4.6 Settings from GX Developer
To use the Ethernet module, parameters must be previously set from GX Developer.
For the parameter settings of each assignment in this textbook, refer to the parameter
settings of each assignment (Chapter 5 to 8).
For details of each screen, refer to the GX Developer Operating Manual and Q
Corresponding Ethernet Module User's Manual.
To perform the parameter setting using this textbook, GX Developer Version 8 or later
is required. (This textbook uses GX Developer Version 8 to explain.)
(1) Multiple CPU setting
The settings for the No. of PLC, Operating mode, Refresh settings, etc. are
performed to configure the multiple CPU system. Always make this setting when
using the multiple CPU system.
For the operation prior to displaying the multiple CPU settings screen, refer to
Section 5.2.1.
REMARK
As the demonstration machine used in this textbook has two CPUs installed for the
multiple CPU configuration, setting PLC parameters for the multiple CPU system is
required.
For the setting of the multiple CPU system, this textbook uses default values for the
parameters (setting of control CPU, etc.) other than the following.
