ABSTRACT:
An editor apparatus and method for programming industrial controllers in relay ladder language, the apparatus or method used to provide RLL logic to control machine tool movements in a desired sequence. The apparatus includes a display for creating a bar chart image that represents all functions in a cycle and graphically illustrates all function contingencies. The apparatus gleans function, cycle and contingency information from the image and, based on the information, creates modules that include logic required to make each function contingent upon illustrated conditions. A compiler then compiles the modules to provide an RLL program section to control the cycle.
