module) is set for the slot where an I/O module
is mounted, and vice versa.
• In the I/O Assignment tab of the PLC parameter
dialog box, a module other than a CPU module
or empty is set for the slot where a CPU module
is mounted, and vice versa.
• In the I/O assignment setting of the PLC
parameter, switch setting was made to the
module that has no switch setting.
• In the I/O assignment setting of the PLC
parameter dialog box, the number of points
assigned to the intelligent function module is
less than the number of points of the mounted
module.

less than the number of points of the mounted
module.
■Collateral information

■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
• In the I/O Assignment tab of the PLC parameter
dialog box, "Intelligent" (intelligent function
module) or a branch module is set for the
position where an I/O module is connected.
• In the I/O Assignment tab of the PLC parameter
dialog box, "Input" (input module), "Output"
(output module), or a branch module is set for
the position where an intelligent function module
is connected.
• In the I/O Assignment tab of the PLC parameter
dialog box, "Input" (input module), "Output"
(output module), or "Intelligent" (intelligent
function module) is set for the position where a
branch module is connected.
• In the I/O Assignment tab of the PLC parameter
dialog box, switch settings are configured for the
module that does not support the setting.
• 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

Corrective Action
• Set the I/O assignment again so that the setting
matches with the mounting status of the
intelligent function module or the CPU module.
• Delete the switch setting in the I/O assignment
setting of the PLC parameter.
Set the I/O assignment again so that the setting
matches with the mounting status of the intelligent
function module or the CPU module.
• Set the I/O assignment again so that the setting
matches with the mounting status of the
intelligent function module, CPU module, or
branch module.
• 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, END cover,
branch module, or extension module. (Please
consult your local Mitsubishi representative,
explaining a detailed description of the
problem.)
