CHAPTER6 PARAMETER ADDED FOR MULTIPLE CPU

6.1 Parameter list

(1) Parameters that enable the use of multiple CPU system
Comparing with a single CPU system, a multiple CPU system has additional settings of "Multiple CPU settings" in
PLC parameter and "Control PLC" setting in I/O assignment setting.
The same PLC parameter must be set to all the CPU modules used in the multiple CPU system, except some
settings.
When using a PC CPU module, reuse the multiple CPU system parameters in the PC CPU setting utility.
PC CPU module manual
(2) The PLC parameter settings for use in multiple CPU system
The necessity of setting PLC parameter and necessity of same setting that are required for using multiple CPU
system are listed in Table6.1 and 6.2.
When parameters such as multiple CPU settings have been changed, make the same settings for all CPUs in the
multiple CPU system, then reset CPU No.1 or reapply power to the multiple CPU system (power ON to OFF to
ON).
It is possible to reuse the multiple CPU parameters set up for another project with GX Developer.
(Refer to Section 8.2.1 (4) and Section 8.2.2 (4) for reuse of the multiple CPU parameters.)
(a) For Basic model QCPU, High Performance model QCPU and Process CPU
The Table6.1 shows the PLC parameter settings that are required when the Basic model QCPU, the High
Performance QCPU and the Process CPU are used.
