2.5.2 Example of changing parameters on 2-tier system
The following shows examples of how to change the LB/LW network parameters when replacing the
MELSECNET (II) with MELSECNET/H.
As MELSECNET (II) has three operation modes, the examples are shown for each operation mode.
• MELSECNET mode
• MELSECNET II mode
• MELSECNET II composite mode
(1) MELSECNET mode
The following shows the procedure for changing the parameters in the case of a MELSECNET mode 2-
tier system configuration.
The MELSECNET master station is replaced with the MELSECNET/H control station, and MELSECNET
local stations are replaced with MELSECNET/H normal stations.
A MELSECNET/H module set as normal station requires network parameter setting. For replacement of
MELSECNET (II) module mounted on the CPU module of the AnN/AnA/AnSCPU (excluding
AnUS(H)CPU), newly set network parameters.
The following shows parameters required on each station of MELSECNET/H.
