Abstract： Aiming that the ladder diagram（LD） language is incompetent in realizing complex algorithms，a mix programming method of ladder diagram and C language was proposed. The component technology for ladder diagram implementation was analyzed and the way to embed C language inside ladder diagram was introduced. Experiments were carried out based on the computer assist special system（CASS） platform. Results show that the proposed method is fit for complex algorithm implementation，and the code size could also be reduced.
Key words： ladder diagram（LD） ；C language；mixed programming；computer assist special system（CASS）
