7.20.1 High speed interrupt program execution
The high speed interrupt program execution function is designed to run an interrupt
program according to the setting of high speed interrupt pointer I49.
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.
Set within the range 0.2 to 1.0ms.
Note the following when executing a high speed interrupt program.
(1) The high speed interrupt program is only executed as interrupt enable.
(Refer to Section 7.20.3 (3) for the items that delay high speed interrupt's start
from interrupt disable.)
(2) 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.)
