Module control with Motion CPUs
The settings required to control modules with Motion CPUs are as follows.
System configuration settings
The system configuration for Multiple CPU systems and common parameters is set in the GX Works3 [Module Configuration]
and [System Parameter].
With Motion CPUs, parameters set in GX Works3 are read by MT Developer2, and therefore the system configuration and
common parameters are not set in MT Developer2. If setting the system configuration and common parameters, always do so
with GX Works3.
Furthermore, module parameters for modules set in the system configuration are set in GX Works3, however, module
parameters for modules for which a Motion CPU has been set as the control CPU cannot be set in GX Works3.
Settings for modules controlled by Motion CPUs are specified at the MT Developer2 [Module Configuration List].
For modules used with "High-accuracy" high-speed input request signals, set the "Synchronization Setting
within the Modules" to "Use" in GX Works3, and set the fixed scan interval setting to "0.444ms" or greater.
Please note that "Synchronization Setting within the Modules" can be used for modules with 32 or less input/
output points.
System configuration setting method
■GX Works3 settings
Set the following parameters in GX Works3.
• Module configuration
• System parameter(I/O assignment setting, Multiple CPU setting, Synchronization setting)
• Set the Motion CPU as the module control CPU in "Control PLC Settings" in [I/O Assignment Setting].
■MT Developer2 settings
• Read the parameters set in GX Works3 using MT Developer2 [System Parameter Diversion].
• Select [R Series Common Parameters] [Module Configuration List] "Setting item" "Detailed" button in MT
Developer2, and then set the parameters for the module for which a Motion CPU set has been set as the control CPU in the
module detailed settings that appear.
Module individual settings
The setting items for modules for which a Motion CPU has been set as the control CPU are shown below.
Set the module settings not shown in the tables with the buffer memory for each module.
