block 2.
In addition, they must be different from the actual I/O (the range of input/output
numbers to which the actual module is installed).

The master station (the control station) can be set in each block for 1:1 communication
using LX/LY regardless of the station type (either the control station or the normal
station).
Each of block 1 and block 2 has one I/O master station, which is set by the send range
(LX/LY) of each station in each block.
The reserved station designation function is used to prevent stations to be connected
in future (stations that are not actually connected but included in the total stations of a
network) from being treated as faulty stations.
The reserved stations do not affect the link scan time; they do not slow down the
network even if used as reserved stations.
In the pairing setting, set a combination of network module station numbers comprising
the redundant system.
For further information on the pairing setting, refer to Section 7.10.3.
