(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 in PLC parameter ("I/O Assignment").
Ex.
Setting "PLC (Empty)" between CPU modules
When a Universal model QCPU is used, "PLC (Empty)" can be set between CPU modules.
This is useful when adding a CPU module to the system in the future. No program modification is required because the CPU
number set as an empty slot can be assigned to the added CPU module.
Note, however, that when the following CPU module is used, "PLC (Empty)" cannot be set to the left of the CPU module.
• High Performance model QCPU
• Process CPU
To add a High Performance mode QCPU 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.
3.3.3 Available I/O modules and intelligent function modules
Refer to the system configuration using a a High Performance model QCPU or Process CPU as CPU No.1.
