Abstract
A method and system for generating a control program executable by an industrial controller, wherein the control program is formed using instructions from a high-level text-based language and instructions from a ladder-based language. A source program is received by a host computer. At least one instruction of the source program in the high-level text-based language is displayed on a display device along with a corresponding ladder diagram of the source program in the ladder-based language. The source program is edited in either the high-level text-based language using a first editor or the ladder-based language using a second editor. Modifications of the source program made using the first editor and the second editor are converted to a lower-level language representation. The lower-level language representation is convertible to both the high-level text-based language and the ladder-based language, so that modifications made in the high-level text-based language dynamically update the ladder diagram display and modifications made in the ladder-based language dynamically update at least one line of displayed text.
