5.
Network construction
Set network parameters in "Module Parameter (Network)" of the engineering tool.
• Set a slave station for Network Configuration Settings.
Devices of the station No.1 to 32 and slave stations which support the motion mode (stations selected to "Motion Mode" in
"Station-specific mode setting" when the MR-J4-GF is used) are used as the axis 1 to 32.
For details, refer to the following.

6.
Module setting (module extended parameter)
Configure the setting related to axis control in "Module Extended Parameter" of the engineering tool.
For details, refer to the following.
MELSEC iQ-R Simple Motion Module User's Manual (Application)
7.
Auto refresh setting
Set the link refresh settings in "Basic Settings" of Module Parameter (Network).
For details, refer to the following.
MELSEC iQ-R Simple Motion Module User's Manual (Network)
Set the refresh setting for monitor data of axis control in Module Parameter (Motion).
For details, refer to the following.
MELSEC iQ-R Simple Motion Module User's Manual (Application)
8.
Programming
Create programs.
For details, refer to the following.
Page 72 List of labels to be used
Note the following when using the inter-module synchronization function.
• Always create an inter-module synchronous interrupt program (I44) and enable interrupt (EI instruction). If a sequence
program does not include "I44" or "EI", I/O signals (X/Y) of the RD77GF may not be refreshed. Even when control of the
RD77GF does not need to be synchronized with the inter-module synchronization cycle, create an empty inter-module
synchronous interrupt program (I44).
For details, refer to the following.

9.
Writing parameters
Write the set parameters and programs to the CPU module.
• "Simple Motion Module" or "CPU module (including an SD memory card inserted into the CPU module)" can be selected as
a parameter storage location of module extended parameters. The initial setting is "Simple Motion Module". When writing
module extended parameters, specify the same storage location in the writing destination of the engineering tool as
"Module extended parameter storage location setting" in "Module operation setting" of Module Parameter (Motion).
For details, refer to the following.
MELSEC iQ-R Simple Motion Module User's Manual (Application)
10.
Network diagnostics
Using network diagnostics, check if the cables are connected properly and communication are performed normally with the
configured parameters.
For details, refer to the following.
