Non-duplex Inner Boards cannot be used in either Duplex Mode or Simplex Mode.
These system configurations are possible:
Duplex System
In a Duplex System, two CS1D CPUs, two (or one) CS1D Power Supply Units, and one Duplex Unit are
mounted to a CS1D Backplane.
Simplex System
In a Simplex System, one CS1D CPU, two (or one) CS1D Power Supply Units, and one Duplex Unit are
mounted to a CS1D Backplane.
A Duplex System can be operated in either of the following two modes:
Duplex Mode
The system operates with CS1D CPUs and CS1D Power Supply Units in duplex status.
Simplex Mode
The system operates with just a single CS1D CPU. In a Simplex System, only the Simplex Mode is
possible.

Duplex One of the two CS1D CPUs actually controls operations, and the other is on
standby as a backup. The two CS1D CPUs have the same I/O memory, and
parameters (PLC Setup, I/O tables, etc.), and both run the same user's program.
Their operations differ in the following points:
The active CPU executes I/O refreshing and all event servicing.
The standby CPU handles file accessing (read only) and FINS command
execution event servicing (read only).
Operation switching Power interruptions If any of the errors listed on the left occur in the active
errors (CPU operation setting CPU, stopping operation, the standby CPU
switch: NO USE), CPU automatically switches to active status and takes over
errors, memory errors, control. At the same time, the mode is switched to

Automatic recovery After operation has been switched from Duplex Mode to Simplex Mode as a
to duplex operation result of any of the operation switching errors listed above, operation is
automatically returned to Duplex Mode when it is determined that the cause of
the error has been cleared. Automatic recovery to duplex operation must first be
enabled in the PLC Setup. (The recovery can be repeated up to ten times.)
Hardware conditions Identical models must be used for the two CS1D CPUs.
