N
Specify the interrupt input number.
10: Interrupt input 0

12: Interrupt input 2
13: Interrupt input 3
D
Specify either the rising or falling edge of the interrupt input sig-
nal.
0000 hex: Rising edge

N
Specify the scheduled interrupt number.
4: Scheduled interrupt 0 (interrupt task 2)
5: Scheduled interrupt 1 (interrupt task 3)
D
0000: Scheduled interrupt disabled.
0001 to 270F hex:
Scheduled interrupt interval (1 to 9999)
Note The unit for the scheduled interrupt interval can be set to
either 10 ms or 1.0 ms in the PLC Setup interrupt settings.
For the CJ1M, 0.1 ms can also be set, in which case the
time will be 0005 to 270F hex (5 to 9999).
Operand
Contents
N
Specify the scheduled interrupt number.
14: Scheduled interrupt 0 (interrupt task 2)
15: Scheduled interrupt 1 (interrupt task 3)
D
Time from start of schedule
interrupt processing or time
from previous scheduled inter-
rupt.
10-ms unit: 0 to 99,990
1-ms unit: 0 to 9,999
0.1-ms unit: 0.0 to 999.9 (CJ1M
only)
0000 to 270F hex
Note: Even if the scheduled
interrupt is currently stopped,
the time that had expired
before it was stopped can be
read. If the scheduled interrupt
has not been started at all,
0000 hex will be returned.
