5 PARAMETER SETTINGS

5.1.3 Common parameter

5 - 9
The common parameters set the LB, LW, LX and LY cyclic transmission range that allows
sending and receiving between remote master stations and remote I/O stations in a
network. Common parameter settings only need to be set for the remote master station.

(1) LX/LY settings

LX sets the remote master station (X) addresses the input the signals (X) and
sets which of the intelligent function module input reads to.
LY sets the remote I/O station output module and intelligent function module
output signal and which remote master station (Y) address to use for controlling.
Allocate LX/LY after the remote master station actual I/O. The actual I/O is the
device usage range of the input/output module and intelligent function module
that are mounted to the remote master station.
Also, set the number of remote master station points and the number of remote
I/O station points to the same number of points.
The example in the figure below shows the LX/LY range set for four remote I/O
stations.
