Each interrupt is generated based on the high-speed counter value and record unit value.
Example:
Right-click the interrupt program INT_01 and
INT_02 in the program block, choose Property >
Interrupt Event, and set them to I001 and I605.

The process of compiling the left-hand program in
AutoShop is as follows: Right-click the interrupt
program INT_01 or INT_02 in the program block
and choose Property, and then name 01 or 02 as
needed.
During the PLC's execution process, the interrupt
insertion subprogram A or B is executed when
any of the following conditions is met: the
scanning proceeds to a point between EI and DI
instructions; X0 is set to ON; the timer 5MS times
out. When subprogram execution proceeds to
IRET, the PLC returns to the main program and
continues execution.
