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.
POINT
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.
1) A multiple CPU system containing a Built-in Ethernet port QCPU is configured.
2) To the Ethernet port of the Built-in Ethernet port QCPU, GX Developer or GOT
is connected.
3) From GX Developer or GOT, access is made to another station through a
MELSECNET/H module controlled by another CPU.
4) The access target on another station is an A/QnA series CPU module.
