Applications When a constant monitoring system, such as a PT or personal computer appli-
constantly cation, is connected to the CPU Unit's RS-232C port, an RS-232C/RS-422
connected to Adapter can be used to connect to both the active and standby CS1D CPU
RS-232C port Units.

Restrictions When writing to a Memory Card, the same data is written to not only the Memory
on Memory Card mounted in the active CPU Unit, but also to the one mounted in the
Card func- standby CPU Unit.

on the Memory Cards mounted in the active and standby CPU Units even
if the data is not the same. Therefore, before enabling duplex operation
for Memory Cards, make sure that the contents are the same for both of
the Memory Cards.
Note When EM File Memory is set for duplex operation, processing is exe-
cuted to match the contents of EM File Memory in both CPU Units. It is
not necessary to enable duplex operation for Memory Cards in the PLC
Setup.
