The methodologies include: 1) a means to store information about the structure of a ladder diagram and display the ladder diagram on a CRT screen, 2) a means to convert the ladder diagram information into its equivalent Boolean code, and 3) a means to convert Boolean code into its equivalent ladder diagram information.2 volumes (ix, 278 leaves)BTDapplication/pdfIn CopyrightLD5655.V855 1985.S665Ladder networksMicrocomputers -- ProgrammingProgrammable controllersToward the development of a universal programming/documentation system for programmable controllers on a host microcomputerThesishttp://scholar.lib.vt.edu/theses/available/etd-03122013-040319/
