Duplex CPU Units
Duplex Errors
If an error occurs in the duplex processing itself, the mode is switched from
Duplex Mode to Simplex Mode. At that time, operation continues with the
presently active CPU Unit retaining its active status and the standby CPU Unit
remaining on standby.
Duplex errors
The above Auxiliary Area words are cleared when the mode is restored
from Simplex Mode to Duplex Mode. At that time, the contents of A023 are
transferred to A019, and the contents of A024 to A026 are transferred to
A020 to A022, as an error log.

tion errors
The time at which the mode was switched from Duplex Mode to
Simplex Mode is stored as follows:
A02400 to A02407: Second (00 to 59)
A02408 to A02415: Minute (00 to 59)
A02500 to A02507: Hour (00 to 23)
A02508 to A02515: Day (01 to 31)
A02600 to A02607: Month (01 to 12)
A02608 to A02615: Year (00 to 99)

One of the following items does not match
between the active and standby CPU Units.

Note

2.
There is no verification of Memory Card, in-
cluding installation, models, and data con-
tents, or verification of front-panel DIP
switch status. Even if any of these do not
match, operation will continue in Duplex
Mode.
The causes of duplex verification errors are
stored in the following bits of A317 in the
Auxiliary Area.
Bit 07: CPU Unit Model Verification Error
Flag
Bit 08: CPU Unit Version Verification Error
(CS1D CPU Unit Ver. 1.1 or later only)
Bit 10: Duplex Inner Board Model Verifica-
tion Error Flag (Process-control CPU Units
only)
Bit 13: Parameter Area Verification Error
Flag
Bit 14: No Active CPU Unit Error Flag
Bit 15: User Program Verification Error Flag
