6.1.1 Overview of PLC Link Operation

 "Link relays (L)" and data registers "link registers (LD)" are shared between the connected
PLCs.
 If the link relay contact for one PLC goes on, the same link relay also goes on in each of the
other PLCs connected to the network.
 Likewise, if the contents of a link register are rewritten in one PLC, the change is made in the
same link register of each of the other PLCs connected to the network.
