2 MULTIPLE CPU SYSTEM
2.1.2 Installation position of CPU moduleUp to four PLC CPUs and Motion CPUs can be installed from the CPU slot (the right side slot of the power supply module) to slots 2 of the main base unit.
The Motion CPU module cannot be installed in the CPU slot.
The PLC CPU module must be installed in the CPU slot (CPU No.1) in the Multiple CPU system.
There is no restriction on the installation order for CPU modules (CPU No.2 to 4). (Note): Refer to the manual for each CPU module when the High performance PLC
CPU module, Process CPU module, PC CPU module and C controller module is mounted in the combination of Multiple CPU.
