Corrective action
• Reduce the number of MELSECNET/H
modules to four or less.
• Reduce the number of Ethernet modules to
four or less.
• Mount only one MELSECNET/H module.
• Mount only one Ethernet module.
• Reduce the number of CC-Link modules to
two or less.
Check the network number and station
number.
Mount only one Ethernet module.
Reduce the number of Ethernet modules to
two or less.
Configure the I/O assignment setting of the
PLC parameter again so that it is consistent
with the actual status of the intelligent
function modules, special function modules,
and I/O modules.
• Configure the start X/Y again in the I/O
Assignment tab of "PLC Parameter"
according to the intelligent function module
and I/O modules connected.
• 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.
