6.22 High Speed Interrupt
Basic
Note6.69
When an interrupt program is created using the interrupt pointer I49, the QnHCPU can run
Process
a program by making high speed, fixed-cycle interrupts at intervals of 0.2ms to 1.0ms.
And, the QnHCPU improves the I/O response by refreshing the I/O signals and intelligent
Note6.69
function module buffer memories in the parameter-set ranges before and after the
Redundant
execution of the high speed interrupt program.
This enables accurate control such as precision position detection.

The Basic model QCPU, Process CPU, Redundant CPU and Universal model QCPU do not
support the high-speed interrupt function.
The Q02CPU does not support the high speed interrupt function.
When using the high speed interrupt function with the QnHCPU, check the versions of the CPU
module and GX Developer. (
