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, QXY)

Analogue modules (Q6AD, Q6AD-, Q6DA, Q6DA-)

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.
