2.1.2 System configuration using High Performance model QCPU or Process CPU as CPU No.1
POINT
When the multiple CPU system is configured using the High Performance model
QCPU as the CPU No.1, only the following CPU modules can be used as the
CPUs No.2 and 3.
• High Performance model QCPU
• Universal model QCPU (except Q02UCPU)
• C Controller module

Diagram 2.12 System configuration example for using Q3 SB
• The slim type main base unit has no extension cable connector.
The extension base unit and GOT cannot be bus-connected.
• Since the current consumption of the CPU module exceeds the rated output
current of the power supply module (Q61SP), mounting 4 CPU modules is not
allowed.
• When using the C Controller module, mounting three CPU modules is not
allowed.
• "No. of CPUs" indicates the number of CPU modules set in the "No. of PLCs" of
the GX Developer.
