2.3.2 Setting items
(1) Table 2.5 lists the parameter setting items of the multiplexed remote master
station (DM
R) and multiplexed remote sub-master station (DSMR).
In the redundant system, the same network parameters are set to both the
control and standby systems. For this reason, parameter setting for the
multiplexed remote sub-master station is not required.
Make sure to assign No.0 to the master module mounted on the system A CPU
in the redundant system.
