Duplex CPU System Restrictions
Standby CPU Unit
Unit version 1.0
If the standby CPU Unit is unit version
1.0 and the active CPU Unit is unit
version 2.0, a unit version of 1.0 will be
returned to the CX-Programmer.
Note The CX-Programmer checks the unit version when going online with the PLC
If duplex operation is prevented by a Duplex Verification Error, duplex opera-
tion can be recovered by stopping functions on the active CPU Unit that are
not supported by the standby CPU Unit. When a CPU Unit Version Verification
Error has occurred, the flags in A804 can be checked to identify the functions
that are not supported in the standby CPU Unit. (This function is supported by
CS1D CPU Units with unit version 1.3 or later only.)
Unit new functions can be specified from the Programming Console, by down-
loading files from a Memory Card, or by FINS write commands.
The CX-Programmer detects the unit versions of the CPU Units and allows
only functions supported by both. (The active CPU Unit compares it’s unit ver-
sion to that of the standby CPU Unit and transfers the earlier unit version to
the CX-Programmer.) It is thus not possible to specify using functions not sup-
ported by the standby CPU Unit.
or when opening any of the setting windows, such as the PLC Setup Window.
The CX-Programmer will not update the unit version following online replace-
ment of a Unit, and thus any data transfers will be performed as if the previous
unit version was still valid even if the unit version has been changed in the
online replacement procedure. After replacing a Unit online, restart the CX-
Programmer or perform another action to update the unit version information
before transferring data.
This section describes the restrictions that apply to CS1D Duplex CPU Sys-
tems.
• C200H Units (e.g., C200H Basic I/O Units, Group-2 High-density I/O
• Inner Boards cannot be mounted in CPU Units for Duplex CPU Systems.
• Memory Card functions can be executed in duplex only when the doing so
Units, and C200H Special I/O Units) cannot be used.
The only Inner Boards that can be used for Duplex CPU Systems is the
CS1D-LCP05D built into the CS1D-CPU@@PProcess-control CPU Units.
(The CS1D-LCP05D Loop Control Board cannot be ordered separately
and must be ordered as part of a CS1D-CPU@@P Process-control CPU
Unit.)
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
operation for Memory Cards, make sure that the contents and the capaci-
ties 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.

returned.
Unit version read.
The standby CPU Unit is unit
version 1.0, so the CX-Programmer
will allow using only functions
supported by unit version 1.0.
