(fatal error)
I/O Bus Error Slot Number
628
Address
A402.10
ON when there is a setting error in the PLC Setup.
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.
Address
A402.13
ON when the Detect Interrupt Task Errors setting in the
PLC Setup is set to "Detect" and an interrupt task is exe-
cuted for more than 10 ms during I/O refreshing of a
Special I/O Unit.
This flag will also be turned ON if an attempt is made to
refresh a Special I/O Unit's I/O from an interrupt task with
IORF(097) while the Unit's I/O is being updated by cyclic
I/O refreshing (duplicate refreshing).
A426.15
When A402.13 (the Interrupt Task Error Flag) is ON, this
flag indicates the cause of the error.
A426.00 to
When A402.13 (the Interrupt Task Error Flag) is ON, con-
A426.11
tains the unit number of the Special I/O Unit for which
duplicate refreshing was executed.
Address
A401.11
ON when the number of CP-series Expansion Units and
Expansion I/O Units exceeds the limit, when the number
of words allocated to these Units exceeds the limit, or
when too many CJ-series Units are mounted.
Always 0000 hex.
A407.12
The 3-digit binary value of these bits indicates the cause
A407.15
of the Too Many I/O Points Error.
010: Too many CP-series words
011: Too many CP-series Units
111: Too many CJ-series Units
A401.14
ON in the following cases:
• When an error occurs in a data transfer between the
CPU Unit and a CP-series Expansion Unit or Expan-
sion 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 and a CJ-series 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 undetermined Unit.
• When the End Cover is not attached to the last CJ-
series Unit. If this happens, 0E0E hex will be output to
A404.
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.)
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.
(A401.04 (I/O Bus Error Flag) will turn ON.)
(This information will be cleared when the error is
cleared.)
0A0A hex: CP-series Unit error
0000 hex: CJ-series Unit error, 1st Unit
0001 hex: CJ-series Unit error, 2nd Unit
0F0F hex: CJ-series Unit error, unknown Unit
0E0E hex: CJ-series Unit error, no End cover
