Precautions
■Stations supporting interlink transmission
Interlink transmission parameters can be set for the master station and submaster station.
■Modules supporting interlink transmission
The master station and submaster station can perform interlink transmission with the following modules.
• CC-Link IE Controller Network-equipped module (control station, normal station)
■Transfer destination link device setting
Do not use link devices set for link refresh range as a transfer target. If doing so, transfer target link devices will be overwritten
by link refresh. To use transfer target link device data in the CPU module, set the transfer source link device as the link refresh
range.
■Setting 65 or more interlink transmission ranges
Use link direct devices in a program to perform interlink transmission.
■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.
