5 PARAMETER SETTINGS
5.1.3 Common parameter
The common parameters set the LB, LW, LX and LY cyclic transmission ranges that
allows sending and receiving between a remote master station and remote I/O stations in
a network. Common parameters only need to be set for the remote master station.
(1) LX/LY setting
I/O signals (X, Y) of each remote I/O station are transferred to the CPU module
via link devices (LX, LY) of the remote master station for control in the CPU
module.
The I/O signals (X, Y) are assigned to the remote master station's link devices
(LX, LY) in the LX/LY setting.
The LX setting is made for transferring the input signal (X) information of remote
I/O stations to the link devices of the remote master station.
The LY setting is made for transferring the link device (LY) information of the
remote master station to the output signal (Y) area of the remote I/O stations.
Set the same device points for the remote master and each remote I/O station in
the LX/LY setting.
