Link Specifications

2.2.1 Link patterns and number of link points in each FX Series
The number of occupied link points varies depending on the number of slave stations used.
For example, when three slave stations are connected in "Pattern 1", M1000 to M1223 and D0 to D33 are
occupied, and unoccupied devices can be used as general devices for control.
(Link devices for unconnected slave stations can be used as general devices for control, but it is
recommended to leave them in the unoccupied status if slave stations may be added in the future.)
