Precautions
■Modules supporting interlink transmission
Relevant modules are as follows.
• RJ71GN11-T2 (master station)
• CC-Link IE Controller Network-equipped module (control station, normal station)
• CC-Link IE Field Network-equipped module (master station, submaster station).
• RJ71LP21-25 (control station, normal station)
■Transfer destination link device setting
Do not use link devices set for link refresh range as a transfer destination. If doing so, transfer destination link devices will be
overwritten by link refresh. To use transfer destination link device data in the CPU module, set the transfer source link device
as the link refresh range.
CPU module
Link refresh
range 1
Link refresh
range 2
■Setting 65 or more interlink transmission ranges
Use link direct devices in a program to perform interlink transmission.
Ex.
The following shows an example of performing interlink transmission between the master station on Network No.1 (CC-Link
IE Field Network) and the normal station on Network No.2 (MELSECNET/H Network).

Copied with the MOV instruction.
(1) The link direct device cannot be specified for both the first and second arguments. Use link refresh for either of the argument to specify the CPU device.
■Performing interlink transmission in a multiple CPU system
When different control CPUs are set for the network modules, interlink transmission cannot be performed using interlink
transmission parameters or a program. Perform interlink transmission using data communication by the CPU buffer memory.
