The Q02CPU does not support the high speed interrupt program function.
Note6.58
Set the high speed interrupt pointer I49 at "High speed interrupt I49 fixed scan
interval" after choosing "PLC system" - "System interrupt settings" - "High speed
interrupt setting" on the PLC parameter screen.
Diagram 6.81 High speed interrupt setting
(a) High speed interrupt while interrupt is disabled
The high speed interrupt program is only executed as interrupt enable.
Refer to Section 6.22.4 (3) for the items that delay high speed interrupt's start
from interrupt disable.
(b) When high speed interrupt is ignored
If the interrupt disable period continues longer than the set interrupt cycle interval,
high speed interrupt may be ignored.
High speed interrupt is ignored once when it occurs twice during interrupt disable.
