MODULE
(c) "CPU (Empty)" setting
An empty slot can be reserved for future addition of a CPU module.
Set the number of CPU modules, including the one on the empty slot, in "No. of
CPU" on the <<Multiple CPU setting>> tab of the C Controller Setting Utility.
After that, set the type "CPU (Empty)" to the slot on the right side of the mounted
CPU module (s) on the <<I/O assignment setting>> tab of the C Controller setting
utility.
(Example) When the No. of CPUs is set to 4 in the Multiple CPU setting and two
C Controller modules and one Motion CPU are mounted
Mount the C Controller modules to the CPU slot and Slot 0 and the
Motion CPU to Slot 1, and set Slot 2 to "CPU (Empty)".
POINT
When the C Controller module is used, "CPU (Empty)" cannot be set between
CPU modules.
However, since no mounting position priorities are given between the C Controller
module and Motion CPU, either of them can be added without shifting the CPU
module at the right end.
