Name
Scheduled Specifies the time unit to use to specify the sched-
Interrupt Inter- uled interrupt time. Set the time unit when executing
val scheduled interrupts.
The scheduled interrupt time is set using
MSKS(690).
Note CJ1-H-R and CJ1M CPU Units only.
Power OFF Interrupt
Name
Power OFF If the Power OFF Interrupt Task setting is turned ON,
Interrupt Task then a power OFF interrupt task will start if power
turns OFF.
Power OFF Power OFF is recognized when this time plus the
Detection default power OFF detection time (10 to 25 ms for AC
Delay Time power supplies and 2 to 25 ms for DC power sup-
plies) expires.
Operation
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.
Indicates whether Interrupt Task Error 1 or 2
occurred.
For error 1:
Indicates the interrupt task number.
For error 2:
Indicates the unit number of the Special I/O Unit
where the multiple I/O refreshing occurred.
