Error Contents and Cause
Code
[SP. UNIT LAY ERR.]
• In the I/O Assignment tab of the PLC Parameter
dialog box, an intelligent function module was
assigned to the slot for an I/O module. Or vice
versa.
• In the I/O Assignment tab of the PLC Parameter
dialog box, an intelligent function module was
assigned to the slot for an I/O module.
2100
• In the I/O Assignment tab of the PLC Parameter
dialog box, the number of points assigned to the
intelligent function module is less than that of the
mounted module.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
13 or more A-series special function modules
(except for the A1SI61) that can initiate an
interrupt to the CPU module have been installed.
2101 ■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
Seven or more A1SD51S have been installed.
■Collateral information
• Common information: Module No. (Slot No.)
2102
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
• Two or more QI60/A1SI61 modules are mounted
in a single CPU system.
• Two or more QI60/A1SI61 modules are set to
the same control CPU in a multiple CPU system.
• Two or more A1SI61 modules are loaded in a
multiple CPU system.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
2103
Two or more QI60, A1SI61 interrupt modules have
been mounted.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
Two or more QI60 modules are mounted.

Corrective Action
• Set the parameter again in the I/O Assignment
tab of the PLC Parameter dialog box according
to the CPU module mounted.
• Delete the switch setting.
• 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.)
Reduce the A series special function modules
(except the A1SI61) that can make an interrupt
start to the CPU module to 12 or less.
Keep the number of A1SD51S to six or fewer.
• Reduce the number of QI60/A1SI61 modules
mounted in the single CPU system to one.
• Change the number of QI60/A1SI61 modules
set to the same control CPU to only one in the
multiple CPU system.
• Reduce the number of A1SI61 modules to only
one in the multiple CPU system. When using
an interrupt module with each QCPU in a
multiple CPU system, replace it with the QI60.
(Use one A1SI61 module + max. three QI60
modules or only the QI60 modules.)
Install only 1 QI60, A1SI61 module.
Reduce the QI60 modules to one.
