The Ladder Chart have been used to the presentation of programs on the Programable Sequence Controller (P.C.) as same as on the electric sequence circuits consisted of relaies. But, it is unsuitable method for the presentation of programs on P.C. because which involves new codes of micro computor never seen in sequnce circuits of relaies. The new description method using Boolean Algebra and the new symbols for new codes is prefered. This method gives a logical presentation and the convenience of progam coding.
