Address
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.
A42615
Indicates the cause of an Interrupt Task Error.
A42600 to
The function of these bits depends upon the status of
A42611
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).
Address
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).
A40800 to
Contains the binary slot number where the error occurred
A40807
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).
A40808 to
Contains the binary rack number where the error occurred
A40815
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).
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.
A40900 to
The corresponding flag will be turned ON when an Expan-
A40903
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.
A40111
ON when the number of I/O points being used in Basic I/O
Units exceeds the maximum allowed for the PLC.
A40700 to
The three possible causes of the Too Many I/O Points Error
A40712
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.
