Interrupt Input Function

This function generates an interrupt from an input module.
Operation
An interrupt operation depends on the condition set in module parameters. In addition, an interrupt condition can be set for
each point.
When "interrupt condition setting" is set to "leading edge/trailing edge", an interrupt factor occurred during execution of an
interrupt program is held only once, and the second and subsequent factors are ignored.
If "fall  rise" occurs during execution of an interrupt program to be triggered by a rising edge, the second rising edge does
not trigger the interrupt program. Because of this, provide an interval between on and off of the interrupt input (also same as
"fall  rise  fall").
In addition, a continuous interrupt input of signals with a short ON width and OFF width causes frequent halts of the main
routine program. Adjust the ON width and OFF width for interrupt input not to interfere with the execution of the main routine
program.
Setting method
Set the interrupt method from "Interrupt setting".
