Reservation setting of the CPU module
The reservation setting of the CPU modules excluding CPU No.1 is possible to reserve CPU numbers for the CPU modules to
be mounted in the future. ( Page 74 Module status setting)
However, if an actually mounted CPU module is set to the disabled status, the module is not to be regarded as an empty slot.

The CPU module can be mounted on the CPU slot and the slot number 0 to 6, where the opening slot between CPU modules
can be reserved as an empty slot. I/O modules and intelligent function modules, however, cannot be mounted on the opening
slot between CPU modules.
