Interrupt Input Units are used to execute interrupt programs on the rising or
falling edge of an input signal. When the specified interrupt input turns ON (or
OFF), execution of the cyclic program in the CPU Unit is interrupted and an
I/O interrupt task (task number 100 to 131) is executed. When execution of the
I/O interrupt task has been completed, the cyclic program is again executed
starting from the instruction after which it was interrupted.
