The master station in each block for 1:1 communication using LX/LY can be specified
as I/O master station regardless of 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.
Specify the I/O master station with the "Common parameter setting" screen of the
MNETH utility if the MELSECNET/H board is control station.
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 number of
(slave) 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.
Specify the reserved station with the "Common parameter setting" screen of the
MNETH utility.
In the pairing setting, station numbers of network modules composing a redundant
CPU system can be set as pairs.
