12.2.2 Precautions when using I/O modules or intelligent function modules
(1) Compatible I/O modules
All I/O modules (QX , QY ) are compatible with the multiple CPU system.
Any of CPU No.1 to No.4 can be set as a control CPU for them.
(2) Compatible intelligent function modules
(a) When using intelligent function modules in multiple CPU system
The intelligent function modules compatible with the multiple CPU system are
those of function version B or later.
Any of CPU No.1 to No.4 can be set as a control CPU for them.
(b) Q series compatible high-speed counter modules
Q series high speed counter modules (QD62, QD62D, QD62E) compatible with
the multiple CPU system are those of function version A or later.
Any of CPU No.1 to No.4 can be set as a control CPU for them.
(c) Q series compatible interrupt modules
Q series interrupt modules (QI60) do not have a function version, however,
supports the multiple CPU system.
Any of CPU No.1 to No.4 can be set as a control CPU for them.
(3) Ranges of access to controlled and non-controlled modules
In a multiple CPU system, non-controlled modules can be accessed by setting "I/O
sharing when using Multiple CPUs" on the <<Multiple CPU setting>> tab of the C
Controller setting utility.
Refer to Section 13.4 for details of accessibility to the controlled and non-controlled
modules of the multiple CPU system.
Remark
1. The function version of the intelligent function module can be confirmed on its
rating plate.
2. Refer to Section 12.3 for the limits on the number of intelligent function
modules.
3. Refer to the manuals of the corresponding modules for how to set "I/O
sharing when using Multiple CPUs" of the programmable controller CPU and
Motion CPU.
