Reliability design of PLC-based control system

Abstract

With the development of information technology, PLC is more and more widely applied to the automatic control of industrial equipment. The reliability of PLC-based control system directly affects production safety and equipment application. The ability to resist interference is the key factor concerning the reliability of PLC-based control system. From the design perspective, the paper analyzes the reliability of PLC-based control system, including the method for reliability improvement.
