When an error occurs in the active Communications
Unit and operation is switched to the standby
Communications Unit, an error code will be stored to
show the cause of the error in the active
Communications Unit. (See note.) The code is set to
00 Hex if online replacement is performed for the

the I/O tables while this flag is ON, an I/O table
generation error will occur and the I/O tables will not
be created.

attempt is made to generate the I/O tables while this
flag is ON, an I/O table generation error will occur and
the I/O tables will not be created.
ON: A Duplex Communications Unit is missing or
the mounted Unit does not support duplex
operation.
OFF: I/O table creation completed normally.
The corresponding bit in A434 will also turn ON.
Turns ON when the unit numbers or node addresses
of two Units specified as a pair of Duplex
Communications Units in the PLC Setup do not
