Interlink transmission

Link device (LB/LW) data of a network module are transferred to another network module through a relay station.
Interlink transmission is executable between CC-Link IE Controller Network, MELSECNET/H and CC-Link IE Field
Network.
(1) Setting the link device transfer range
Set the link device transfer range in "Interlink Transmission Parameters" in the "MELSECNET/CC IE/Ethernet
Module Configuration" window of the relay station. (
(2) An example of interlink transmission
The following is an example of interlink transmission between network No.1 and network No.2.
