ABSTRACT

Sequence function chart is the preferred language for sequential control system design, but its audience is not as wide as ladder diagram. In order to realize the standardization and high efficiency of ladder diagram sequence control design, based on the program structure of sequence function chart of GBT 15969.3-2017 programming language, the design method using ladder diagram is summarized, supplemented and standardized. Firstly, according to the function of the instructions used, the six sequential control design methods of the ladder diagram are divided into three categories: set / reset instruction class, step instruction class and data register operation class. Secondly, according to the development rules of sequential function diagram, a new programming method for sequential control design according to jump class instructions is developed. According to the program execution flow analysis, this method is closest to the execution process of sequential function chart program. Finally, it compares the performance gap of the same sequence function chart from three aspects: the influence on the program scanning cycle, the repeatability of components in the program, whether it is easy to force, package and macro step structured programming. The results show that the jump instruction class programming method can effectively avoid the defects such as waste of component resources, long scanning period and contradictory conversion conditions, and retain the advantages of sequential control design method, which is more obvious than other programming methods. The research results can provide selection conditions and standard methods for the design of ladder diagram sequential control system.
