Error and cause
• Reduce the number of connected modules to 10 or less.
• Remove the module installed in the position corresponding to the I/O points of
4096 or greater.
• Replace the end module with a module so that the number of occupied points
does not exceed 4096.
• Reset the head module.
If this error occurs again, the hardware of the head module, I/O module,
intelligent function module, or END cover may be faulty. (Please consult your
local Mitsubishi representative.)
• Install an appropriate module.
