Method for realizing hybrid programming by embedding high-level language into ladder diagram

Abstract

The invention relates to a method for realizing hybrid programming by embedding a high-level language into a ladder diagram. In the method, a high-level language program taken as a module is inserted into the ladder diagram, and the inserted grogram module is stored in a file in a function type. The high-level language program file and a machine instruction code generated by the ladder diagram program are compiled into an executable file to be downloaded on a PLC (Programmable Logic Controller). In running, the high-level language program module is called from a machine instruction generated by the ladder diagram program so as to execute the high-level language program module. By embedding the algorithm module compiled by the high-level computer language in the ladder diagram, the method solves the problem that a complicated algorithm is difficult to realize; and by utilizing the advantages of stability and reliability of the ladder diagram, the development efficiency of a complicated control system is enhanced, and the aim of enhancing the functions of the ladder diagram can be realized by embedding an intelligent algorithm at the same time.

Description

technical field [0001] The invention belongs to the field of computer information technology, and relates to a method for implementing mixed programming by embedding a high-level language in a ladder diagram. Background technique [0002] For a long time, PLC has been widely used in the field of industrial control. The ladder diagram is the main means of PLC program design, which has the advantages of simple use, intuitive and clear. However, PLC is mainly used for logic control, so the ladder diagram is easy to use when designing logic control programs. However, as the functions of the controlled equipment become more and more complex, simple logic control can no longer meet the needs of equipment control. Therefore, in order to meet the actual needs of enhancing PLC functions, it is often necessary to add intelligent algorithms to the original logic control, but the process of implementing the algorithms in the ladder diagram is too complicated. Computer high-level progra...
