Abstract: A method of annotating a specification of a programmable logic controller is provided that includes displaying a graphical element in a first graphical language for programming the programmable logic controller, and displaying a comment associated with the graphical element. A method for converting a specification for a programmable logic controller in a first language to a second language is provided that includes converting a first instruction in the first language to a second instruction in the second language, and converting a first comment associated with the first instruction to a second comment associated with the second instruction. A computer-readable recording medium is provided.

Abstract: A method is provided for graphical presentation of objects and/or technical processes on a screen, as well as an editor implementing the method being provided. A tooltip appears when a pointing device such as a computer mouse for example uses its mouse pointer to remain for a predetermined time over a predetermined section of the display area, and that the tooltip graphically presents at least a part of the object and/or of the process in a modified way compared to that shown in the display area. In this way, with the aid of the tooltip, the same object and/or the same technical process can be presented in a number of views.

Abstract: The invention relates to a method for graphical presentation of objects and/or technical processes on a screen, as well as an editor implementing the method. For the graphical reproduction of objects or the illustration of technical processes it is frequently necessary to work with a number of views. In most cases an overview representation is required as well as one or more individual representations of part of the object or of the process. With graphical user interfaces there is thus the requirement for switching between these different views, with the user rapidly losing the overview in the case of a number of views.
