I/O Interrupts - Delta Electronics AH500 Operation Manual

instruction TKON/TKOFF. Users can set the initial state of a cyclic state.
Please refer to the figure below. After users click a cyclic task in the Task Manager window, they can set
the initial state of the cyclic task in the Task Description section. If the Active checkbox is unselected, the
cyclic task will not be executed until it is activated by the instruction TKON in the POU assigned to another
cyclic task. Please refer to AH500 Programming Manual for more information about the instructions TKON
and TKOFF.

AH500 series CPU modules provide various kinds of interrupts. The interrupts provided by AH500 series
CPU modules will be introduced in the following sections.

8.5.3 I/O Interrupts

There are 32 I/O interrupts (I0~I31).
I/O interrupts are used by special high-speed modules. Users can set interrupt conditions and interrupt
numbers for a special high-speed module by means of HWCONFIG, and download the program created in
ISPSoft to the special high-speed module. If an interrupt condition is met when the high-speed module runs, the
corresponding interrupt will be executed.
Take AH04HC-5A for instance. The steps of setting AH04HC-5A are as follows.
(1) After users click CH1~4 parameter setting in the Parameter Setting window, they can set
CH1/CH2/CH3/CH4 compariosn function, and CH1/CH2/CH3/CH4 comparison interrupt output
selection.
