Precautions when Connecting Programming Devices to Duplex
CPU Systems
Note
This section describes factors that must be taken into account when connect-
ing a CX-Programmer or a Programming Console to a CS1D Duplex System.
With a Duplex CPU System, Programming Devices must be connected to a
serial communications port (peripheral port or RS-232C port) of the active
CPU Unit.
1. If connected to the peripheral port of the standby CPU Unit, no writing can
2. If connected to the RS-232C port of the standby CPU Unit, neither reading
With a Duplex CPU Systems, communications will become possible if the CX-
Programmer is left connected constantly only to the active CPU Unit, and an
operation switching error occurs causing the active CPU Unit to become the
standby CPU Unit.
For that reason, if the CX-Programmer is to be left connected, or if it is prefer-
able to not have to reconnect the cable to the other CPU Unit when a switch-
ing error occurs, it is recommended that the following connection be used. For
this, it is required that the Standby CPU Unit RS-232C Port Setting in the PLC
Active CPU Unit
be executed from either the CX-Programmer or the Programming Console.
Only reading is enabled. (The CX-Programmer cannot be used for opera-
tions such as changing operating modes, transferring user programs,
transferring PLC Setup settings, changing I/O memory, creating and trans-
ferring I/O tables, performing online editing, and changing timer/counter
settings.)
nor writing can be executed from the CX-Programmer. Reading only, how-
ever, can be enabled by means of the Standby CPU Unit RS-232C Port
Setting in the PLC Setup.

Connect to peripheral port
or RS-232C port of active
CPU Unit.
When connected to the peripheral port,
write operations cannot be executed.
Only read operations are enabled.
When connected to the RS-232C port, and
with the default settings in the PLC Setup,
both reading and writing are disabled.
