Name Address Description Access Updated
PLC Setup Error Flag
(non-fatal error) A402.10 ON when there is a setting error in the PLC Setup. Read-only
PLC Setup Error Location A406 When there is a setting error in the PLC Setup, the loca-
tion of that error is written to A406 in 4-digit hexadecimal. Read-only
Name Address Description Access Updated
Too Many I/O Points Flag
(fatal error) A401.11 ON when the number of Expansion Units and Expansion
I/O Units exceeds the limit, when the number of words
allocated to these Units exceeds the limit, are mounted. Read-only
Too Many I/O Points,
Details A407.00 to
A407.12 Always 0000 hex. Read-only
Too Many I/O Points, Cause A407.13 to
A407.15
The 3-digit binary value of these bits indicates the cause
of the Too Many I/O Points Error.
010: Too many words
011: Too many Units Read-only
I/O Bus Error Flag
(fatal error) A401.14 ON in the following cases:
• When an error occurs in a data transfer between the
CPU Unit and a Expansion Unit or Expansion I/O Unit.
If this happens, 0A0A hex will be output to A404.
• When an error occurs in a data transfer between the
CPU Unit. If this happens, 0000 hex will be output to
A404 to indicate the first Unit, 0001 hex to indicate the
second Unit, and 0F0F hex to indicate an undeter-
mined Unit.
CPU Unit operation will stop and the ERR/ALM indicator
on the front of the CPU Unit will light.
(This flag will be turned OFF when the error is cleared.)
Read-only
I/O Bus Error Slot Number A404 Contains information on I/O bus errors.
The CPU Unit will stop operating and the ERR/ALM indi-
cator on the front of the CPU Unit will light.
(A401.14 (I/O Bus Error Flag) will turn ON.)
(This information will be cleared when the error is
cleared.)
0A0A hex: Expansion Unit or Expansion I/O Unit error Read-only
Duplication Error Flag
(fatal error) A401.13 ON in the following cases:
• Two CPU Bus Units have been assigned the same
unit number.
Read-only
Unit Error Flags A436.00 to
A436.05 ON when an error occurs in an Expansion Unit or Expan-
sion I/O Unit.
A436.00: 1st Unit
A436.01: 2nd Unit
A436.02: 3rd Unit
A436.03: 4th Unit
A436.04: 5th Unit
A436.05: 6th Unit
CP1W-AD041/DA041, CP1W-32ER/32ET/32ET1,
CP1W-TS002 and CP1W-TS102 are each counted as
two Units. Read-only
Number of Connected Units A437 Stores the number of Expansion Units and Expansion
I/O Units connected as a hexadecimal number.
Note This information is valid only when a Too Many
I/O Points error has occurred. CP1W-
AD041/DA041, CP1W-32ER/32ET/32ET1,
CP1W-TS002 and CP1W-TS102 are each
counted as two Units.
