MODULE
(2) When CPU No. 1 is Basic model QCPU
The mounting position of each CPU module is shown in Table13.3.
(a) Mounting position of Basic model QCPU
Only one Basic model QCPU can be mounted on the CPU slot (slot on the right-
hand side of the power supply module) of the main base unit.
(b) Mounting position of Motion CPU
Only one Motion CPU can be mounted to slot 0 on the right of the Basic model
QCPU.
It cannot be mounted to other than slot 0.
(c) Mounting position of C Controller module
Only one C Controller module can be mounted at the right end of CPU modules.
No CPU can be mounted on the right side of the C Controller module.
(d) "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 "CPU (Empty)" for the empty slot type in on the <<I/O assignment
setting>> tab of the C Controller setting utility.
1) When adding the Motion CPU in the future.
Set slot 0 as "CPU (Empty)."
