14.2 Precautions During Multiple PLC System Configuration
14.2.1 Function versions of High Performance model QCPU, motion CPUs and PC CPU
module that can be sued, and their mounting positions
(1) Function versions
(a) Allowable function versions and confirmation method
1) To configure a multiple PLC system, use the High Performance model
QCPU and Motion CPU of function version B.
2) To use the PC CPU module, use the following High Performance
model QCPU and Motion CPU.
• High Performance model QCPU: "03051" or later first five digits of
the serial number of function
version B
• Motion CPU: The first digits of the serial number must be as follows.
Q172CPU ....... "H" or later
Q173CPU ....... "G" or later
3) The function version of the High Performance model QCPU and Motion
CPU can be checked at the following places.
• Ratings nameplate of High Performance model QCPU and Motion
CPU
• Product data list of system monitor of GX Developer
(Refer to Section 2.3 for details.)
(b)
Operations with different function versions
Function version A High Performance model QCPUs cannot be used on a
multiple PLC system.
Errors like the ones shown in table 14.1 will be triggered and the multiple
PLC system will not start up if function version A High Performance model
QCPUs are used on a multiple PLC system.
If any of the errors shown in table 14.1 are displayed with the GX
Developer Version 6 or later PLC diagnosis function, replace the function
version A High Performance model QCPU with a function version B High
Performance model QCPU.
