2 MULTIPLE CPU SYSTEM
2.1.3 Precautions for using I/O modules and intelligent function modules
(1) Modules controllable by the Motion CPU
Modules controllable by the Motion CPU are shown below.
• Motion modules (Q172DLX, Q172DEX, Q173DPX)
• I/O modules (QX , QY , QH , QX Y )
• Analogue modules (Q6 AD , Q6 AD- , Q6 DA , Q6 DA- )
• Interrupt module (QI60)
(2) Compatibility with the Multiple CPU system
The intelligent function modules of function version "B" or later support the
Multiple CPU system. Be sure to use the PLC CPU as a control CPU because of
the intelligent function modules cannot be controlled by the Motion CPU.
(3) Access range from non-controlled CPU
(a) The Motion CPU can access only the modules controlled by the self CPU. It
cannot access the modules controlled by other CPUs.
(b) Access range from non-controlled PLC CPU for the modules controlled by
the Motion CPU are shown below.

REMARK
• The function version of an intelligent function module can be checked on the rated
plate of the intelligent function module or in the GX Developer's system monitor
product information list.
• Refer to the "Q173DCPU/Q172DCPU User's Manual" for the model name which
can be controlled by the Motion CPU.
