This article contains description of a new programming method of PLC controllers, presently a fundamental tool in discrete process auto-mation. A PLC user, applying standard languages for programming of sequence processes, is forced to rely on intuitive methods as well as his own experience. For this reason, the authors attempted to work out a method, which would allow for simple execution of the program-ming process with no limits regarding number of steps and input and output signals. The result of these studies is a method named Graftech by its authors. The method consists in determination of a functional program in LD language, basing on process algorithm written with SFC network. The rules concerning determination of the functional program are also described. Application of Graftech method is illustrated with an example of automatic ejector of casting molds.
