Other PLC Operating Information
Duplication Error Flag
(fatal error) A401.13 ON in the following cases:
• Two CPU Bus Units have been assigned the same unit
number.
• Two Special I/O Units have been assigned the same
unit number.
Read-only
CPM1A Unit Error Flags A436.00 to
A436.06 ON when an error occurs in a CPM1A Expansion Unit or
Expansion I/O Unit.
A436.00: 1st Unit
A436.10: 2nd Unit
A436.02: 3rd Unit
A436.03: 4th Unit
A436.04: 5th Unit
A436.05: 6th Unit
A436.06: 7th Unit
Note CPM1A-TS002 and CPM1A-TS102 are each
counted as two Units.
Read-only
Number of Connected
CPM1A Units A437 Stores the number of CPM1A Expansion Units and
Expansion I/O Units connected as a hexadecimal num-
ber.
Note This information is valid only when a Too Many
I/O Points error has occurred. CPM1A-TS002 and
CPM1A-TS102 are each counted as two Units.

CPU Bus Unit Number
Duplication Flags A410.00 to
A410.15 The Duplication Error Flag (A401.13) and the corre-
sponding flag in A410 will be turned ON when an CPU
Bus Unit’s unit number has been duplicated. Bits 00 to 15
correspond to unit numbers 0 to F. Read-only
CPU Bus Unit Error, Unit
Number Flags A417.00 to
A417.15 When an error occurs in a data exchange between the
CPU Unit and an CPU Bus Unit, the CPU Bus Unit Error
Flag (A402.07) is turned ON and the bit in A417 corre-
sponding to the unit number of the Unit where the error
occurred is turned ON. Bits 00 to 15 correspond to unit
numbers 0 to F. Read-only
CPU Bus Unit Error Flag
(non-fatal error) A402.07 ON when an error occurs in a data exchange between
the CPU Unit and an CPU Bus Unit (including an error in
the CPU Bus Unit itself). Read-only
Name Address Description Access Updated
Special I/O Unit Number
Duplication Flags A411.00 to
A416.15 The Duplication Error Flag (A401.13) and the corre-
sponding flag in A411 through A416 will be turned ON
when a Special I/O Unit’s unit number has been dupli-
cated.
Bits A411.00 to A416.15 correspond to unit numbers 000
to 05F (0 to 95).
Read-only
Special I/O Unit Setting
Error Flag
(non-fatal error) A402.06 ON when an error occurs in a data exchange between
the CPU Unit and a Special I/O Unit (including an error in
the Special I/O Unit itself). Read-only
Special I/O Unit Error, Unit
Number Flags A418.00 to
A423.15 When an error occurs in a data exchange between the
CPU Unit and a Special I/O Unit, the Special I/O Unit
Error Flag (A402.06) will be turned ON. Read-only
Name Address Description Access Updated
Battery Error Flag
(non-fatal error) A402.04 ON if the CPU Unit’s battery is disconnected or its volt-
age is low and the Detect Battery Error setting has been
set in the PLC Setup. Read-only
Cycle Time Too Long Flag
(fatal error) A401.08 ON if the cycle time exceeds the maximum cycle time set
in the PLC Setup (the cycle time monitoring time). Read-only
FPD Teaching Bit A598.00 Turn this bit ON to set the monitoring time automatically
with the teaching function. Read/write
Memory Corruption
Detected Flag A395.11 ON when memory corruption is detected when the power
supply is turned ON. Read-only
