For each block, set an I/O master station and I/O ranges used in the LX/LY communication
between the I/O master and relevant stations.
Set [LX/LY settings (1)] as block 1, and [LX/LY settings (2)] as block 2.
Refer to the following for communication by LX/LY.
Section 4.1.2 Communication by LX/LY
M station: I/O master station, L station: Other station
* 1 The LX/LY data of the same I/O numbers with the actual I/O (the range where actual modules are
mounted) must be refreshed to the area after the actual I/O area or to any other than LX/LY by
refresh parameters.
Transfer target CPU-side devices in refresh parameters cannot overlap with the actual I/O areas.
