Reducing startup time when power is turned ON
Automatically returning to Duplex Mode after switching to
Simplex Mode (continuing operation in Duplex Mode with a
CPU Unit in which an operation switching error has
occurred)
Starting operation if either of the CPU Units is normal when
the power is turned ON.
Using the RS-232C port on the standby CPU Unit to inde-
pendently (i.e., independent from the active CPU Unit’s
serial port) monitor operation via an RS-232C cable (write
operations not allowed)
Reducing the increase in the
cycle time when initializing
duplex operation
Setting duplex operation for Memory Cards (See note 3.)
Removing a Unit that is operating without using the CPU
Unit’s Programming Device
Making I/O bus errors due to Unit failure non-fatal errors
Replacing a Unit during operation without using the CPU
Unit’s Programming Device
Setting I/O bus errors as non-fatal errors when they are
caused by a Unit failure
Turning ON the following Special I/O Unit Error, Unit Num-
ber Flags and when a Special I/O Unit or CPU Bus Unit
Error, Unit Number Flags during online Unit replacement.
Special I/O Units: A41800 to 42315
CPU Bus Units: A41700 to 41715

Overview of PLC Setup
Duplex System Settings
Note
Using CPU Units containing
the same program
Not using the EM Area in the
user program, data links, etc.
The PLC Setup contains basic CPU Unit software settings that the user can
change to customize PLC operation. These settings can be changed from a
Programming Console or other Programming Device. The various settings for
the CPU Unit are made in the PLC Setup.
The following table lists cases in which the PLC Setup must be changed for
Duplex Systems.
1. Duplex CPU Systems only.
2. CS1D CPU Unit Ver. 1.1 or later and CX-Programmer version 4.0 or later
3. CX-Programmer version 3.1 or higher.
4. This function is supported only by Duplex CPU Units with Unit Ver. 1.2 or
only.
later and CX-Programmer version 6.1 or higher.

PLC Setting(s) to be changed
Run under Duplex Initial
(under Operation Settings)
Return Automatically (under
Operation Settings)
• Run under Duplex Initial
• When an operation switch-
Allow STB-COMM
Transfer Program
• Transfer EM
• Division Size
Enable Memory Card Duplex
Setting
Allow removing Units with-
out support software
Enable removal/addition of
units without support soft-
ware
When removing any special
unit, turn ON the error unit
flag
(under Operation Settings)
ing error occurs in the
Active CPU Unit, the
Standby CPU Unit will
become the Active CPU
Unit and start operating
