10-4 Interruption [EI], [DI], [IRET]
XD/XL series PLC have interruption function, including external interruption and timing
interruption. By interruption function we can deal with some special programs. This function
is not affected by the scan cycle.
10-4-1 External Interruption
The input terminals X can be used to input external interruption. Each input terminal
corresponds with one external interruption. The input’s rising/falling edge can activate the
interruption. The interruption subroutine is written behind the main program (behind FEND).
After interruption generates, the main program stops running immediately, turn to run the
correspond subroutine. After subroutine running ends, continue to execute the main program.
