A Method of Memory Mapping for Mixing Programming Language and Manufacturer-defined Language

摘要

The present invention is a user function/function block supported by the IEC language to increase the user's maintenance convenience and to reduce the execution period and reduce costs by enabling users with different familiar programming languages to collaborate when jointly performing a project. It is to provide a memory mapping method that integrates the language defined by the manufacturer into the IEC language using the function. In the memory mapping method for mixing the programming language and the language defined by the manufacturer according to the present invention, (A) a language setting window supporting the second language in the user function/function block of the first language is added to the PADT (Program And Debugging Tool) to do; (B) writing a program in a user function/function block in a second language selected in the added language setting window; (C) generating a mapping table for mapping the first language and the second language to each other through a table generating unit; (D) mapping the variables to be used in the program with the second language set in the language setting window of the PADT based on the generated mapping table through the mapping processing unit; and (E) converting programs written in different languages into one language based on the variables mapped by the mapping processing unit through the assembly conversion unit.
