Interrupt Task Error Flag
(Non-fatal error)
A40213 ON when the Detect Interrupt Task Errors setting in the PLC
Setup is set to “Detect” and one of the following occurs for
the same Special I/O Unit.
FIORF(225), IORF(097) (CJ1-H-R CPU Units only),
IORD(222) or IOWR(223) in a cyclic task are competing with
FIORF(225), IORF(097), IORD(222) or IOWR(223) in an
interrupt task.
FIORF(225), IORF(097), IORD(222) or IOWR(223) was exe-
cuted in an interrupt task when I/O was being refreshed.
Note If cyclic refreshing is not disabled in the PLC Setup for
a Special I/O Unit and FIORF(225), IORF(097),
IORD(222) or IOWR(223) is executed for the same
Special I/O Unit in an interrupt task, a duplicate
refreshing status will occur and an interrupt task error
will occur.

Interrupt Task Error Cause
Flag
A42615 Indicates the cause of an Interrupt Task Error. Read-only
Interrupt Task Error, Task
Number
A42600 to
A42611
The function of these bits depends upon the status of
A42615 (the Interrupt Task Error Flag).
A42615 ON:
Contains the Special I/O Unit’s unit number when an attempt
was made to refresh a Special I/O Unit’s I/O from an inter-
rupt task with IORF(097) while the Unit’s I/O was being
refreshed by cyclic I/O refreshing (duplicate refreshing).

Basic I/O Unit Error Flag
(Non-fatal error)
A40212 ON when an error has occurred in a Basic I/O Unit (including
C200H Group-2 High-density I/O Units and C200H Interrupt
Input Units).
Read-only
Basic I/O Unit Error, Slot
Number
A40800 to
A40807
Contains the binary slot number where the error occurred
when an error has occurred in a Basic I/O Unit (including
C200H Group-2 High-density I/O Units and C200H Interrupt
Input Units).
Read-only
Basic I/O Unit Error, Rack
Number
A40808 to
A40815
Contains the binary rack number where the error occurred
when an error has occurred in a Basic I/O Unit (including
C200H Group-2 High-density I/O Units and C200H Interrupt
Input Units).
Read-only
I/O Setting Error Flag
(Fatal error)
A40110 ON when an Input Unit has been installed in an Output
Unit’s slot or vice-versa, so the Input and Output Units clash
in the registered I/O table.
Read-only
Expansion I/O Rack Number
Duplication Flags
A40900 to
A40903
The corresponding flag will be turned ON when an Expan-
sion I/O Rack’s starting word address was set from a Pro-
gramming Device and two Racks have overlapping word
allocations or a Rack’s starting address exceeds CIO 0901.
Bits 00 to 07 correspond to Racks 0 to 3.
Read-only
Too Many I/O Points Flag
(Fatal error)
A40111 ON when the number of I/O points being used in Basic I/O
Units exceeds the maximum allowed for the PLC.
Read-only
Too Many I/O Points, Details A40700 to
A40712
The three possible causes of the Too Many I/O Points Error
are listed below. The 3-digit binary value in A40713 to
A40715 indicates the cause of the error.
The number of I/O points will be written here when the total
number of I/O points set in the I/O Table (excluding Slave
Racks) exceed the maximum allowed for the CPU Unit.
The number of interrupt inputs will be written here when
there are more than 32 interrupt inputs.
The number of Racks will be written here when the number
of Expansion I/O Racks exceeds the maximum.
