelligent function module/special function
module is experiencing a hardware fault.
(Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
• Connect an applicable module.
• 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, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
