4.1.1
Communication by LB/LW
This function allows each station to write data to its own send range area of a link device
(LB/LW) to send them to all other stations on the network.
The link relay (LB) and link register (LW) can send/receive the ON/OFF information and
16-bit data respectively.
(1) Setting each station's send range in LB/LW
Set each station's send range in LB/LW by the control station's [Network range
assignment] - [LB/LW settings].
Note that any other area than the own station's send range in LB/LW is the area for
the data received from other stations.
(2) Setting the link refresh range
Set the range of the transfer between the link devices of the CC-Link IE controller
network module and CPU module devices.
