The link refresh is executed between the refresh data storage area and the driver
buffer.
In order to execute the link refresh, set the link refresh cycle and the refresh
parameters in the CC IE Control utility.
(a) Concept of refresh range (points)
Within the range set on the "Refresh parameter setting" screen of the CC IE
Control utility, the range set by the network range assignment is refreshed.

The range from the first to the last addresses is set as the initial setting of the
refresh parameter. (Clicking the Default button on the "Refresh parameter setting"
screen of the CC IE Control utility resets the setting to the initial setting.)
