4.1.2
Communication by LX/LY
This function is used to exchange data between the I/O master station that controls LX/LY
and another station on a one-to-one (1:1) basis.
The link input (LX) is used to receive the information input from each station in a block, and
the link output (LY) is used to send the output information of the I/O master station.
(1) Specifying the I/O master station and setting the I/O range of LX/LY
Specify the I/O master station and set the I/O range of LX/LY by the control station's
[Network range assignment] - [LX/LY settings].
Up to two I/O master stations can be set for one network (block 1 and block 2),
regardless of the status of control or normal station.
(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.
