CHAPTER 1 OVERVIEW
In a multiple CPU system, more than one CPU module is mounted on the main base unit and each CPU module
controls I/O modules and intelligent function modules separately.
QCPUs, Motion CPUs, C Controller modules, and PC CPU modules can be used in multiple CPU systems.
( Page 31, CHAPTER 3)
Remark
This manual describes the combinations of CPU modules and communications among CPU modules in a multiple CPU
system. For the uses, functions, and instruction availabilities of each CPU module, refer to the following.
