Note
A Duplex CPU System consists of two CPU Units for Duplex CPU Systems
and one Duplex Unit mounted to a CS1D Backplane for Duplex CPU Sys-
tems.
1. A Duplex CPU System must be used for Duplex CPU Unit operation. Du-
2. Inner Boards cannot be mounted in CPU Units for Duplex CPU Systems.
3. Memory Card functions can be executed in duplex only when the doing so
4. EM file memory is configured in duplex between the two CPU Units.
A Duplex CPU System can be operated in either Duplex Mode or Simplex
Mode.

is enabled in the PLC Setup. No processing, however, is executed during
duplex initialization to match the data on the Memory Cards mounted in the
active and standby CPU Units. Therefore, before enabling duplex opera-
tion for Memory Cards, make sure that the contents and the capacities are
the same for both of the Memory Cards. If the free space or the contents
are different, write processing to the Memory Cards may not be completely
correctly.

can also be checked by means of A32808 in the Auxiliary Area (ON:
Duplex Mode, OFF: Simplex Mode).

In Duplex Mode, two CPU Units (active and standby) operate
in a duplex configuration. When an error causing operation to
switch to the standby occurs, the standby CPU Unit automati-
cally switches to active status.
In Simplex Mode, a single CPU Unit controls operations inde-
pendently. The Duplex System goes into Simplex Mode either
as a result of an error causing operation to switch to the
standby while in Duplex Mode or when Simplex Mode is
selected using the Mode Setting Switch.
