4.1 Cyclic Transmission Function 4.1.11 Interlink transmission
4.1.11 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. ( Page 232, Section 6.8)
(2) An example of interlink transmission
The following is an example of interlink transmission between network No.1 and network No.2.
1. B0 turns ON on 1M
P
1.
2. By cyclic transmission, 1N
S
3 receives LB0 data.
3. The received LB0 data are transferred to LB1000 on 2M
P
1 by interlink transmission.
4. By cyclic transmission, 2N
S
2 and 2N
S
3 receive LB1000 data.
