8.4 Interrupt input function<br />

Function<br />

When the signal state of the interrupt input is changed from OFF to ON (or ON to<br />

OFF), the corresponding I/O interrupt program is activated immediately.<br />

Up to 2 interrupt inputs can be used. The interrupt generation condition can be<br />

selected either rising edge (OFF to ON) or falling edge (ON to OFF) for each input.<br />

The I/O interrupt program #3 is corresponding to the interrupt input 1, and the I/O<br />

interrupt program #4 is corresponding to the interrupt input 2.<br />

Hardware condition<br />
