Corrective action
• Reduce the number of connectable
modules to 10 or less.
• Remove the module whose number of
points exceeds 4096 points.
• Replace the last module with the one
whose number of occupied points is within
4096.
• 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.
