Interrupt Example for Interrupt Module
In the following example, when X40 is on, the interrupts will be enabled. When X40 is off
the interrupts will be disabled. When a interrupt signal X1 is received, the CPU will jump to
the interrupt label INT O 1. The application ladder logic in the interrupt routine will be
performed. The CPU will return to the main body of the program after the IRT instruction is
executed.
