Address
A40214
ON: One of the following errors occurred: Duplex
verification error, duplex bus error, duplex power
supply unit error, or duplex communications error
(See note.)
A31600
ON: An inconsistency exists between the program
or memory of the active and standby CPU Units in
Duplex Mode. (Refer to A317, A804 for details.)
A31601
ON: An error occurred on the sync transfer bus in
the duplex system.
A31602
ON: An error occurred in the Power Supply Unit or
power supply system on a duplex CPU Rack,
Expansion Rack, or Long-distance Expansion
Rack.
A31603
ON: One of the duplex Communications Units has
failed. (Refer to A434 to A437 for details.)
Note Duplex CPU Systems only.
Address
A31600
ON: An inconsistency exists between the program or mem-
ory of the active and standby CPU Units in Duplex Mode.
(Refer to A317, A804 for details.)
A31706
ON: A duplex error occurred in the other CPU Unit when
entering Duplex Mode.
A31707
ON: The CPU Units were not the same model when entering
Duplex Mode.
A31708
ON: The unit version of the standby CPU Unit is earlier than
the unit version of the active CPU Unit and the active CPU
Unit uses function not supported by the standby CPU Unit.
A31710
ON: The duplex Inner Boards in the two Process-control
CPU Units were not the same model when entering Duplex
Mode.
A31713
ON: The parameter area in the two CPU Units in duplex
mode do not have the same contents.
ON: There is no active CPU Unit for CPU Unit set for
standby operation when power was turned ON in duplex
mode. This occurs when one of the following is detected:
The active CPU Unit is not mounted, the CPU Unit switch is
set to NO USE, or pin 7 on the DIP switch is set for simple
backup operation.
A31715
ON: The user program in the two CPU Units in duplex mode
do not have the same contents.
A80400
ON: The unit version of the standby CPU Unit is earlier than
the unit version of the active CPU Unit and the active CPU
Unit uses a PLC Setup setting (Ethernet Duplex Setting) that
is not supported by the standby CPU Unit.
A80401
ON: The unit version of the standby CPU Unit is earlier than
the unit version of the active CPU Unit and the active CPU
Unit uses a PLC Setup setting (Unit Removal without a Pro-
gramming Device Function Setting) that is not supported by
the standby CPU Unit.
