Note If high-speed interrupt function is enabled for a CJ2 CPU Unit with unit version 1.1 or later, an error will not occur and the
Error Flag will remain OFF even if the time unit is set to 0.1 ms for scheduled interrupt 0 (N = 4).

The scheduled interrupt time is set using MSKS(690).
CS/CJ/NSJ Series Instructions Reference Manual (W474)
0 decimal (0000 hex):
Disable interrupt. (Stop internal timer.)
1 to 9,999 decimal (0001 to 270F hex):
Enable interrupt. (Reset internal timer value, and then start the timer with an interrupt interval
between 10 and 99,990 ms.)
1 to 9,999 decimal (0001 to 270F hex):
Enable interrupt. (Reset internal timer value, and then start timer with an interrupt interval
between 1 and 9,999 ms.)
5 to 9,999 decimal (0005 to 270F hex):
Enable interrupt. (Reset internal timer value, and then start timer with interrupt interval between
0.5 and 999.9 ms.)
Note Settings 0001 to 0004 cannot be used. An error will occur if one of these settings is used.
CJ2M CPU Units
4 to 9,999 decimal (0004 to 270F hex): Enable interrupt. (Start internal timer with interrupt
interval between 0.4 and 999.9 ms.)
Note Settings 0001 to 0003 decimal (0001 to 0003 hex) cannot be used. An error will occur if
one of these settings is used.

• ON if N is not within the specified range (0 to 15 for the CJ1M CPU Unit, 0 to 15, 100 to 107, or 110 to
117 for the CJ2M CPU Unit; and 0 to 5 for other CPU Units). Errors when specifying I/O Interrupts:
• When using C200HS-INT01 interrupt inputs, the Error Flag will go ON if C is not between 0000 and
00FF hex.
• When using the CJ1M or CJ2M CPU Unit's built-in interrupt inputs, the Error Flag will go ON if C is
not between 0 and 3. Errors when specifying Scheduled Interrupts:
• When the time units are set to 10 ms or 1 ms, the Error Flag will go ON if C is not between 0 and
9,999 decimal (0000 to 270F hex).
• When using a CJ1M CPU Unit with the time units set to 0.1 ms, the Error Flag will go ON if C is not
between 5 and 9,999 decimal (0005 to 270F hex).
• When using a CJ1-H-R, CJ2H, or CJ2M CPU Unit with the time units set to 0.1 ms, the Error Flag will
go ON if C is not 0 or between 2 and 9,999 decimal (0000 or 0002 to 270F hex). (See note.)
• ON if N is set to 4 or 5 (scheduled interrupt designation) for a CJ2H CPU Unit and the synchronous
unit operation function is enabled.
• OFF in all other cases.
