1) TM instruction: Clocking is not performed. If it is not executed once during a single scan,
the correct time cannot be guaranteed.
2) CT instruction: Even if count input is ON, counting is not performed. The elapsed value is
retained.
3) SR instruction: Even if shift input is ON, no shift is performed. The contents of the
specified register are retained.

is processed as follows when the LOOP instruction is executed.
