*1 In CC-Link Ver.1, increasing the number of occupied stations can increase the number of link points per station.
In CC-Link Ver.2, increasing the number of occupied stations and setting the greater value in the expanded cyclic setting
can increase the number of link points per station.
For the points, refer to the following table.
