4.1.1 Communication using 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 in "LB/LW Setting" of "Network Range Assignment" of the control station.
( Page 185, Section 6.3.1)
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.
