MULTIPLE CPU SYSTEM CONCEPT
(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 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 and two High Performance model
QCPUs and one C Controller module are mounted
Mount the High Performance model QCPUs on the CPU slot and Slot
0 and the C Controller module on Slot 1, and set Slot 2 to "CPU
(Empty)".
Mounting allowed
CPU 0 1 2
POINT
When using the High Performance model QCPU, "CPU (Empty)" cannot be set
between CPU modules.
To add a High Performance model QCPU or Motion CPU to a system where the C
Controller module is used, shift the C Controller module to the right because no
CPU module is allowed on the right side of the C Controller module.
CPU 0 1 2
Addition
Move to the right.
