This section provides the cautions when executing the high speed interrupt function and
Process
the restrictions.
Depending on the cautions, an WDT error may occur, or high speed interrupt may not be

executed at preset cycle intervals.
Redundant
The items are classified into 4 types depending on the restriction level.
Note6.63
High
Performance
Note6.64
The time taken to run an interrupt program once should not exceed the preset time of the
interrupt cycle interval. (Make sure the time required for an interrupt program once is
within the preset time of the interrupt cycle interval. Otherwise, high speed interrupt
operation cannot be guaranteed.)

6.22.4 Restrictions

(1) Items that are completely disabled.
(2) Items that are restricted on the high speed interrupt.
(3) Items that have priority over the high speed interrupt when interrupt is disabled.
(4) Items other than (1) to (3)
Table6.41 Items that are completely disabled
Restriction
Only the CPU modules listed in Section 6.22 (1)
support the high speed interrupt function.
QA1S6 B or QA6 B base unit is not
available.
Multiple CPU system is not available.
PR/PRC, UDCNT1/2, PLSY, PWM, SPD,
PLOADP/PUNLOADP/PSWAPP instructions are
not available.
Instruction that will take longer processing time
than high speed interrupt cycle is not available.
Programming unit is not available.
The following two SFC functions are not
available.
• SFC transition monitor check function using
SM90 to SM99, SD90 to SD99
• Fixed-time executed block execution function
Time-based sampling trace is not
available.(Sampling trace can be used every
scan or when detailed conditions are executed.)
Interrupt program (I0 to I48, I50 to I255) and
fixed scan execution type program is not
available.
Since the Basic model QCPU, Process CPU and Redundant CPU do not support the high speed
interrupt function, it is not necessary to be conscious of the description in this section.
Since the Q02CPU does not support the high speed interrupt function, it is not necessary to be
conscious of the description in this section.
When Used
Parameter error is detected.
Parameter error is detected.
Checked at parameter setting of GX Developer.
Any of the instructions indicated on the left is not available and error is
detected.
Since interrupt is disabled during instruction execution, high speed
interrupt is not available at preset cycle.
Response to instruction search will be slow, or communication error
may occur on programming unit side.
Functions given on the left are not available and are ignored.
Sampling trace is not available and is ignored.
(When trace read is performed, data may not be set.)
Since multiple interrupts are disabled, high speed interrupt is not
available at preset cycle while any interrupt or fixed scan execution type
program is run.
