The followings are available when selecting the method of setting devices with each CPU optionally.
• The order of the send range for each module can be changed, since devices can be set individually.
• The system scan time can be reduced, since it is possible to set for not performing unnecessary refresh.

The following shows the example performing auto refresh between High Performance model QCPU of CPU
