Error
Operation will continue for any of the following errors for a Duplex CPU Sys-
tem in Duplex Mode or in Simplex Mode, or for a Single CPU System. For
some of these errors, operation for a Duplex CPU System will switch from
Duplex Mode to Simplex Mode and for other errors, operation will remain in
Duplex Mode. These are listed separately below.
Connect the CX-Programmer or a Programming Console to display the error
message (in the PLC Error Window on the CX-Programmer). The cause of
the error can be determined from the error message and related Auxiliary
Area flags and words.
For a Duplex CPU System, duplex errors will cause operation to be switched
to Simplex Mode, but operation will continue in RUN or MONITOR mode.
A non-fatal duplex error has occurred if the indicators have the following con-
ditions during operation in RUN or MONITOR mode.
Duplex errors are unique to Duplex CPU Systems and will not occur on Single
CPU Systems.
For all of the following errors, operation will continue if the error occurs in
Duplex Mode or in Simplex Mode. If it occurs in Duplex Mode, operation will
switch to Simplex Mode.

Check the items to the left between
the two CPU Units and be sure they
are the same and then toggle the
power supply.
If the problem persists, retransfer the
user program and parameter area
data (including the PLC Setup CPU
Bus Unit settings and I/O tables) to the
active CPU Unit.
If the problem persists, replace the
Duplex Unit.
Prepare the system to stop operation
and then press the initialization button
on the Duplex Unit.
If the problem persists, replace the
Duplex Unit.
