Error Processing
Duplication Verification Errors (Duplex CPU Systems Only)
The DPL STATUS indicators are flashing red.
DLP verification error (to Simplex Mode)
Check the following bit in A317
channel of the standby CPU using
the peripheral tool.
14: Active CPU missing bit
OFF
Check the following
bits in A317 using the Support Software.
07: CPU Unit Model Verification Error Flag
10: Duplex Inner Board Model Verification Error
Flag
Both bits are OFF
Check the following bit in A317 using the
Support Software.
08: CPU Unit Version Verification Error
Flag
OFF
Check the following
bit in A317 using the Support Software.
13: Parameter Area Verification Error Flag
15: User Program Verification
Error Flag
Either bit is ON
Press the Initial Switch.
DPL STATUS indicators still flashing red?
Flashing red
Transfer the user program and parameter
area (PLC setup, I/O tables, etc.) to the active
CPU Unit from the Support Software.
DPL STATUS indicators still flashing red?
Flashing red
Replace the DPL Unit.

ON
The active CPU Unit is not
mounted, or the use active
CPU setting switch is set to
NO USE
Yes
Set the use active CPU switch to NO USE,
mount the active CPU Unit (or check the
mounting), and set the use active CPU switch
to USE.
Next, press the initial switch on the DPL unit.
Either bit
is ON
Turn OFF the Standby CPU Unit operation setting switch.
Replace the standby CPU Unit so that the CPU
Unit models are the same.
For CS1D-CPU67HA, check the settings of the
DIP switches, and ensure that the model set in
the internal mode is the same as another CPU
Unit model.
Turn ON the Standby CPU Unit operation setting switch.
Replace the standby CPU Unit with a CPU
ON
Unit that has a unit version that is the same or
later than the active CPU Unit. Alternatively,
delete functions from the active CPU Unit that
cannot be executed by the standby CPU Unit.
Both bits
are OFF
Transfer the user program and parameter
area (PLC setup, I/O tables, etc.) to the active
CPU Unit from the Support Software.
OFF
Error occurs in standby CPU
NO
OFF
Operation will restart in Duplex Mode.
No
The active CPU Unit has
simple backup (reading
from the memory card to the
CPU unit) set.
Yes
Cancel the simple backup setting (reading from
the memory card to the CPU Unit) on the
active CPU Unit.
Turn the power of the PLC Unit OFF and then
ON, and press the initial switch on the DPL
Unit.
Set the use active CPU setting switch
to NO USE, and then correct the DIP
switch setting on the active CPU (refer
to 2-4-2 Components).
Set the use active CPU setting switch
to USE, and then press the initial
switch on the DPL Unit.
YES
Reset the error in standby CPU.
