The Duplex System is initialized when the power supply is turned ON, when
operation is started, when the user program or PLC Setup is transferred, etc.
It involves transferring data from the active CPU Unit to the standby CPU Unit
and verifying that both CPU Units contain the same data. Duplex initialization
is performed only in Duplex Mode.
The following tables lists the items that are processed for duplex initialization
and when each item is processed.
Duplex operating status does not exist during duplex initialization (i.e., duplex
initialization is performed in simplex operating status). This means that the
