(2) Link device
A link device is a data area for network module(s) to share data with the other stations on the network. Data of
each station are updated upon each link scan. Use of the link device allows for the other stations through cyclic
transmission. Link devices available for each network are listed below.

(3) Link scan and link scan time
Cyclic transmission allows for each network station to transmit data in the transmission area of the host station in
order at the defined intervals. A go-around of transmission processing by each station is called a link scan.
Transmission authority is passed to each station in each link scan. Time taken for one cycle is called the link scan
time.
For link scan, it is necessary to set network range assignment (network configuration settings) by parameters.
(4) Network range assignment (network configuration settings)
For link scan, it is necessary to set the following parameters.
Network name
CC-Link IE Controller Network
MELSECNET/H
CC-Link IE Field Network
CC-Link
Remark
If the control CPU of the network module (control station/master station) is the C Controller module, use Setting/monitoring
tools for the C Controller module to set parameters. If it is the programmable controller CPU, use GX Works2.
