(SD0)
The slot to which the QI60 is mounted
is set to other than Inteli (intelligent
function module) or Interrupt (interrupt
module) in the I/O assignment of PLC
parameter.
• In the I/O assignment setting of PLC
parameter, Inteli (intelligent function
module) was allocated to an I/O
module or vice versa.
• In the I/O assignment setting of PLC
parameter, a module other than
CPU (or nothing) was allocated to
the location of a CPU module or 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 parameter I/O allocation
2100 settings, an Inteli (intelligent function
module) was allocated to a location
reserved for an I/O module or vice
versa.
• In the parameter I/O allocation
settings, a module other than CPU
(or nothing) was allocated to a
location reserved for a CPU module
or vice versa.
• 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.
In PLC parameter I/O allocation
settings, a special function module
was allocated to a location reserved
for an I/O module. Or, the opposite has
happened.

Corrective Action
Make setting again to match the PLC
parameter I/O assignment with the
actual loading status.
• Make the PLC parameter's I/O
assignment setting again so it is
consistent with the actual status of
the intelligent function module and
the CPU module.
• Delete the switch setting in the I/O
assignment setting of the PLC
parameter.
Reset the parameter I/O allocation
setting to conform to the actual status
of the intelligent function module and
the CPU module.
Reset the PLC parameter I/O
allocation setting to conform with the
actual status of the special function
modules.
