The primary objective of the redundant design is to make the control system more reliable and safer. ln spite of the more investment. the redundant design can decrease maintenance cost and operating labor. The paper introduces the construction and redundant characteristics of the SEIMENS TELEPERM M DCS. According to the re(Iuirement of technology. the necessity of the redundant design of AS235H system is clarified. At last. this paper suggests that it is useful to introduce the advanced technology and choose the proper type.
