• At power-on/At reset
[SP. UNIT LAY ERR.]
• Two or more MELSECNET/H modules were
installed.
• Two or more Ethernet modules were installed.
• Three or more CC-Link modules were installed.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
• The same network number or same station
number is duplicated in the MELSECNET/H
network system.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
The start X/Y set in the PLC parameter's I/O
assignment settings is overlapped with the one for
another module.
■Collateral information

Corrective Action
• Reduce the CC-Link IE controller network
modules up to two or less in the entire system.
• Reduce the total number of the MELSECNET/
H and CC-Link IE controller network modules
up to four or less in the entire system.
• Reduce the number of MELSECNET/H
modules to four or less.
• Reduce the number of Ethernet modules to four
or less.
• 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, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
