13.2 Outline of Multiple PLC Systems
(1) What is a multiple PLC system?
(a) A multiple PLC system is a system in which main base units are mounted
on several (maximum four) High Performance model QCPUs and motion
CPU in order to control the I/O modules and intelligent function modules.

The allowable CPU modules are shown in the table below.
PLC CPU Q02CPU, Q02HCPU, Q06HCPU, Q12HCPU, Q25HCPU,
Motion CPU Q172CPU, Q173CPU,Q172CPUN,Q173CPUN
PC CPU module PPC-CPU686(MS)-64, PPC-CPU686(MS)-128
Choose the CPU modules suitable to the system size and application to configure
the system.
It is necessary to set (control PLC setup) which High Performance model
QCPU and motion CPUs are to control which I/O modules and intelligent
function modules with a multiple PLC system.

(b) The CPU module that controls the I/O modules and intelligent function
modules is known as the "Control PLC".
The I/O modules and intelligent function modules controlled by the control
PLC are known "controled modules".
Other modules not controlled by the control PLC are known as "non-
controlled modules".

1: Indicates the grouping configuration on the GX Developer.
QCPU1 indicates the "PLC No.," and "1" on the I/O module and intelligent
function module indicates that their control PLC is the PLC No.1.
