(2) Precautions when using Q Series I/O modules and intelligent function modules
(a) Compatible I/O modules
All I/O modules (QX , QY ) are compatible with the multiple CPU system.
They can be used by setting any of CPU No.1 to No.4 as a control CPU.
(b) Compatible intelligent function modules
1) The intelligent function modules compatible with the multiple CPU system are those of function version B or
later.
They can be used by setting any of CPU No.1 to No.4 as a control CPU.
2) Q Series high speed counter modules (QD62, QD62D, QD62E) compatible with the multiple CPU system
are those of function version A or later.
They can be used by setting any of CPU No.1 to No.4 as a control CPU.
3) Q Series interrupt modules (QI60) do not have a function version, but are supported by the multiple CPU
system.
CPUs No.1 to No.4 can be set up as control CPUs.
4) Intelligent function modules of function version A can be used in the multiple CPU system by setting CPU
No.1 as a control CPU.
However, only control CPU can be accessed from serial communication modules and other external
modules. (MELSECNET/H, serial communication modules and other external modules cannot access non-
control CPUs.)
The "SP. UNIT VER. ERR. (error code: 2150)" occurs if any of CPU No.2 to No.4 has been set as a control
CPU, and the multiple CPU system will not start up.
(c) Ranges of access to controlled and non-controlled modules
In a multiple CPU system, non-controlled modules can be accessed by setting "Out-of-group I/O setting" at the
"Multiple CPU settings" dialog box in "PLC Parameter".
Refer to Section 3.4 for the details about accessibility to the controlled and non-controlled modules in the
multiple CPU system.
When all of the following conditions 1) to 4) are met, use a MELSECNET/H module whose first five digits of serial No. is
"10042" or later.
●
A multiple CPU system containing a Built-in Ethernet port QCPU is configured.
●
To the Ethernet port of the Built-in Ethernet port QCPU, GX Developer or GOT is connected.
●
From GX Developer or GOT, access is made to another station through a MELSECNET/H module controlled by
another CPU.
●
The access target on another station is an A/QnA series CPU module.
