(2) LB/LW setting

The LB/LW data on each remote I/O station are transferred to the CPU module
via LB/LW of the remote master station for control in the CPU module.
In the LB/LW setting, set the area ranges for sending data from the remote
master station to each remote I/O station and for receiving data from each
remote I/O station to the remote master station.
In addition, if intelligent function parameters (automatic refresh setting) are set to
an intelligent function module on a remote I/O station from GX Configurator, the
buffer memory of the intelligent function module can be read/written from the
remote master station using LW.
For details, refer to Section 3.2.1.
REMARKS
The link device (LB, LW) data of the remote master station are refreshed to the
internal user devices (e.g. B, W) of the CPU module to be used in sequence
programs.
For details of the link refresh, refer to Section 5.1.5.
