ON in the following cases:
1) An interrupt task longer than 10 ms was exe-
cuted during I/O refreshing with a C200H Special
I/O Unit or Remote I/O Slave Rack. (CS Series
only)
2) Interrupt Task Error Detection is enabled in the
PLC Setup, and one of the following conditions
occurs for the same Special I/O Unit.
• There is a conflict between an IORF(097),
FIORF(225) (CJ1-H-R only), IORD(222), or
IOWR(223) instruction executed in the inter-
rupt task and an IORF(097), FIORF(225) (CJ1-
H-R only), IORD(222), or IOWR(223) instruc-
tion executed in the cyclic task.
• There is a conflict between an IORF(097),
FIORF(225) (CJ1-H-R only), IORD(222), or
IOWR(223) instruction executed in the inter-
rupt task and the CPU Unit’s I/O refreshing
(END refreshing).
Note When a Special I/O Unit’s Cyclic Refresh-
ing is enabled in the PLC Setup, and an
IORF(097), FIORF(225) (CJ1-H-R only),
IORD(222), or IOWR(223) instruction is
executed for the same Special I/O Unit,
there will be duplicate refreshing and an
Interrupt Task Error will occur.
