About the experience of design ladder program design is the application of programmable logic controller of the most critical issues, PLC ladder programming methods commonly used are: experience design, design of sequential control and logic design, such as algebra.
PLC ladder program of "experience design" to prepare, the relay is used for circuit design approach to the design of ladder, that is, in some typical circuit based on the plant control system for specific requirements, and continuously modify and improve the ladder. Sometimes repeated many times to debug and modify the ladder, continue to increase in the middle of programming components and auxiliary contacts, and finally to get a more satisfactory results. Therefore, the so-called experience design is the use of the experience (some typical control procedures, control procedures, etc.), their re-combination or transformation, and then repeated after several modifications in order to work out the control procedures to m
