1 OVERVIEW
1.4.3 Precautions for using Q series I/O modules and intelligent function modules
(1) Modules controllable by the Motion CPU
I/O modules (QX , QX -S1, QY , QH , QX Y , Q6 AD , Q6 AD- ,
Q6
DA , Q6 DA- ), interrupt module (QI60) and motion modules (Q172LX,
Q172EX, Q173PX) can be controlled by the Motion CPU.
(2) Compatibility with the Multiple CPU system
(a) All I/O modules (QX , QX -S1, QY , QH , QX Y , Q6 AD ,
Q6
AD- , Q6 DA , Q6 DA- ) support the Multiple CPU system.
(b) The interrupt module (QI60), which is currently not subject to function
upgrade, supports the Multiple CPU system.
(c) The intelligent function modules support the Multiple CPU system only when
their function version is B or later. These modules cannot be controlled by
the Motion CPU, so be sure to use the PLC CPU as a control CPU.
(d) All motion modules (Q172LX, Q172EX, Q173PX) support the Multiple CPU
system. These modules cannot be controlled by the PLC CPU, so be sure to
use the Motion CPU as a control CPU.
(3) Access range from a non-control 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 a non-control 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 "Q173CPU(N)/Q172CPU(N) User's Manual" for the model name
which can be controlled by the Motion CPU.
