(f) Empty slot setting
Empty slots can be reserved for future addition of CPU modules. Set the number of CPU modules including 
empty slots in "No. of PLC" of PLC parameter ("Multiple CPU Setting"). Then, set "PLC (Empty)" to the type of 
a target slot from the right in PLC parameter ("I/O Assignment").
Ex.
Setting the number of CPU modules to "4" in PLC parameter and mounting two High Performance model 
QCPUs and one Motion CPU
Mount the High Performance model QCPUs in the CPU slot and slot 0, and the Motion CPU in slot 1, and 
set "PLC (Empty)" to slot 2.
When a High Performance model QCPU or Process CPU is used, "PLC (Empty)" cannot be set between CPU modules. To 
add a CPU module to the system where a C Controller module or PC CPU module is used, move the C Controller module or 
PC CPU module to the right to allow addition of a CPU module.
