Corrective Action
• Reduce the MELSECNET/H modules to one or
less.
• Reduce the Ethernet modules to one or less.
• Reduce the CC-Link modules to two or less.
• Check the network number and station number.
Make the PLC parameter's I/O assignment setting
again so it is consistent with the actual status of
the intelligent function module/special function
modules.
• Configure the start X/Y again in the I/O
Assignment tab of the PLC Parameter dialog
box 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,
explaining a detailed description of the
problem.)
Replace the network module for the A2USCPU,
Q2ASCPU, A2UCPU, or Q2ACPU with the
MELSECNET/H module.
